Problems solved by technology

This sometimes results in cylinders being "oversized" for a particular application in order to ensure that it can lift the required load while ensuring that it will not buckle
However, choosing an oversized cylinder often means a slow tipping cycle, heavy cylinder weight, and the need for a large oil tank

Embodiment Construction

[0030] figure 1 and2 Shown is a dump truck 1 , sometimes called a dump truck, comprising a tractor 2 and a trailer 4 . The trailer 4 has a trailer chassis or frame 6 and a tipper body 8 is pivotally mounted to the trailer chassis or frame. A tipper truck body 8 is pivotally mounted to the chassis 6 about a transverse axis 10 positioned at the rear of the chassis 6 . The dump truck body 8 is in the form of a cuboidal container with an open top. The rear panel (or door) 12 of the tipper truck body 8 is hinged at its upper edge and can be locked and unlocked so that it can be opened to allow the contents of the tipper truck body 8 to empty. The multi-stage telescopic hydraulic cylinder 14 is configured to be pivotally attached at a lower end to the front of the chassis 6 and at an upper end to be pivotally attached to the front of the dump truck body 8 . Hydraulic cylinder 14 can extend (as figure 1 shown) to pivot the tipper truck body 8 about the axis 10 to a fully tipped p...

Abstract

A system for and method of operating a tipper comprising a tipper body pivotably movable with respect to a frame with a hydraulic cylinder disposed therebetween and actuatable to pivot the tipper body. A loading parameter relating to the load through the hydraulic cylinder is monitored during tipping. Based on at least the loading parameter, it is determined whether the hydraulic cylinder is at risk of buckling and, if it is determined that the hydraulic cylinder is at risk of buckling, an output is generated in response.

Description

technical field [0001] The present invention relates to methods and systems for operating dump trucks. In particular, the present invention relates to methods and systems for determining whether a hydraulic cylinder of a dump truck is at risk of buckling. Background technique [0002] Dump trucks (sometimes called dump trucks or dump trucks) are vehicles generally used in the construction industry to transport aggregates such as gravel or sand. A dump truck generally includes an engine, a cab and a trailer. A trailer typically has a trailer chassis or frame with a tipper body pivotally mounted thereto in the form of an open top cuboid container. A hydraulic cylinder is disposed between the frame and the dump truck body and is extendable to pivot the dump truck body to a tipped position in which a load is emptied from the body. The cylinder body can be retracted to put the dump truck body down. It should be appreciated that this is only one form of dump truck and that oth...
