SWING CONTROL DEVICE FOR SWINGING HYDRAULIC SHOVEL

摘要

PROBLEM TO BE SOLVED: To provide a swing control device for a swinging hydraulic shovel enabling an operating machine to easily move to a digging position and enabling the shovel to easily assume an attitude for digging an offset groove. SOLUTION: The swing control device for the swinging hydraulic shovel including an upper structure 3 rotatably mounted on top of a lower structure 2 and driven to revolve by a revolution drive means 29 driving it according to the operation of a revolving operation means 32 and the operating machine 4 which is driven to swing by a swinging drive means 17 driving it according to the operation of a swinging operation means 30, includes a rotational angle detector 19 for detecting the rotational angleθof the upper structure 3; a display 44; and a controller 40 which computes the amount of offset of the rear end of the operating machine 4 in the horizontal direction of a vehicle body according to a rotational angle signalθinput from the rotational angle detector 19 and displays the result of the computation on the display 44.
