MONITORING ARRANGEMENT FOR A MULTI-ELEMENT BOOM

摘要

A monitoring arrangement for a multi-element boom (4) consist of a fixed inclinometer (14) that provides a reference signal and a further inclinometer (11-13) associated with each element (5-7) of the boom (4). The further inclinometers provide signals proportional to the angle of the boom element to the horizontal. A processor means uses the length of each boom element and the inclinometer signals to calculate the position of the end of the boom (7). The arrangement is usefully applied to backhoes by placing the processor means and fixed inclinometer in the cabin. A display provides a continuous indication to the operator of the position of the bucket of the backhoe.
