Abstract

PURPOSE: To provide operating device for the excavator/loader equipped with a bucket adjustable at varying position in accordance with the inclination angle of arm under a design to enable deformation of parallelogram formed by 4-joint parallel-link mechanism according to necessity.
CONSTITUTION: A parallelogram of 4-joint parallel-link mechanism constituted by boom 9, arm 13, bucket cylinder 25 and bucket 18, is made variable by providing displacement lever 11 and position control member 29 which inclines the former at an optional angle. The bucket is automatically changed from an excavation position to a loading position by adjusting deformation volume of the afore-mentioned parallelogram, depending on operation requirements.
