Look at this ultimate sleeper truck!
The mere size of a digger sale derrick (sleeper truck)is a strong indication of just how dangerous it could be to handle one without the right knowledge of its proper use. The key to proper operation of these vehicles is through operator training, which is outside the scope of OSHA’S certification requirements Recently, the National Commission for the Certification of Crane Operators (NCCCO) was took over the role of providing written and practical exams for these specialized vehicles. The training is conducted to ensure that operators are equipped with the right skills and knowledge that is necessary to safely accomplish the various tasks to which the truck is assigned, including the digging, setting, and guiding of utility poles into place.
The NCCCO provides two separate types of exams – the written examination and the practical test. Fundamentally, each test is given to measure theoretical know-how, safety regulation concepts, and their applications in an actual work setting.
For the written exam, an applicant must sit in for paper/pencil testing (PPT). This is done after submitting all required paperwork and paying appropriate fees. The date scheduled for the test is given two weeks after the candidate files an application; while the location is provided three months prior to the actual test. Those eligible for PPT will get an admission letter one week prior to the scheduled date, confirming the approval of the submitted application.
The exam is comprised of various concepts and theoretical framework. Basically, it measures five different aspects, including site evaluation, inspection before operation, actual operation, technical knowledge, and importance of printed load charts. It also covers the knowledge obtained on power line hazards, safety regulations and practices, inspection before travel, use of PPE, system controls, decals and placards, knowledge on federal regulations, dielectric regulations, standard signal methods, rigging procedures, and the use of manufacturers load charts. Knowing these concepts is vital to pass the first phase of the exam.
For the practical exam, there are seven tasks that must be performed; however, prior to the examination, a candidate must undergo the briefing and familiarization before testing, in sequence. These tasks include the use of the checklist for inspections before operation where the candidate is asked the five most important checklist items of the digger derrick and what deficiencies to assess. After this, familiarization will follow in order to give the candidate ample time to become comfortable with the different controls of the machine and then will eventually be asked to lift the chain off the ground. The next task is to identify the four hand signals in bringing the chain back to the original position.
Most importantly, a participant will be asked to safely unfold the auger onto the ground and put it in the correct position for digging, followed by boring a hole, then folding the auger back into its proper position. Part of the task is to correctly pick up a utility pole, place it in the designated location, and maneuver the boom in a cradle position before leaving the testing station.
In the construction industry, accidents, derailment, and other such incidents happen every day; digger derrick operators have a fundamental role to play in the safe operation of this versatile vehicle. The biggest challenge is to operate these machines in the safest manner possible in order to minimize the risks and hazards brought about by such a unique design. The NCCCO offers training to registered participants to learn fundamental skills and knowledge that are crucial for safe driving of the digger sale derrick. After passing the written and practical exams and complying with NCCCO’s substance abuse policy and code ethics, operators can earn certification and be on the way to a great career!
Safety is a main concern when working with any kind of industrial equipment such as a vacuum truck. It is certainly important that all safety procedures be followed and all protective equipment used in order to prevent an accidental injury. In spite of the knowledge of such basic precautions, there are still times when the risks aren’t quite as obvious and it is easier to get the job done more quickly without taking such preventive measures.
One area that is certainly susceptible to such ‘risk-taking’ is with hearing loss; this is especially important when using a combination vacuum truck unit that does both powerful jetting and vacuuming on the various work that is done to get sewer pipelines clean. This hard-working unit in particular makes a lot of noise, more so than the normal single use suctioning version. Exposure to the sound levels common with this unit can certainly add up over the years; the problem is that it does often take years to be noticed – and that’s when it is so easy to avoid the use of proper hearing loss safety gear.
Hearing loss, although not always a prevalent thought, is actually a great risk when using any kind of loud equipment which makes it very important to recognize the potential for such an occurrence and protect workers while operating combination vacuum trucks at work sites.
How Hearing Loss Happens
The human ear is an intricate and very delicate part of the body that can definitely suffer damage affecting the ability to hear when not properly monitored and protected. Exposure over extended periods of time to loud noise at 85 decibels or higher affects the inner ear structure in ways that cannot be repaired. Strong vibrations pass through the eardrum and into the inner ear bones and cochlea, where the vibrations are amplified even more, causing damage. With enough continual exposure to loud noise such as that generated by a combination vacuum truck, the cochlea’s ability to function properly is affected; a ringing sound is produced within the damaged inner ear and normal hearing is affected.
