Abstract: A control system for a hydraulic hammer is provided. The control system includes a sensing unit configured to sense position and rebound acceleration of a piston of the hydraulic hammer. The control system further includes an electronic control module (ECM) in communication with the sensing unit, and configured to generate signals based on the sensed position and rebound acceleration of the piston. The control system further includes a selection unit configured to allow an operator to select between a manual mode and an automatic mode. The control system further includes a valve in communication with the electronic control module (ECM). The valve being configured to be operated between a closed position and an open position based on the signals generated by the electronic control module (ECM) to selectively move the piston.

Abstract: A fork assembly for a lifting machine is provided. The fork assembly includes a fork base and a tine member. A first end of the fork base is attachable to the movable frame portion. A second end of the fork base extends outwardly from the first end. The fork base defines a lift surface, a first side surface, and a second side surface. The tine member defines a top portion, a first side portion, a second side portion, and a bottom portion. The bottom portion of the tine member defines a recess with a first engagement wall, a second engagement wall, and a third engagement wall. The tine member attains an interlocked position with the fork base, when the fork base is disposed within the recess of the tine member.

Abstract: A hammer tool assembly for a machine is provided. The hammer tool assembly includes a power cell, a tool, and a frame assembly. The frame assembly includes a first side plate and a second side plate. A set of paired blocks are coupled to an inner wall of the first and second side plates respectively. Each of the set of paired blocks includes a plurality of holes configured to receive dowel pins therein. A plurality of mechanical fasteners received through a plurality of openings at any one of the first and second side plates. The plurality of openings of each of the first and second side plates is coaxially aligned with corresponding holes in each of the set of paired blocks respectively. A plurality of mechanical fasteners passes through the aligned holes and extends through the plurality of openings provided at the other of the second and first side plates.
