An apparatus for connecting one or more guy wires to a down rod, the connector having first and second separable portions which form an aperture for receiving the down rod. At least one of the first or second portions includes at least one passage adapted for releasably receiving a portion of the guy wire. The guy wire may include an anchor, and the passage for receiving the guy wire may be adapted for capturing the anchor so as to preclude movement of the guy wire in a radial direction.

Various embodiments include a fastening unit for fastening a tendon to a system. The fastening unit comprises: a head with a first opening; a shaft with a second opening and an external thread; and a channel extending from the first opening along the head to the second opening at least partly along the shaft. The external thread and the channel in each case accommodate the tendon.

A face mask includes a body, two cords, and a retaining bead having a cord constraining passage. The body has upper and lower body edges spaced apart from one another by opposed left and right body edges. The body has left and right cord channels along the left and right body edges, respectively. Each cord extends from a first end, through a corresponding one of the left and right cord channels, to a second end. Each cord has first and second segments proximate the first and second ends, respectively. The first and second segments of each cord pass through the cord constraining passage. The cord constraining passage is sized to frictionally engage the first and second segments of each cord such that the retaining bead holds its position. The retaining bead is slidable along the first and second segments of each cord to advance the retaining bead toward the body.

The invention relates to rope gripping member for a rope gripping device, the rope gripping member comprising an elongated rope gripping face for being pressed against an elongated side face of an end section of a rope, the elongated rope gripping face having a longitudinal direction and a front edge and a rear edge; wherein tensile stiffness of the rope gripping member in longitudinal direction of the gripping face increases non-linearly with accelerating rate from the front edge towards the rear edge of the gripping face. The invention also relates to a rope gripping device, a rope terminal arrangement and a hoisting apparatus implementing the rope gripping member.

A cord lock for adjusting the length of a cord includes a main body with a through hole, in which a cord can be inserted. A friction member is blocked in the main body in such a manner that a portion of a tooth thereof narrows the gap of the through-hole in order to limit the sliding of the cord.

A clamping device (1), for coupling a sensor cable (2) to an electrical contact, has a circumferential, elastically deformable frame (3). The frame has an outer surface (5), an inner surface (6) facing an inner area (4), a first end face (7) and an opposite second end face (8). A contact device (9) is held at the frame and extends into the inner area. A counter-holding device (10), at the frame, has a counter-holding element (11). The contact device and the counter-holding device form a receiving space for holding the electrical contact in a holding position. A relative movement into a first released position is brought about by a pressing on both sides from the outside against the outer surface on a first frame axis (12). A second released position is provided by pressing on both sides against the frame outer surface on a second frame axis (13).

The bungee fastener has a tapered chute that accepts a locking slider. A channel forms an opening in a side of the body thereby allowing passage of the slider through the channel. A plurality of slider teeth along a portion of the slider within the tapered chute may lock onto a bungee when the slider is slid into a locked position. The slider moves along the channel, thereby selectively narrowing the tapered chute with the slider teeth as the slider is slid into the locked position and enlarging the tapered chute as the slider is slid into the unlocked position. The bungee fastener may include a single slider or a plurality of sliders.

A steering system includes a rod member, a housing, and a clamping member. The housing has a clamping slit and includes a first clamp-receiving portion and a second clamp-receiving portion that project so as to sandwich the clamping slit therebetween. The clamping member includes a fixed cam, a clamping shaft, a rotary cam, and a clamping lever. The fixed cam is fitted in the first clamp-receiving portion from an outer side of the first clamp-receiving portion. The fixed cam has a third through hole extending through the fixed cam coaxially with a first axis. The third through hole has a small diameter portion at a first portion close to the rotary cam and a large diameter portion having a diameter larger than a diameter of the small diameter portion at a second portion away from the rotary cam.

Cable gripper jaws and cable gripper jaw members having at least one removable, cable gripping surface insert. The gripper jaw member has a recess for receiving the insert and the insert can engage with the gripper member by means of a fixative and/or a mechanical engaging means, including mechanical interlocking means. The insert and gripper member can be of different materials, including metals of differing hardness ratings. The cable gripper jaws have utility in the cable gripping fields, including in the drilling and horizontal directional drilling industries, and as part of a method for pulling cable through space, including pulling cable through space in the pipe bursting and trenchless pipe replacement industries.