This is important information to know because it is not common knowledge how easy it is to damage the inner ear with 85 decibels during vacuum truck operations; as an example, this level of sound is loud enough that people need to raise their voices to hear each other. Of course, if the noise level is higher than that, damage occurs more quickly. Some sounds can be so loud that if heard in close range, immediate and permanent hearing loss can happen. Most vacuum trucks create noise in the 100-decibel range, so anyone using such equipment daily is at prime risk for hearing loss.
Need For Job Site Hearing Protection
There are two ways in which hearing can be protected when operating vacuum trucks: with earplugs or earmuffs. Neither of these things remove all sound altogether; however, it does reduce the sound to a level that will not cause inner ear damage. Disposable earplugs are available in a range of noise reduction ratings or NRR as it is known; so it is important to use ones that provide enough protection to lower sound levels well below 85 decibels. Earmuffs can be used alone or with earplugs if enough protection is not being provided.
In either case, the most important thing is that this safety gear actually be used during every operation. Vacuum truck pump and motor technology has seen advancements that offer efficient functioning with lower noise levels due to lower rpm’s, which benefits both the truck and its operators.
Dealing with 100 decibels and more of constant noise from vacuum trucks does not take long to cause permanent hearing loss when immediate problems such as reduced hearing or ringing in the ears is not actually happening at the time. For this reason, it is important that operators of these noisy yet productive vehicles understand the risks to hearing and use protective gear every day, without fail!
Every heavy-duty vehicle should be carefully operated in order to ensure that safety can and will be given a top priority. When working with vac truck for sale, it is likewise true that the operation of this massive extraction machine must be carefully and skillfully handled to make every job operation as safe as it can be.
While proper training on the use of these vehicles is of high importance, it is also necessary that the entire job site be carefully monitored and controlled as well. Such action could involve anything from being sure that bystanders do not get too close to the work area to how well the vacuum truck equipment is used when in operation. Preventing accidents, injury, and any other problems including damage to the equipment is dependent upon having a level head and good control of the work site.
Practice Correct Equipment Use
It is important that everyone involved in the vacuum truck operation understand a few important yet basic aspects about the safe and correct use of this massive vehicle. The truck itself should be positioned so that there is as straight a line as possible from the vehicle to the work site with as few bends as possible. A straight line from the pump site to the vac truck for sale is optimal as it allows for the least amount of friction and obstructions, thereby reducing the chance of clogs occurring in the hose line.
Use hoses that have the largest possible diameter as that will help to increase job efficiency; be sure that the end of the hose is properly clamped to the vacuum intake. All hoses being used should be of the same diameter; also be sure that a safety relief valve has been installed along the line. In taking these important steps, fewer problems getting the job done should be encountered.
Protect Operators and Bystanders
When working with vacuum trucks and even when a job seems completely safe and easy, it is vital to follow all established operational rules and guidelines especially regarding the safety of anyone else around the job site. This may require having another worker handle traffic control if working on a traveled street or simply keeping homeowners away from the job site when working in residential areas.
Set up signs or cones if necessary so that oncoming traffic is alerted that work is occurring; a second worker should be posted to watch for anyone coming near the truck or pumping area. Section off as large of an area as possible around the work site to create a buffer zone to prevent any vehicles or bystanders from getting too close, which can be a lifesaving option for both workers and the public.
Make Safety a Top Priority
Even though it may seem as if using a vacuum truck is a fairly safe job with accidents an unlikely occurrence, not focusing on the entire job operation can cause accidents and injury to both workers and others who may be in close vicinity of the work site. Following all safety procedures in regard to truck positioning, equipment set up, and other safety factors is essential and should never be taken for granted. Correct procedures while actually performing the job as to proper equipment use as well as wearing all protective gear is important to prevent injury to those performing the actual job operation. It is also essential to have a plan of action in case any problems should arise, whether with the equipment, workers, or bystanders.
The best fleet crews are those who know the job well and always stay safe during the procedure. Companies should provide refresher courses for all workers on updated safety measures, the correct use of vac truck for sale equipment, and all other means of keeping every job site under excellent control!
