MOVING DEVICE FOR COUNTERWEIGHT
An apparatus for moving a counterweight includes: an attachment (20) fixed to a frame (7) of a machine; a supporting member (40) that includes a supporting face (40a) for placing a counterweight (10) thereon when the counterweight is mounted on the machine; and a link mechanism (30) that moves the counterweight (10). The link mechanism (30) includes an arm (43) and a rotating cylinder (35) that rotates the arm (34). One end (34a) of the arm (34) is pivotally supported by the attachment (20) while the other end (34b) of the arm (34) is pivotally supported in the upper inner portion of a recess (12) of the counterweight (10). One end (35a) of the rotating cylinder (35) is pivotally supported by the attachment (20) while the other end (35b) of the rotating cylinder (35) is pivotally supported in the upper inner portion of the recess (12) of the counterweight (10). The supporting face (40a) is shaped so as to coincide with the arc locus drawn by a contact face (15c) arranged on the side of the counterweight (10), as the counterweight (10) moves. The contact face (15c) comes into contact with the supporting face (40) when the counterweight (10) is mounted on the machine. The apparatus has a simple structure that avoids interference between the counterweight and supporting member when the counterweight is moved.
