A tipper truck, also known as a dump truck, is used for transporting dumps(such as sand, gravel or demolition waste) for construction as well as coal. A typical dump truck is equipped with as open-box bed, which is hinged at the rear and equipped with hydraulic rams to lift the front, allowing the material in the bed to be deposited(dumped) on the ground behind the truck at the site of delivery.
Today, virtually all dump trucks operate by hydraulics and they come in a variety of configurations each designed to accomplish a specific task in the construction material supply chain.
A standard dump truck is a truck chassis with a dump body mounted to the frame. The bed is raised by a vertical hydraulic ram mounted under the front of the body, or a horizontal hydraulic ram and lever arrangement between the frame rails and the back of the bed is hinged at the back of truck. The tailgate cam be configured to swing up on top hinges(and sometimes also fold down on lower hinges), or it can be configured in the “High Lift Tailgate” format wherein pneumatic rams lift the gate open and up above the dump body.
A Semi trailer end dump truck is a tractor-trailer combination wherein the trailer itself contains the hydraulic hoist. The key advantage of a semi end dump is a large payload. A key disadvantage is that they are unstable when raised in the dumping position limiting their use in many applications where the dumping location is uneven or off level.
A transfer dump truck is a standard dump truck pulling a separate trailer with a movable cargo, which can also be loaded wit construction aggregate, gravel, sand, asphalt, klinkers, snow, wood chips, trip mix, etc.