In the world of industrial equipment, no other basic tool is available in so many different configurations as the national crane. The varieties are many and each one is able to perform different jobs in many different ways. When looking for the best vehicle to buy, it is important to understand that all these vehicles are capable of lifting large and heavy material; however, not every one of these useful vehicles is created equally. Finding the right version for the required job involves a careful assessment of each type, its many features and equally any limitations. Consider the following listed elements when considering the purchase of a crane truck.
Job Site Applications
There is indeed a big difference between working on city streets with light industrial type crane trucks and working at a major construction site or on loading docks at a harbor with a much larger vehicle. In most cases, all versions can accomplish the same basic job; however, the vehicle itself must be suited for the terrain and the workload at each individual job site. This means that the weight of the vehicle, the weight of any load that will be lifted or carried, and the ease with which the vehicle can be maneuvered must be considered in order to come up with the right model and type selection. Truck cranes for various types of work sites range from a standard, smaller sized chassis on standard wheels and tires to massive mechanical arms on large trucks with giant, off road and rough terrain tires.
Different Booms for Different Jobs
There are three basic types of booms that are usually seen on truck national cranes, each performing differently and for different applications:
Stick or Straight Boom – A straight, long boom arm is run with hydraulics or cables. A standard arm crane can lift considerable amounts yet are limited in how much payload the vehicle can carry, since the lifting arm is stowed across the rear bed of the truck. Standard crane trucks are useful in most situations; however, they are limited in both height of lift and maneuverability since the arm is one piece and at the most can only rotate on its base.
Telescoping Boom – Similar to the standard arm boom, a telescoping crane also requires a large amount of storage space on the vehicle and is limited in maneuverability which is made up for with its power. Since it expands to much greater lengths than most straight arm lifting trucks can handle, the telescoping arm can be ideal for long reaching situations when a greater range of both height and distance are necessary. These hydraulic lifting vehicles are made of multiple pieces that all collapse into each other yet when fully extended offer a much greater reach.
Knuckleboom – This multi-purpose crane is highly useful and able to complete a wide range of jobs. Although a knuckleboom may not have the extreme length of telescoping and straight arm versions, that deficiency is make up for with great maneuverability. The articulated, jointed lifting arms can lift loads as high as both other types of cranes while working very close to the job site. Because of the knuckleboom’s different approach to lifting, which is more upward than outward, these units can be smaller and lighter yet stable and able to provide ample lift height and power. An additional benefit is that the jointed arms fold up quite compactly, leaving great usable payload space on the truck bed for carrying material, therefore reducing the need for a separate vehicle.
By matching up the job requirements with the varied strengths of these versatile national crane trucks, the right vehicle can be found to accomplish almost every job requirement. Other than the most extreme lifting situations, knuckleboom trucks are a favorite on many construction and work sites. All three of these types of cranes have a useful role and should be considered for purchase based on the jobs that will be done!
In any kind of industrial or semi-industrial line of work, the equipment should be built to perform a particular job in order for companies to run efficiently. In the septic business, one of those critical aspects is being sure that septic trucks for sale are built on the right truck chassis. As expensive as these vehicles can be, knowing the vehicle’s actual framework and functioning parts can withstand the rigors of the job is just as important as all the other qualifications that there should be.
Chassis Weight Concerns
Most septic trucks for sale are built on a medium or heavy-duty, industrial grade frame due to the amount of abuse that these trucks put up with on a daily basis. Even though a few companies actually run smaller units, for example regular heavy-duty pickup trucks with slide-in tanks for small jobs like portable restroom pumping, the truck chassis and especially the suspension should be rated to handle the constant load it will be forced to carry. Failure to do so can lead to vehicle overload, which can result in damage to the truck’s frame, suspension or drive train.
Considering that every gallon of waste in a pumper tank weighs over eight pounds, such weight can really add up. It does not take much to overload smaller vehicles, which is why most companies who pump use the light industrial models at the very least. In addition to the concerns of engine and transmission strain, using a truck that is not equipped to carry very much weight on all kinds of roads can be risky. Weight shifting, frame twisting, and other fatigue-related concerns could cause big problems.
