Abstract

A control sleeve (46) rotates a front boom (5). A sensor (17) detects angular position of the boom. A controller (50) controls the motion of an arm (7) connected to the end of the boom, based on the output of sensor. The relationship of the boom motion and arm with reference to an end position (14a) is set by a setting unit such that a bucket (14) attached to the arm moves linearly.
