CONTROLLER FOR CONSTRUCTION MACHINE

摘要

PROBLEM TO BE SOLVED: To reduce a burden required for wiring by eliminating an additional installation of sensors in the front work machine section accompanied by the additional installation of a controller for a construction machine. SOLUTION: Angle sensors 41, 42 for the attitude detection for a work machine section provided on the front machine section 23 of a construction machine and a controller 43 for preventing front interference for the front interference prevention control based on the attitude data of the work machine section detected by the angle sensors 41, 42 are connected together by wires 44, 45. The controller 43 for front interference prevention is connected to a controller 46 for a shovel crane by a communication cable 47. The controller 46 for the shovel crane receives the work machine section attitude data possessed by the front interference prevention controller 43 when the hydraulic shovel is used as a shovel crane and restricts the movable range of the front work machine section 23 thereby preventing the overturning due to the enlargement of a slewing circle diameter of the front work machine section 23.