Having a solidly built truck frame and body means nothing if the drive train cannot continually provide the necessary power. The motor must be able to withstand keeping a loaded vehicle moving and driving from a standstill, which puts a lot of strain on the motor to get all that weight rolling again. The coolant system should be strong enough to handle such a load, as excess engine wear and breakdowns will occur if it is not. The transmission needs to be powerful enough to propel a loaded vehicle on less than perfect roads. Weakness in any of these areas is an invitation for either continual breakdowns due to excess stress on the truck or simply not getting the intended life out of the vehicle. So being underpowered can cost a company long-term profits.
Besides the obvious weight and drive train power concerns, it is also a good idea to review each type of vehicle for what kind of recalls have been experienced, including the usual breakdowns and repairs, maintenance requirements, driver comfort and convenience, and whether or not a particular chassis is suited to company needs. They way in which a vehicle will be used and how it will handle such use will depend on many things such as the type of pumping that will be done, the terrain on which the vehicle will be driven, the typical weather in the area, and more; however, it is still possible to compare units to see which ones are better suited to individual company purposes.
Sometimes this can mean spending more than initially planned, yet buying an underpowered vehicle could waste more money in the long run. Buying used can be an option as well, although the same cautions still apply. In order to get a decent lifespan from a vehicle that has already been used, it is important to know if it was used within its limits and is still capable of future use.
It is essential for septic companies to honestly evaluate the work that will be done, the strain that will be put on the vehicles, and then buy accordingly. Whether pumping portable toilets or huge septic tanks, there are numerous vehicle chassis available so that the right septic truck for sale for the job is purchased!
No matter what industry or how a great safety record, the chances of an accident with vacuum trucks always exists. Accidents for these vehicles can involve spills of whatever material is being hauled within the vacuum tank, creating a messy and potentially dangerous situation. Because of the nature of its contents, a vacuum truck accident can create a hazard that is much more serious than initially estimated, requiring special effort to safely clean up the discharge – and the best way to deal with spills is to be prepared for them ahead of time.
When a discharge happens, the following steps should be taken:
Try to Stop the Spillage - The correct course of action will depend on the contents of the truck tank. If at all possible, determine what part of the vehicle is leaking and why, trying to stop the discharge as quickly as possible in the safest way possible. Clear the area where the spill occurred of people as a precautionary measure; keep the entire affected area sectioned off until all leakage has been stopped.
Make Necessary Calls and Contacts – Once the spill situation is under control, the most important thing to do is to call the trucking company’s office and report the incident, then make any necessary calls to local and state regulatory health and environmental authorities. These contacts will provide information as to the next steps to remedy the problem, usually involving immediate clean up of as much of the spill as possible, followed by sanitizing of the area. Once a plan for removal and site sanitizing has been decided, it is a good idea to notify the owner of the property, explain what happened, and what will take place to clean the site and sanitizing the area afterward.
Clean Up the Area – After receiving appropriate instructions, cleaning up the accident location is usually the next priority. If spilled material can be re-vacuumed into a truck – either the same vehicle if it has been repaired or another empty one – vacuum up as much of any solid or fluid contents as possible. The area should then be treated with lime, bleach water, or whatever preparation are required under the circumstances in order to decontaminate and sanitize the area.
Further General Actions – It is likely the local health department will check the site to ensure that clean up has occurred according to regulations, so it is important to be thorough with all clean up actions. Afterward, those operators involved with spills are usually interviewed by the appropriate state’s environmental protection agency about the incident, often requiring that a written account of the event be provided.
Future Plan of Action -Vacuum truck companies should have an existing plan that covers all of the above points so that if a spill should happen, handling the issue is done quickly and expertly. Carrying essential spare parts on every vehicle can be helpful for onsite repairs. It is also recommended that each truck be operated by two employees for just such an event, as it is unlikely that one operator alone would be able to prevent an entire tank from emptying without some kind of assistance. Drills should be conducted with all crew members to teach the proper way to handle spill emergencies according to company policy. All vacuum trucks should be kept in excellent condition through regular, routine maintenance and immediate repairs when required.
Septic spillage or other vacuum truck mishaps are never easy to face; prevention through safe vehicle handling and maintenance is the best way to operate any vacuum truck service. In the inevitable event of an accident, how the incident and the vehicle are handled in order to minimize spillage and maximize clean up efforts will reflect greatly on a company and its ability to run a safe vacuum trucks or septic business!
