Abstract: Systems and methods can include stretching a stud of a hammer assembly by tightening, according to a preset amount, a plurality of fasteners, which can extend from a first end surface and/or a second end surface of a first nut threadedly coupled to the stud, against an upper surface of a body of the hammer assembly. The fasteners and the first nut can provide a clamping load for the stud upon completion of the tightening. The systems and methods can also include, after the stretching, tightening a second nut, which can be threadedly connected to the stud, toward a seat formed in the body of the hammer assembly; and further tightening the second nut, against the seat. The systems and methods can further include transferring the clamping load from the fasteners and first nut to the second nut.

Abstract: A dust suppression system for a demolition hammer is disclosed. The dust suppression system may have a water hose routed within a power cell of the demolition hammer, and a connector channel internal of the walls of a front head of the demolition hammer. The water hose may be utilized to deliver water from outside of the demolition hammer to a connection valve on a top end of the front head, and the internal connector channel may deliver water from the connection valve to one or more nozzles located at a bottom end of the front head.

Abstract: An example bushing of a hydraulic hammer tool includes a bulk region and an inner region. The inner region has a relatively greater hardness than the bulk region. The inner region may also be compressively stressed, while the bulk region may have tensile stress. The stress and/or hardness profile of the bushing may enhance its resistance to wear and galling defects when a hammer of the hydraulic hammer tool is held in alignment by the bushing. The bulk region of the bushing may be relatively soft, resulting in the bushing having a relatively high level of toughness. The bushing may be formed using medium to high carbon steel by rough forming the bushing, hardening the bushing, tempering the bushing, induction hardening the inner region of the bushing, and then quenching the inner region.

Abstract: A lubrication system for a hydraulic hammer includes a body defining a recess in fluid communication with a lubricant inlet and a lubricant outlet. A sleeve, located co-axially within the recess, defines a stepped tubular cavity having first and second portions. The sleeve also defines inlet and outlet ports extending from an outer surface to an inner surface of the sleeve. A piston, located partly within the recess and the first portion of the stepped tubular cavity respectively, has a tubular cavity co-axial with the stepped tubular cavity. A spool is located partly within the tubular cavity and the second portion of the stepped tubular cavity respectively. The spool co-operates with the inlet and outlet ports of the sleeve for reciprocally moving the piston in relation to the body so that lubricant from the lubricant inlet is delivered by the piston to the lubricant outlet via the recess.

Abstract: A lubrication system including a drive fluid chamber and a lubricant chamber. A first movable member is movable from a first position to a second position within the drive fluid chamber in response to drive fluid pressure acting on the first movable member. A second movable member is movable between a first position and a second position within the lubricant chamber and is operatively coupled to the first movable member. A biasing member is positioned to bias the first movable member toward the first position. A relief valve is associated with the first movable member and, when the relief valve in an open state, the drive fluid pressure acting on the first movable member is reduced such that the biasing member moves the first movable member to the first position within the drive fluid chamber.
