摘要： A leveling device assembly for use with a hydraulic hammer is provided. The leveling device assembly comprises a control unit, a leveling sensor in communication with the control unit, and a laser generator in communication with the control unit. Additionally, the laser generator is configured to produce a first colored light beam and a second colored light beam different from the first colored light beam. The control unit is further configured to cause the laser generator to produce the first colored light beam when the leveling sensor indicates the hydraulic hammer is in a substantially vertical position and produce the second colored light beam when the leveling sensor indicates the hydraulic hammer is in a substantially non-vertical position.

摘要： A rock drilling machine equipped with an axial bearing having at least one axial piston for setting the axial position of a drill shank and for damping stress pulses returning from the rock. The axial bearing includes a module that is detachable in one piece from one installation direction. The axial bearing module includes all necessary seals, bearing surfaces, and a module frame. Supporting forces caused by the operation of the axial bearing are transmitted of support members in the module frame directly to the body of the rock drilling machine, which is a uniform piece at least at the axial bearing.

摘要： A fluid-operated percussion device (1) having a percussive piston (3), which alternately executes a work stroke and a return stroke due to the effect of a control. To avoid no-load strikes, in one embodiment of the percussion device (1), the percussive piston (3) is shut down if it has overshot the extended position occurring in normal operation (long- and/or short-stroke operation) by a predetermined distance in the work-stroke direction (arrow 3e) and reached a no-load-strike position. For this purpose, the interior (2d) of the work cylinder (2) that receives the percussive piston (3) additionally has a no-load-strike opening (20a), which is connected to the pressure line (8) of the percussion device (1) with an interposed safety element (21) that can be switched between an inoperative position and an operative position.

摘要： A unitary valve assembly for a fluid-activated, percussive paving breaker includes a valve chest having an outer sidewall forming an internal valve chamber, a sidewall within the internal chamber forming a valve bore, a reciprocal valve within the valve bore and a bottom plate permanently fastened to the outer sidewall. The inner sidewall forms a first annular, upstanding sealing seat for the valve, and the bottom plate forms a second annular, upstanding sealing seat for the valve. Passageways through the valve assembly are positioned so as to connect with high and low pressure chambers of a paving breaker, when the valve assembly is inserted into the paving breaker. For weight reduction, the valve assembly is made of acetal resin.

摘要： A hammer of the type having an impact tool driven by pressurized fluid has a hammer body portion with a closed rearward end and an open forward end and a piston longitudinally movably housed within the hammer body portion for striking a tool mounted at the open forward end of the hammer body portion, to thereby impact an object with the tool. The hammer has a fluid valve housed within the closed rearward end of the hammer body portion rearwardly of the piston and in communication with a source of high pressure fluid for driving the piston. The fluid valve has a valve body portion defining an interior chamber and a continuous exterior side wall, and a longitudinal opening in communication with the interior chamber. The valve body has a first body portion and second body portion which is identical to the first body portion and positioned longitudinally in relation thereto within the closed rearward end of the hammer body portion. The first valve body portion and the second valve body portion each have at least one open-sided transverse channel extending from the continuous, external side wall of the wall to the internal valve chamber to thereby simplify and facilitate manufacture of the valve body, and the longitudinal opening and the open-sided transverse channels permit access of pressurized fluid through the valve chamber between the closed rearward end of the hammer body portion and the piston to direct the flow of pressurized fluid entering the valve.

摘要： A pneumatic percussion tool includes a head valve device including first and second head valves disposed in the body and movable in response to the pressure variation in the head valve chamber. The first and second head valves are positioned at a first position for preventing communication between the main air chamber and the percussion piston chamber while permitting communication between the percussion piston chamber and the outside of the body and preventing communication between the head valve chamber and the outside of the body when the compressed air is introduced into the head valve chamber through the change-over valve. The first and second head valves are movable from the first position to a second position for permitting communication between the main air chamber and the percussion piston chamber while preventing communication between the percussion piston chamber and the outside of the body and between the head valve chamber and the outside of the body when the compressed air has been discharged to the outside through the change-over valve. The first and second head valves are movable relative to each other for permitting communication between the head valve chamber and the outside of the body and for preventing communication between the percussion piston chamber and the outside of the body during the movement from the first position to the second position.

摘要： The machine includes a reciprocating piston/hammer (10) assembly, which is constrained against rotation in the cylinder (8). This allows the cutting bit to apply concentrated action along a line, and thus is useful for cutting grooves. The cutting bars (40) are arranged in sequence to enter progressively deeper into the groove. Many bits are arranged side by side, for cutting parallel grooves simultaneously.

摘要： A pneumatic rock drill which has a pneumatic percussion unit with a piston which slidably engages the cylinder in which it reciprocates. Preferably clearances of less than less than about 0.00125 inches per inch of piston diameter and greater than about 0.00075 inches where clearances are diameter are maintained to assure a fluid film between the piston and the cylinder wall. The clearances are based on diameters. The piston of the pneumatic drill has at least one stem section which slidably engages a distributor.The rock drill has a pneumatic motor connected to the percussion unit and engages a distributor of the percussion unit. A air motor gear in the pneumatic motor is rotatably mounted on the distributor.The exhaust is employed to lubricate the bearings and gearing which turn the striker bar.
