A contractor"s dump is similar to a typical flatbed with brief (12- come 24-inch) hard sides the fold down to develop unfettered accessibility to fill the body.

Whether hauling loose granular materials, such as topsoil or sand, or huge chunks of building and construction debris, dump body trucks equip a crew to unload cargo quickly, with tiny effort, and move on come the next job.

The dump functionality eliminates the need to manually unload the truck, reducing labor time (and costs), i m sorry preserves much more profit for each job. V a simple push that a button, the dump body tilts either towards the behind or side of the truck, leveraging gravity (instead of manual labor) to to water the payload straight into a dumpster or top top the ground.

However, in spite of all the promise of boosted productivity, if one of two people the chassis or dump body is not correctly equipped to manage the load, expense savings will vanish as result of premature maintain issues and also greater risks to employee safety. Given that light- and medium-duty dump van (up to course 7) price as much as $40,000-$70,000 per unit to acquisition (depending on dump human body type, material, and capabilities), the stakes room high because that fleet managers to gain the spec right.

So, just how should a dump body be spec'd to tackle the job? below are seven inquiries to guide the process.

1. HowWill the truck be Used?

Will the fleet usage the dump human body truck because that a specific purpose, such together hauling asphalt? Or walk it need a more flexible dump the serves many purposes? The answers to these questions will assist determine what form of dump ideal fits the application.

Here room four usual dump body types built for course 3 through class 7 trucks:

Flatbed/platform dumps are mostly flatbed body that administer the alternative for use as a recording body as soon as needed. For applications that usage the dump function on occasion, the flatbed intake is a low-cost alternative that offers flexibility.Conventional dumps are developed with hard stationary sides, welded come the body, and also primarily provided to haul and also dump loosened granular materials such as dirt, sand, gravel, etc.Contractor dumps are similar to flatbeds with brief (12-24 inch) hard sides the fold under to create unfettered access to fill the body. The sides come with a groove that allows users to include a board to do the political parties a few inches higher when one application calls for extra height. The fleet deserve to use a contractor dump to haul a broad range of materials, such as loosened dirt and also sand, or huge chunks that concrete debris.Landscape dumps can be configured in several various ways. Some landscape dumps have actually solid sides approximately 12-24 inches, with metal mesh adding several inch in height. This "hybrid" solid-mesh next configuration permits hauling loose materials (such as topsoil and also mulch) in ~ the bottom that the body and larger branches and brush above that. Options for swing-open rear and side gateways are additionally available.

2. Just how Much weight is the best Load?

This answer identify what size truck chassis is required for the job.

For example, come haul 5 cubic yards the sand, weighing 2,700 lbs. Per cubic yard, the full payload within the human body is 13,500 lbs. This would need at least a class 6 through course 7 van chassis, relying on the weight of the body and also other tools installed on the truck.

That's assuming the sand is dry. If the is wet, it deserve to weigh as lot as 3,300 lbs. Per cubic yard. Therefore, the same amount that sand (five cubic yards) that's wet in ~ 3,300 lbs. Every cubic yard would raise the payload need to 16,500 lbs. That's a 3,200-lb. Distinction from dry sand, which might require a bigger truck.

Once the preferably payload is estimated, variable a buffer into the calculations come cover any type of surprises. Then select a chassis that will handle the load.

3. What dimension Dump Body?

When analyzing contractor, landscape, or flatbed dumps, think in regards to length, width, and also height of political parties (if applicable). Because that example, the spec may be a 12-ft. Flatbed dump, 96 inches broad with 24-inch stake rack sides.

Since standard dumps are manufactured with the sides, tailgate, and floor fused together to type a solitary unit, their capacities space spec'd, no in length, height or width, but in regards to cubic yards. A typical dump body, for example, might be described as a "2-yard dump" or "5-yard dump."

4. Steel, Stainless Steel, or Aluminum dump Body?

Factors the drive this decision are cost, corrosion resistance, and weight. Stole is commonly the lower expense material and also is well-suited for daily heavy-duty usage. Because that corrosion resistance, the benefit goes come stainless steel and aluminum. In terms of weight, aluminum is the lightest the the three materials, improving fuel economy and also payload capacity, however is usually not recommended for harsh, heavy-duty use.

5. Electric or PTO Hoist?

Positioned between the rear axle and earlier of the cab, the hoist is powered either by the van battery (electric hoist) or the engine (PTO hoist) come lift the recording body turn off the van frame. Which type of hoist works best for one application?

For lighter duty (Class 3 through course 5 truck) applications or because that occasional use, many body manufacturers introduce an electrical hoist. Because the electric hoist is it is provided by the truck battery, it allows users to revolve off the engine once operating the dump, supplying fuel economy and environmental benefits.

For heavier-duty applications, which call for a bigger class 6 and also Class 7 van chassis, the power-takeoff (PTO) hoist is an ext common. Since the PTO hoist is driven by the truck engine, the gains greater power and also durability in handling heavy loads. The downside, however, is that the driver must keep the engine to run to run the recording body, which eats into the unit's fuel economy.

Consult the body agency on which hoist best matches the desired load and also dump consumption requirements.


When examining contractor, landscape, or flatbed dumps, think in terms of length, width, and also height of political parties (if applicable). For example, the spec may be a 12-ft. Flatbed dump, 96 inches broad with 24-inch stake rack sides.

6. Solitary or Multi-directional Hoist?

Most dumps use a single direction hoist the lifts the top end of the body to dump toward the rear. However, part body suppliers offer a multi-directional hoist that offers the choice to dump toward both the rear and also the side. This next dump capability enables usage of the dump duty without having to unhook and re-hook a trailer, i m sorry saves significant time and hassle.

7. Options to Optimize a dump Body's Performance

Consider the adhering to four options and asking the human body manufacturer for a listing that options certain to your offerings.

Cab shield. Stretches over the optimal of the cab indigenous the prior bulkhead that the dump body, protecting the cab indigenous damage. Cab shields come in a variety of sizes to cover one-fourth to fifty percent or even an ext of the cab.Tarp. Supplied to keep loosened material (such as gravel and crushed rock) from flying out of the bed and also onto the highway, causing damages to other vehicles. Tarps have the right to be manual or electric. What cd driver decision is cost and also convenience. If the budget plan requires a reduced priced option, go through manual. For higher convenience and also efficiency, spec electric.Underbody toolboxes. Linked to the structure under the recording body, these toolboxes for sure equipment and also tools native the facets or theft, without taking up extra cargo an are on the body. Underbody toolboxes come in range of dimensions and a an option of stole or aluminum. The differences between the two space price and also weight. Steel toolboxes cost less if the aluminum boxes sweet less and offer better protection versus corrosion.

Application-specific options. In the landscape industry, because that example, part body suppliers offer the option of a removable dovetail the connects to the behind of the intake body. This way, a see crew can lower the ramp ~ above the dovetail and drive their mowers and also other equipment onto the dump platform. Then once the crew needs the dump duty to unloading brush and other lawn debris, they deserve to detach and also roll away the dovetail. This conserves the landscape company from purchasing two trucks - one to transport equipment and also another come dump debris - once one truck deserve to perform both functions.
