Choosing the right dump truck is not an ordinary task. The selection process requires thorough consideration of some essential factors that will affect productivity levels and offer the best return on investment. One of the first things to consider is fuel efficiency and load capacity; however, a decision should not be solely based on those factors as the engine, chassis, transmission and other essential specifications must be carefully considered as well. Before looking for a dump truck, it is imperative to know about the various types available when deciding which specifications best meet the needs of a business and its valued customers.

Common Types

The main features of these vehicles include the hydraulically operated dump bed, cab and chassis. Along with these features are different configurations to match various types of hauling projects.

  • Standard – This is the most common type of hauling vehicle on the road. It features a chassis with dump body affixed to a rigid frame. The dump box is raised by the hydraulic ram, which is attached below the front end of the bulkhead. The Cvv shop back of the dumper is hinged at the end portion of the chassis frame, while the tailgate can be configured as either swing-through or high-lift with pneumatic rams. Typically, a dual-axle can carry ten tons of loose material, while the triple-axle can haul up to fifteen tons. A single-axle set-up can only hold approximately three tons of sand, soil or gravel. Common configurations include six-wheelers and ten-wheelers that are used for construction projects.
  • Transfer – This is a modification from the standard set-up with a trailer combination. It increases payload capacity because of the additional aggregate box. Transfer configurations may have one or two additional boxes depending on the location. The triple transfer can carry approximately one hundred forty-two tons, provided it has a special use permit due to its collective gross vehicular weight.
  • Truck and Pup – This is a new design and modification of the transfer truck. Although it has a similar function, the additional aggregate box has the capacity to be tilted or raised because of the separate built-in hydraulic ram. The additional aggregate box of the original transfer device is different because it only rolls-off of the trailer through the use of an electric motor or pneumatic hoist.
  • Semi-Trailer End Dump – This type of design commonly consists of a tractor with three axles pulling a trailer with two axles and is ideal for rapid unloading. It does lack stability in some applications when the ground is unstable.

Purchase Considerations

It is fairly common to think of mileage, price, acceleration capacity, dump volume, horse power and torque when buying a truck. There are also other key factors to be given attention, including the Gross Axle Weight Rating (GAWR). Another essential factor to consider is the box length and type. The semi-circular box type is good for hauling loose material, while the square type is ideal for large volumes of loose or solid material the same length as the dumper.
