    摘要： Device for a hydraulic hammer (1), in which there is a hydraulic impact system and a work point (2) for performing work, for preventing damage caused by ricocheting pieces. The device is formed of a shield (6) that can be lowered to the level of the work point particularly by hydraulic cylinders (7, 8). The shield (6) is formed of an essentially circular jacket, in which recycled materials, for example recycled vehicle tires, transport mats, or similar, are mostly used.

    摘要： An impact tool capable of improving durability of tool components and capable of reducing noise and vibration is provided. The impact tool includes a housing, a motor, a motion converting portion, an output portion, a power supply portion, a load detecting portion, and a control portion. The motor is disposed in the housing. The motion converting portion is configured to convert a rotating motion of the motor into a reciprocating motion. The output portion is configured to output the reciprocating motion of the motion converting portion as an impact force. The power supply portion is configured to supply a driving power to the motor. The load detecting portion is configured to detect a load imposed on the motor. The control portion is configured to control the power supply portion to increase the driving power supplied to the motor during a prescribed period when the load detected by the load detecting portion is larger than a prescribed value.

    摘要： It is an object of the invention to reduce noise caused by run-out of a tool bit in an impact tool. The representative impact tool according to the invention includes a tool holder 137 that houses a tool bit 119 in such a manner that the tool bit can linearly move in its axial direction, and a barrel 108 that is integrally connected to the tool holder 137 The impact tool further includes an elastic element 155 that is disposed between an inner circumferential surface of the tool holder 137 and an outer circumferential surface of the tool bit 119 in an end region of the tool bit 119 on the barrel side and connected in close contact with the tool holder 137 and the tool bit 119 over a predetermined length of the tool bit 119 in the axial direction. The elastic element 155 applies a biasing force to prevent a run-out of the tool bit 119 in a direction transverse to the axial direction. Further, an intermediate element 145 comes in point contact with the tool bit 119 on its axial center line.

    摘要： A hydraulic breaking hammer (10) has a machine housing (11) in which a percussion motor (15) which includes a reciprocatingly movable percussion piston (17) delivers impacts to a breaking tool (13) in the front of the machine housing (11). The machine housing (11) is carried by a surrounding carrier support (18) via intermediate walls (24, 25, 26). The carrier support has the form of a shell (18) which is attached at the rear adjacent connecting devices (19), to a carrier, such as a hydraulic digging machine which aligns the machine housing (11) while the manner (10) is at work. The machine housing (11) is constructed without joints in its axial direction along the length of the housing and includes a guide passage (21) in which a percussion motor (15) is carried, this percussion motor having the form of an insert cartridge which can be clamped from the rear. The shell (18), the intermediate walls (24, 25, 26) and the machine housing (11) are all combined in a single one-piece metal casting and the space between the shell (18) and the machine housing (11) is filled with a sound-damping material which adheres to the housing (11) and surrounding parts. Hydraulic fluid communication with the percussion motor cartridge (15) is effected through annular grooves (44', 45', 46') provided in the guide passage (21).
