BODY LIFTING SPEED CONTROL DEVICE FOR DUMP TRUCK

摘要

PROBLEM TO BE SOLVED: To provide a body lifting speed control device for a dump truck capable of performing spreading with uniform spreading amount when spreaded by the dump truck. SOLUTION: A raising operation speed coefficient pattern generating means 130 of a controller 100 generates a speed pattern for controlling the raising speed of the body so that a delivery amount from the body during the raising operation of the body corresponding to a body angle detected by a body angle sensor 55. A multiplier 150 multiplies an output signal of the speed coefficient pattern generating means 130 by an operation signal of an operation lever 60 and outputs it to control the body raising speed.
