WIPO Patent Application WO/2010/098232
Kind Code:
A1
Abstract:
Ends of both an outer arm (41) and an inner arm (42) of a lift arm (4A) moved and bent in association with the movement of an outer arm (31) and an inner arm (32) of an X-shaped pantograph arm (3A) are connected to the X-shaped pantograph arm (3A) through rotation bearings. An electric cylinder (5) is vertically connected through a pin joint from a connection pin (62) to a center pin (61) of the pantograph arm (3A), said connection pin (62) connecting the outer arm (41) and the inner arm. Pull-side operation of a movement nut (52) of the electric cylinder (5) vertically lifts up the outer arm (31) and the inner arm (32) of the pantograph arm (3A) relative to the lift arm (4A).
