The invention relates to a work device having a body with an attachment arrangement to attach the work device to a set of booms of a work machine. A pair of jaws fitted to the body includes two jaws arranged to form a grab. A first jaw is fixed to the body and a second jaw is pivoted rotatably to the body to open and close the grab. The rotatable jaw is arranged to be acted on by a hydraulic actuator, to open and close the grab. Between the hydraulic actuator and the rotatable jaw is a wide-angle pivot setup. An arm mechanism, equipped with two pivots fitted to a jaw arm is arranged to belong to the wide-angle pivot setup. In addition, the wide-angle pivot setup is arranged to include a rotatable lever arm fitted between the jaw arm and the body. The rotation angle of the movement created in the rotatable jaw by the wide-angle pivot setup has a magnitude of more than 120°.

Attachments for excavators and the like for improved gripping, handling, and processing of materials and debris are provided having one or more work surfaces to provide enhanced material handling characteristics.

A slurry wall grab has a hybrid drive in turn having at least one pulley block, at least one hydraulic actuator, and at least one energy store. The hydraulic actuator and the pulley block open and/or close a grab jaw of the slurry wall grab. The energy store can be charged by actuating the pulley block.

A control system for an excavator, the excavator comprising a movable arm, a movable excavator thumb and a tiltrotator attached to the arm, the tiltrotator being arranged to hold an auxiliary tool which is rotatable and/or tiltable by means of the tiltrotator. The control system is arranged to control the tiltrotator to rotate and/or tilt the auxiliary tool between a plurality of first positions and at least one second position. The excavator thumb is movable between at least one rest position and a plurality of work positions. The auxiliary tool is arranged to cooperate with the excavator thumb when the auxiliary tool is positioned in any of the at least one second position and when the excavator thumb is positioned in any of the plurality of work positions. The control system comprises a first blocker arranged to block the movement of the excavator thumb when the auxiliary tool is positioned in any of the plurality of first positions.

The invention relates to a removable tool assembly for a backhoe digging apparatus of a construction equipment machine having spaced apart parallel first and second fastening pins, said removable tool assembly including an attachment mechanism for releasably attaching said removable tool assembly onto the backhoe digging apparatus, the attachment mechanism including:—a first attachment element having first receiving areas adapted to receive the first fastening pin, and—a second attachment element having second receiving areas adapted to receive the second fastening pin, wherein the second attachment element is movable relative to the first attachment element between a first position, in which the first and second fastening pins can be removed from the first and second receiving areas.