Companies looking to gain increased productivity and use from heavy-duty equipment should consider purchasing or upgrading to knuckleboom trucks. As the technology in construction and industrial equipment has continued to advance, a large percentage of stick boom cranes and other similar units have been replaced by a more versatile truck and for a lot of very valid reasons. Even though the initial cost may be a little more, investing in one of these vehicles usually ends up saving a lot more money in the long run.
Better Performance Record
There is a certain amount of opinion that knuckleboom trucks offer less usefulness than other lifting vehicles, this could not be further from the truth. Not only can these trucks do everything a regular crane can do, the flexibility and maneuverability actually offers even greater usage potential. Lifting is only the start of what can be accomplished with an articulating crane; because of the way that they are built with a collapsible boom tucked behind the cab in most cases, knuckleboom trucks wind up with a lot more space available to carry loads as well. The fact that the boom is jointed does not affect lifting capacity either, which is a common misconception. The truth is that knuckleboom cranes can lift as much, if not more, primarily because it is much easier to get close to the actually lifting point than the regular crane.
In addition to the above, these units are available in many sizes and load carrying capacity in order to promote safe lifting through correct weight distribution. Most units also have advanced safety features like radio remotes and built-in overload protection systems, which are also used on standard cranes but are more advanced in the knuckleboom version.
Many Jobs, One Truck
One of the best benefits in having a knuckleboom truck as part of a fleet is that there really is no limitation to the potential uses for these vehicles. No matter what the lifting job, an articulated crane or knuckleboom truck can handle it. Besides lifting, the vehicles can also be run with various equipment attachments such as: shovels and scoops; augers to drill holes; buckets; man baskets; forklifts’ loaders; sifters; pole setting equipment; and much more. Material can be loaded, carried to the job site, and unloaded without the need of any other units as well as carrying, drilling, and setting utility poles – all with only one or two operators as well. The possibilities are endless when using a crane that can fold, bend and turn, making it possible to maneuver in even the smallest of spaces where other equipment would never reach.
Fewer Expense Costs
With so much flexibility – both in the crane itself, and the different jobs it can perform – it should be easy to see some of the many benefits that are possible with a knuckleboom truck on every fleet. There is another benefit offered for those companies not needing the size and length of a standard stick boom crane; smaller articulated units weighing less than 15,000 pounds and with a maximum boom length of 25 feet can be used by operators who do not have to possess a crane operator certificate.
The greatest savings on expenses is that in most cases, a knuckleboom crane on the fleet reduces the need for other specialized units due to the number of possible attachments that make getting just about any type of job successfully completed. Fewer units that used more efficiently offers lower operating expenses, lower insurance premiums, and fewer crew members required to perform the same amount of work.
All in all, knuckleboom trucks provide many answers for companies in need of a highly useful vehicle with the power to lift as well as many other things. Even though the cost may be a little more than the average crane, the savings will indeed be seen and continue on through the life of the truck!
Owners of service trucks are indecisive if installing a National Crane is a necessity to accomplish work more productively. In the construction industry and other such businesses, even if there is not an ongoing need for loading and unloading heavy material, such a lifting device as a crane is almost always a needed item. The way material is currently moved, almost all utility service operations involve lifting and moving heavy or cumbersome material that would be nearly impossible to accomplish by workers dependent upon their own skills and strength. Straining of the back, legs or arms could be a very real possibility.
A heavy-duty lifting device is essential to many business operations for so many reasons and is much more than only preventing serious bodily injuries; it can allow for tasks to be accomplished more efficiently and productively. If crews need to move heavy material like transformers, pipes, culvert parts, or large rolls of electric cables, the use of a crane to transfer such loads from a truck to the desired location is without equal.
The usefulness of this vehicle makes the process of selecting the one that is appropriate and compatible for such use a very important decision. There are many available options available and it is vital to select the one best suited for the application and client need. Some of the different types are listed below.
Primarily, there are 2 types of telescopic cranes and each one of them is different in terms of carrying and reaching capacities.
Electric – This is the best choice if the work is irregular and only moderately heavy. The lifting capacity ranges from 2,000 to 6,000 pounds; working beyond its capacity could have a damaging effect on the electric system. For typical weekly or bi-monthly projects, this vehicle model could be the best option. On the other hand, if the crane will lift heavy material daily and could well exceed its rated lifting capacity, the choice should be the second model.
