Abstract:
A counterweight attachment and removal device which can connect lifting assemblies and a counterweight without precisely adjusting the construction machine position and the counterweight position, and which can attach the counterweight to adjust lateral direction. The device (18) includes a link (28) which is connected pivotally to the rear end of the construction machine, and a pair of coupling units (32, 32) which are connected to the leading end of the link (28). Each coupling unit (32) has a pair of coupling pieces (38, 40), a connecting pin (42) and a position adjustment member (44, 45). The coupling pieces (38, 40) extend from the link (28) and are able to tilt and move pivotally around the central axis (O). The connecting pin (42) is detachably connected to the extension ends between the connecting pieces (38, 40). Each adjustment member (44, 45) is disposed on the inner surface of the connecting piece (38, 40).
