Abstract

PURPOSE: To protect a wire rope from damages by finding a hanging load through computation of the moment acted by the weight of a boom bearing device and a boom at the pivoting fulcrum of the boom.
CONSTITUTION: Boom elevation angle signals are sent from a boom elevation detector 11 to an arithmetic unit 12 and the value obtained by dividing a moment acted at the pivoting fulcrum of a boom by the weight of a hanging load is outputted. Arithmetic unit 13 computes the moment acted by the tare of the boom at the pivoting fulcrum. An arithmetic unit 13 computes the moment acted by the boom bearing device at the pivoting fulcrum of the boom. An arithmetic unit 15 computes the weight of a hanging load by inputting the outputs outputted by each of the arithmetic units 12, 13, 14.