Hydraulic – If lifting requirements exceed 6,000 to 14,000 pounds or if it is used daily, the hydraulic type would be the best choice. It has a long reach and high carrying capacity compared to electric cranes; the only thing to consider when buying is being sure the lifting capacity that is need will match the truck’s design.
When it comes to productivity and profitability, an articulating crane could be the best option; it can be customized based on each buyer’s preference and application. This is perfect for projects that require lifting material of 14,000 pounds and above as well as for rapid loading and unloading. Not every crane truck buyer is familiar with this particular configuration; however, the versatility and functionality of this model makes it popular in the service vehicle market.
Modern articulating cranes have so many advantages over telescopic versions, being capable of multiple applications by installing the right attachment such as grapples, buckets, forks, or giant augers. Aside from its versatility, it is offers simple usage, precise control, easy maintenance, capable of folding into a compact size, and readily affordable for most buyers.
National Crane trucks can be used in various projects, offering the capability to be deployed as a landscaping machine, a mechanics storage mobile device, and many other options depending on its configuration. These trucks can be customized to fit various projects and offer innovative features to make the equipment the vehicle of choice when there is a need to lift heavy objects. By reading and learning about the above options, buyers can determine which crane is can be outfitted on a service truck for a particular need to meet customer needs and expectations – this is why service vehicles do indeed need cranes!
With the coming of colder weather, companies using vacuum trucks need to think about winter safety and preparing both vehicles and workers for the change in season. Routine maintenance is important for any industrial equipment; however, seasonal changes present specific challenges in the correct use of a vacuum truck for sale. Winter maintenance should be planned for early so the trucks can keep working as much as possible with zero down time due to cold weather problems.
Winter Fluids and Lubrication
One of the main winter maintenance jobs for any vehicle, whether it is a passenger car or the heaviest of all heavy-duty commercial vehicles is changing the fluids to those that will not be affected by low temperatures. Changing to a lighter weight engine oil and making sure that the antifreeze reservoir and windshield fluid contained are filled with non-freezing fluid is common knowledge. In vehicles such as vacuum trucks, the rear differential oil should be changed to a lighter weight viscosity as well as lubricating all the bearings.
Cold Weather Vacuum System Care
In order to keep a vacuum truck pumping in winter, these vehicles require having the vacuum pump fluid changed to a lighter weight. A suctioning truck that doesn’t work because the pump can’t move can cause lost production time and reduced income; it is also a potentially dangerous situation if the vacuum system is not working to its fullest capacity. Refer to the manufacturer’s manual for each vehicle in regard to recommended oil weights and cold weather use.
Besides changing the vacuum pump oil, another extremely important maintenance point for these vehicles is to be sure that the truck is completely drained, which would include the secondary tank, the hoses and the pump itself. While this may take some extra effort, being sure that the entire truck is empty and the pump and all hoses are clean and blown out so that no water is left sitting can mean the life of that pump or hose. Water left in either, or in the tanks, can back up and freeze; at the very least, it can render a truck useless until any water trapped inside is unfrozen. At the worst, it can split hoses and even crack the pump itself since water expands when it freezes; any water sitting inside the pump will have nowhere to go but outward, making for an expensive repair job before the unit will be used again.
General Cold Weather Preparation
Besides the more specialized maintenance items that are listed above, the onset of the winter weather season means bad road conditions in many locations. Being prepared for any cold or snowy weather is equally important, especially when driving a large vehicle that can be weighed down with whatever load is being carried. Always be sure that the tires are in good shape and that winter tires or snow chains are available. Do a complete maintenance check to ensure that the tires are holding the right pressure, fluid levels are staying exactly where they need to be, and that the engine cooling and interior heating systems are all properly functioning. Always flush the radiator and add new fluid as well.
Fall is always a good time for a general tune up to keep vehicles in top running condition while adding any winter weather necessity items as temperatures drop. With vacuum trucks in particular, being able to work all season completely depends upon the correct care and maintenance and taking special care of the unit’s more delicate parts. Being thorough in giving each vacuum truck for sale the winter care it needs reduces the risk of failure once the cold weather hits – and keeping that vacuum truck pumping!
