ABSTRACT:
An improved arrangement for gripping objects is disclosed which is particularly suited for embodiment in association with an excavator having a hydraulic hammer. The arrangement includes a gripping arm assembly operatively associated with the hydraulic hammer, including a gripping arm selectively movable with respect to the hammer. The arrangement can further include a detachably mountable clamping arm assembly adapted to be attached to the dipper arm of the excavator. The gripping arm and clamping arm assemblies are adapted to cooperate with each other with a claw-like working action to facilitate gripping of objects, such as material broken with the hydraulic hammer.
