Title:
INTERFERENCE AVOIDING CONTROLLER FOR WORKING CONSTRUCTION MACHINE
Document Type and Number:
Japanese Patent JP3153192
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To continuously carry out a work while avoiding interference of a bucket with an attachment when the attachment approaches a cab during the work.
SOLUTION: An arm limit angle βLT is set on the basis of a real boom angle αact and a real offset angle γact input from a boom angle sensor 33 and an offset angle sensor 34. A real arm angle βact input from an arm angle sensor 35 is fed-back to the arm limit angle to obtain an angle deviation Δβ. A command is output to electromagnetic proportional pressure reducing values 24, 27 disposed in the driving circuit of a cylinder 12 for the arm on the basis of the angular deviation to automatically avoid the interference of the arm.
