Description

Tipping Trailer

FIELD OF THE INVENTION

This invention relates to tipping trailer for carrying and discharging bulk or particulate material.

BACKGROUND OF THE INVENTION

It is known to provide tipping trailer comprising a trough or bucket like load carrying body mounted on a wheels chassis having a draw bar to permit the trailer to be coupled to a towing vehicle, such as a tractor, wherein the load carrying body is pivotally attached to the chassis to allow the body to be tilted rearwardly to facilitate unloading of the trailer via a rear door of the body. Such tipping trailers are commonly used to transport bulk material, such as stone, gravel or sand. A problem with such known tipping trailers is that the driver of the towing vehicle cannot easily see the material as it is discharged from the load carrying body as it is tilted.

It is also known to provide stone cart trailers, wherein a load carrying body, typically in the form of a hopper, is fixedly mounted on a chassis of the trailer, the body being adapted to discharge material from a lower discharge opening at a bottom end of the hopper onto a transversely extending conveyor mounted beneath the hopper. While the driver can better see material as it is discharged from such hoppers, the shape of the hopper limits the capacity of the trailer.

An object of the present invention is to provide an improved tipping trailer which overcomes the disadvantages of the prior art.

Each of said first and second pivotal attachments may comprise a pivot axis extending transverse to the chassis.

In a preferred embodiment a conveyor is mounted on the chassis at or adjacent the front end of the load carrying body, said conveyor being adapted to receive material from said load carrying body when tilted forwardly with respect to the chassis and to convey said material to a discharge location to one side of the chassis. The conveyor may comprise a belt conveyer extending transverse to the chassis.

The load carrying body may include a discharge opening in or adjacent a bottom wall thereof through which material may be discharged onto said conveyor when the load carrying body is tilted forwardly with respect to the chassis.

Each of said first and second pivot attachments may be provided with a respective actuating means for selectively engaging and releasing each of said first and second pivot attachments.

One or more rams may be provided for tilting the load carrying body with respect to the chassis. Said one or more rams preferably act between the chassis at a first location thereon and the load carrying body at a first location on the load carrying body when the load carrying body is to be tilted forwardly and a second location on the load carrying body when the load carrying body it to be tilted rearwardly. An actuating means may be provided for moving the point at which the one or more rams acts upon the load carrying body between said first and second locations thereon.
