When certain equipment is operated with limited knowledge and not so-skilled personnel, it can result in poor performance as well as lost time and money. This certainly applies to pumper trucks as without proper training, these powerful trucks will not function correctly and could even be harmful to personnel. When these trucks are operated under proper, safe conditions, it will function with greater efficiency. Below are some tips on how to best use vacuum truck equipment.
- Correct Hose Size – Even a slight difference of hose size can impact vacuum performance. With a 50 percent diameter difference, performance is not going to increase by the same proportion. The decision to use the right diameter can increase performance nine fold.
- Keep Same Size – Use one size of hose on pumper trucks and never change the diameter in the middle of a job as this would be inefficient and dangerous. When starting a job with an 8-inch diameter hose, do not change to a 4-inch diameter one any time during the pumping operation. The vacuum mechanism is designed to suction air for an 8-inch hose at full throttle; with a 4-inch hose, the suctioned material can clog when it hits the 8-inch diameter section. Clogged material can severely impact the air stream and destroy the equipment.
- Correct Hose Length – The length of the hose is another factor besides the diameter. To demonstrate this, get two different lengths with the same diameter, one of which is 100 times longer than the other. It is fairly easy to push air through the shorter one: however, with the longer one, air movement is more difficult.
- Correct Hose Type – A hose with a rough or corrugated interior will function well when cleaning a drainage system for shorter jobs. The smooth bore type is necessary for longer and more difficult suctioning jobs.
- Do Not Enter the Tank – The tank has only one way to enter in and out – and it is a confined space. Never under any circumstances enter into the interior space of the tank. The vehicle may have handled toxic chemicals that could cause a worker to be overcome by the fumes if entering the tank.
- Working Vacuum Releases – Be sure that all three vacuum release controls are working: the manual, the remote release, and the inline “T”. The inline “T” is very important because when it is placed in the hose and triggered, it stops the hose vacuum, which is vital if a worker has a hand or arm suctioned into the hose.
- Ground the Truck – The truck must be grounded to prevent anything that could set off a dust explosion. The industry standard for an air mover states that it should not be used with a140 degree or less temperature flash point.
Using the above tips to efficiently operate powerful pumper trucks will ensure that any job can be accomplished safely and efficiently. It is of course equally important to read the manufacturer’s manual and use the recommended pumper truck settings. All of the above is indeed the best way to use vacuum truck equipment!
