Choosing the right septic truck for sale is important when purchasing new vehicles that come in various shapes and configurations. Purchasing the largest one may seem like a guarantee to do all sorts of septic jobs; this isn’t true because different jobs have different requirements; what works on one may not work on another.
Truck size doesn’t always mean the holding tank’s capacity; there are actually more elements that determine the size of a septic truck for sale.
- Number of Axles – The number of rear axles determines capacity. On a small truck, the rear axle may be just one because it is not built for carrying heavy loads. Some trucks have two while others may have three. Having such a number of axles means that it is built for carrying a heavy load and heavier tanks as more axles are needed to safely and evenly distribute the weight of the load when on the road.
- Size of Holding Tank – The holding tank is basically a large steel container located behind the cab where all collected debris is stored before disposal. The size of the holding tank is directly proportional to the amount of content that can be carried. Small septic trucks can hold as much as 4000 gallons of water, while larger ones can hold as much as 6000 gallons.
- Engine Displacement – Engine displacement is the engine power in cubic liters. Septic trucks have an engine for driving the transmission as well as the vacuum pump via PTO. Engine displacement determines how much load can be carried and how much power can be generated to create a vacuum.
- Vacuum Pump Power – The output of the vacuum pump is also a factor on how fast air can be suctioned in minutes. Some pumps can suction up to 6000 cubic feet per minute. Vacuum pump output, along with engine displacement determines this figure and how quickly it can get a job done.
Making the Best Selection
Choosing the biggest holding tank, largest engine, or strongest vacuum pump isn’t the only criteria for choosing a septic truck. Many times, a smaller size works better than bigger ones; finding the right choice means matching to job site requirements. Consider the following when choosing an appropriate truck size.
- Road Weight Restrictions – Most public roads have weight restrictions imposed to promote road safety and prevent road damage caused by heavy truck weight. Before buying a septic truck, determine the legal load limit in the primary driven area and be sure that the truck weight is well under the legal weight.
- Content per Load – The amount that can be collected per load varies depending upon septic truck size; so it is important to know average load size and be sure the holding capacity is enough for several uploads before requiring disposal. This is important as it can lower the number of trips to the treatment or disposal facility and will ensure there is enough room inside the holding tank to complete the job.
- Driveway Size – Collecting septic waste often requires a truck to be on a driveway to extend the suction line to where it is needed. The length and width of the truck must easily fit onto an average driveway which may require a light weight vehicle that will not damage the thin cement on most driveways.
In summary, successfully purchasing a septic truck for sale will require careful consideration as of average job site requirements. Hopefully this article has provided helpful information regarding the components that determine the size, load weight, and pumping capacity in order to select the appropriate size!
