AI Technical Summary

Problems solved by technology

Therefore, in many cases a fixed swing interlock may be too restrictive
Also, such machines measure sway as the machine body in relation to the axle, not in relation to the horizontal, so side slopes are not taken into account when considering stability

Embodiment Construction

[0083] figure 1 A side view of the working machine 100 is shown. In particular, working machine 100 is a telehandler. Working machine 100 includes a machine body 102, load handling equipment 104, and a cab 110 within which one or more controls for controlling working machine 100 and an operator of working machine 100 may be located.

[0084] Load handling device 104 is coupled to machine body 102 via pivot 106 . The load handling device 104 is rotatable about a pivot 106 such that the load handling device can be figure 1 Movement in the x-y plane shown. In this embodiment, the pivot 106 is positioned towards the rear of the machine body 102 of the working machine 100 .

[0085] In the illustrated embodiment, the load handling apparatus 104 includes a boom 116 having an implement 118 mounted to its free end. In particular, implement 118 is a pair of forks (in figure 1 only one fork is visible in ). The forks are adapted to support rigid cargo, such as one or more pallets...

Abstract

A controller for use with a working machine, the working machine comprising a machine body and a load handling device coupled to the machine body and movable relative to the machine body by a lift actuator and movable relative to a lateral reference orientation about a swing axis by a swing actuator, the controller is configured to receive: a signal representative of a position of the load handling device relative to the machine body or the longitudinal reference orientation, and a signal representative of the stability of the working machine; the controller is further configured to determine an allowable range of movement of the load handling device about the swing axis, and to issue a signal for use by an element of the work machine comprising the swing actuator; in response to the signal issued by the controller, the elements are configured to limit or prevent movement of the load handling device relative to the lateral reference orientation outside an allowable range of movement that depends on a signal representative of a position of the load handling device relative to the machine body or the longitudinal reference orientation and a signal representative of the stability of the working machine.

Description

technical field [0001] The present teachings relate to a controller for use with a working machine, and in particular to a controller for maintaining the stability of the working machine. Background technique [0002] Working machines are commonly used in construction, agriculture, and other industries to perform tasks that humans cannot perform or perform tasks faster than humans. Examples of work machines include, but are not limited to, excavators, backhoe loaders, telehandlers, tractors, loaders, and dumpers. [0003] Many working machines include movable load handling equipment, such as, for example, booms (booms) that include a load mutual for handling, transporting and / or excavating loads (e.g., soil, cargo, produce, etc.) The active structure (eg, fork, bucket, jaw, etc.), is hereinafter referred to as implement. For such working machines, the lateral stability of the working machine may be significantly reduced when the load handling device is moved to a position ...
