Vacuum trucks used in oilfields are subject to unique demands. This is because they commonly carry more than one type of material. Therefore, managing payload weight in these vehicles is extremely important for keeping trucks in good condition, and within the legal weight limits. Although it might be impossible to know exactly how oilfield vacuum trucks for sale were used previously, companies working with used oilfield vacuum trucks dealers to find the best used units possible, should manage the weight of their loads to extend the life of their newly purchased units. This also reduces the chance of being fined for an overweight load.
Variation in Oilfield Pumping Work
Vacuum trucks used for oilfield work need to be tough, as they encounter many different types of field conditions. It is not uncommon for the same truck to be used to haul wastewater from fracking, sand, sludge, mud and other materials to and from oilfield sites. Therefore, one of the more important considerations when working with used oilfield vacuum trucks dealers to acquire these units, is calculating load weight - or payload.
Consequences of Overweight Tanker Trucks
In general, overweight vehicles present problems. They can damage highways, which are only designed to withstand a certain amount of weight. As commercial truck weights have increased, and more trucks have been found to be operating overweight, this has brought about an increase in trucks receiving citations. Without knowing how much a tanker truck is actually carrying, companies are at risk for weight violations.
On top of this, there is the obvious issue that these trucks are only designed to carry a certain amount of weight. Continual overloading increases truck maintenance, and decreases useful lifespan. Overweight trucks require more fuel to operate, as well. All in all, these are expensive mistakes that can be alleviated by paying better attention to payload, based on tank contents.
Not All Loads Are Created Equal
It would be easy if oilfield vacuum trucks for sale were manufactured to only haul the same material. But since this is not the case, the question of calculating payload becomes an important one. With all the different materials carried by these units, none will weigh the same. This generates the question: “When is a truck loaded to its payload capacity?” It is very easy to overload a truck with materials that have a higher weight per volume than others. This is especially a concern with various waste fluids, as the amount of water and solid material can differ.
Determining Weight Per Volume of Different Materials
The biggest challenge in keeping oilfield tanker trucks within their allotted and legal payload, is to accurately determine the volume of weight of the specific material being pumped. Measuring volume is important, but weight is different per measure, depending on the actual material.
The best solution, as determined by specialists in the oilfield pumping industry, is on-board vehicle scales. Even though this equipment requires an additional investment by a company, giving operators the ability to track payload weight while their vacuum trucks are being loaded is key. The savings in fuel costs, vehicle maintenance, and repair - not to mention removing the risk of citations for being overweight - pay for any additional cost very quickly.
Onboard vehicle scales can be ordered on new vehicles or installed on used oilfield vacuum trucks for sale. Companies working with used oilfield vacuum trucks dealers should inquire which units being offered may already have this equipment installed. If the best used units do not have onboard scales, or a truck is being converted from another line of work, there are a number of options for getting this essential equipment added before putting these vehicles to work in the oilfields!
