COMPLETE GUIDE TO DUMP TRUCKS

WHAT IS a DUMP TRICK?

A dump truck is also known as a tipper truck or dump truck. It is used to transport finer materials for construction, such as gravel or demolition debris. A dump truck is usually equipped with an open-box box bed that is hinged at its rear and equipped to lift the front. This allows the material in the bed to “dump” on the ground behind it at the delivery site.

This article will cover the various types of dump trucks, brands of dump trucks, how to purchase a dump truck, and how to finance it.

TYPES

There are many types of dump trucks that can be used for almost any purpose. Here is a list of all the types.

STANDARD DUMP TRICK

A standard dump truck is a truck frame with a dump body attached to it. The bed can be raised using a vertical hydraulic pump under the body, or a horizontal hydraulic pump and lever arrangement between frame rails. At the truck’s back, the bed is hinged.

You can have the tailgate swing open on top hinges and sometimes fold down on lower hinges. Or you can make it lift up with pneumatic rams.

SEMITRAILER END-DUMP TRUCK

Semi-end dumps are a tractor-trailer combination in which the trailer contains the hydraulic hoist. A semi dump is a tractor-trailer combination that pulls a trailer with two tires and a 3-axle tractor in the US.

A semi-end dump has a large payload, which is its main advantage. They are unstable when raised in the dump position, which limits their use in applications where the dumping area is uneven or not level.

TRANSFER TRUCK

A transfer dump truck is a dump truck that pulls a trailer and carries a movable cargo box. This container can be loaded with construction aggregate, gravel or asphalt, snow, blinkers, wood chips, triple mixture, etc.

The trailer’s second aggregate container (“B”) is powered by either an electric motor, a hydraulic motor, or a pneumatic motor. It rides on small wheels and is supported by rails that run from the trailer’s frame to the empty main dump container (“A”) box. This increases payload capacity while maintaining the truck’s maneuverability. Due to restrictions on weight on the highways, transfer dump trucks are most commonly seen in the western United States.

SUPER DUMP TRUCK

Super dump trucks are straight dump trucks equipped with trailing axles. This is a load-bearing, liftable axle that can be rated up to 13,000 pounds. The trailing axle is located 11-13 feet behind the rear tandem and stretches the outer “bridge”, the distance between the last axles to the maximum length.

This will increase the allowed gross weight under the federal bridge formula. It sets standards for truck sizes and weight. The Superdumps can weigh up to 80,000 pounds depending on their length and axle configuration. GVW and can carry 26 short tons or more of payload.

The truck’s rear axle is cleared by two hydraulic arms when it is empty.

SEMITRAILER BOTTOM

Semi-bottom dump, or belly dump, is a 3-axle tractor that pulls a 2-axle trailer and has a clamshell-type dump gate in its belly.

Semi-bottom dumps have the advantage of being able to lay material in windrows, which is a linear heap. A semi-bottom dump can also be used in reverse, unlike double or triple-trailer configurations.

These trailers can be either the windrow type as shown in the photograph or the cross-spread type. The gate opens from the front to the rear and not left and right. Cross-spread gates will spread the cereal grains evenly across the trailer’s width.

The windrow gate, on the other hand, leaves a pile in its middle. Cross-spread gate on the other hand tends to jam and may not be able to work well with coarse materials.

DOUBLE AND TRIPLE TRAILER BOOT DUMP TRUCK

A 2-axle tractor pulls a single-axle semitrailer with an additional trailer or two full trailers in triple dumps. These dump trucks enable the driver to lay material into windrows from the truck’s cab without having to stop the truck.

The biggest problem is backing triple and double units.

SIDE DUMP TRACK

Side dump trucks, also known as SDT, consist of a tractor and a semi-trailer with a 2-axle axle. The dump body is tilted onto its side by hydraulic rams, which spill the material onto either the right or left side of the trailer. An SDT is a great option because it can load more weight and allows for quick unloading.

It is also almost impervious to being upset or tipping while dumping unlike semi-end dumps, which are more prone to tipping. If dumping is stopped early, it is highly probable that the side dump trailer will tip over.

If the pile is too large to cover the wheels of the trailer, it can cause the side dump to become stuck.

Trailers that dump at an appropriate angle (e.g., 50 degrees) avoid any potential problems with the trailer’s wheels. They dump their loads farther to the side of the truck. In some cases, there is enough clearance for the load to pass between the trailer and the trailer.

WINTER SERVICE VESCULES

Many winter service vehicles are built on dump trucks. This allows for ballast to be placed to help the truck weigh down, or to store sodium or calcium chloride salts to spread on snow or ice-covered surfaces. Plowing is a very dangerous service that requires heavy-duty trucks.

ROLL-OFF TRUCKS

The Roll-off is equipped with a hoist and a subframe. However, no one can carry removable containers. The container is placed on the ground and then pulled onto the truck using a winch or cable. After the truck has been loaded, the empty container is removed from the truck and taken to the dump site.

The hoist is raised, and the container slides down from the subframe to the ground. Rollers at the rear of the container allow for moving forward and backward until the front is lower to the ground.

These containers can be used for building debris and rubble, but they can also be used to transport rubbish compactors. The hook-lift system is more modern and does the same thing, except that it lowers and dumps the container using a boom arrangement.

OFF-HIGHWAY DUMP TRUCKS

Heavy construction equipment and off-highway trucks have little in common with highway dump trucks. These larger, off-highway trucks are used for heavy dirt hauling and mining.

There are two main types of articulating frames: the rigid frame and the articulating one. The mining industry and the machine manufacturers do not use the term “dump truck”. This vehicle is strictly off-road and should be called a “haul truck” in the United States.
