Abstract

PURPOSE: To extend the working range of a construction equipment by a method wherein a swivel mechanism is installed between a working means and an arm so that the working means can work even in other planes than a vertical plane.
CONSTITUTION: With a directional control valve 34 changed over from a function position A to a function position B, a lock cylinder 33 is operated to release the lock of a swivel arm 17. Then, with a directional control valve 36 changed over from a neutral position to a function position A or B, hydraulic oil is fed into one of liquid chambers of a cylinder 20, and a piston 39 is moved to drive sprockets 22, 23. As a result, the arm 17 is rotated on the axis of an arm 12 through a spur gear 27, intermediate gear 30, spur gear 29, and bevel gears 28, 25, while a bucket 19 is rotated about the axis shaft line of the arm 12.
