  • Publication number: 20130240264
    Abstract: A permanent electrical contact applicable to the web of rails. The contact comprises a bush in electrically conductive material having a tubular stem suitable for inserting in a hole in the web of a rail, a flanged head radially widened compared to the stem and suitable for engaging in abutment with a portion surrounding the hole, and an axial through hole in which a punch can be inserted to expand the tubular stem radially and join a radially outer surface of the stem closely with the hole. At least a portion of the outer surface of the stem is substantially made of a first conductive metal and at least a portion of the flanged head is substantially made of a second conductive metal different from the first conductive metal.

  • Patent number: 8276430
    Abstract: A hydraulic pressing and/or cutting tool (1) comprises an electric motor (6), a converting mechanism (8) suitable to convert the rotary motion of the motor (9) to an oscillating translational motion, a hydraulic pump (11) suitable to carry out, in response to the oscillating translational motion, an increase in the pressure of a pressure fluid acting on an operating piston (12) such that the operating piston (12) is displaced, a stationary jaw (13) and a movable jaw (14) connected to the operating piston (12) such that, in response to the displacement of the operating piston (12), the movable jaw is displaced to the stationary jaw (13) to carry out pressing or cutting operations. The converting mechanism (8) comprises an epicycloidal gear (16) and a thrust unit (17) co-axial with the epicycloidal gear (16).

  • Patent number: 8042621
    Abstract: An impact mechanism (12) for an impact wrench comprises an anvil (8) with a middle portion (13), at least one abutment surface (14) radially protruding therefrom, which forms at least one abutment surface (15), a hammer (4) with an impact surface (16) suitable to give rotational pulses to the anvil (8) by the impact surface (16) hitting the abutment surface (15). The anvil (8) comprises a first connection area (17) connecting the abutment portion (14) to the middle portion (13) within the axial extension of the abutment surface (15) and the middle portion (13) and a reinforcement rib (18) axially arranged out of the abutment surfaces (15) that connects the abutment portion (14) to the middle portion (13) of the anvil (8), thereby forming a second connecting area.

  • Patent number: 7628220
    Abstract: An impact motorized wrench includes a tool-holder shaft arranged on a front side of the wrench and pivoting around a rotation axis, a rotary motion producing motor unit arranged on a rear side of the wrench opposite the front side and an operating member to operate the motor unit, a drive unit with a percussion mechanism being arranged between the motor unit and the tool-holder shaft. The motor unit, the drive unit and the percussion mechanism together form a base body of the wrench and the wrench includes two gripping handles attached to the base body, both being of elongated shape and transversally spaced apart relative to their longitudinal extensions. The handles define a common gripping plane tangential to both handles, which plane extends transversally to the rotation axis. The operating member is associated to one of the two handles.
