A low-PIM dual pipe clamp and associated mounting bracket for securing a first pipe transverse to a second pipe at a cellular base station antenna site. The dual pipe clamp accommodates a range of pipe diameters with lower PIM generation, cost, and weight characteristics compared to conventional dual pipe clamps traditionally used at cell sites. The low-PIM dual pipe clamp minimizes the number of parts to upper and lower mounting brackets connected by linear threaded rod connectors, such as bolts, avoiding the use of U-bolts known to create PIM interference in conventional designs. The dual pipe clamp secures first and second pipes against each other in transverse orientations (e.g., horizontal and vertical), as typically utilized to mount antennas at cellular base stations. Each mounting bracket includes first and second pipe restrainers that bias the first and second pipes against each other as the threaded rod connectors are tightened.

A coupling device includes two coaxial shafts, namely a tubular outer shaft and an inner shaft, capable of rotating about a reference axis; a wrap-around raceway formed on a first one of the coaxial shafts; an oblique raceway formed on the second coaxial shaft and a play take-up rail provided with a complementary raceway and movable relative to the second coaxial shaft parallel to a plane perpendicular to the reference axis. A row of balls is positioned to run parallel to the reference axis on the wrap-around raceway, the oblique raceway and the complementary raceway, to guide the two coaxial shafts relative to each other in translation.

Various embodiments illustrated herein disclose an axle lock assembly comprising a first plate with a first aperture, a second plate with a second aperture, a shaft, wherein the shaft is inserted through the first aperture and the second aperture and a bush. When the hushing is in contact with the first plate and the second plate, the bush creates a lateral force to move the first plate and the second plate in opposite directions to secure the shaft.

A clamp for internally coupling and decoupling two components can include a base fittable within an interior of at least one of two components to be coupled together. The clamp can also include an engagement member movably supported about the base. The engagement member can interface with and engage interior portions of the two components when in a coupled position separated from the interior portions of the two components when in a decoupled position. The clamp can further include a wedge movably supported about the base to facilitate movement of the engagement member between the coupled and the decoupled positions. In addition, the clamp can include a secure and release mechanism operable with the base and the wedge to alternately secure the wedge to maintain the engagement member in the coupled position and release the wedge to facilitate movement of the engagement member to the decoupled position.

A clamp and universal wedge clamp system is provided. The system includes a rigid clamp that is formed to define first and second arms that extend from opposite ends of a central member. The first and second arms each comprise a finger that extends inwardly toward the finger extending inwardly from the opposite arm, and at least one of the first and second arms comprising a slot defined through the arm along a portion of a length of the arm. A wedge extends through the slot, wherein the clamp and the wedge are collectively configured to removably retain a beam upon either one of a substantially cylindrical shoring post, or a substantially rectangular shoring post.

Connecting arrangement for a hydraulic cylinder having a cylinder housing and an extendable piston rod, at the free end of which a linkage lug for connection to a construction component is arranged, characterized in that the linkage lug is connected to the piston rod via a plug connection.

A locking arrangement for connecting and interlocking rods at a node within a framework includes connection rods and a central node bearing to be engaged from different directions by each of the connection rods at respective mounting ports through plugging each connection rod onto a respective mounting port. The central node bearing is configured with at least one locking element at each mounting port to be actuated between a locked state, in which the at least one locking element resides in an outward position and the respective connection rod plugged onto the respective mounting port is clutched to the central node bearing by the at least one locking element, and an unlocked locked state, in which the at least one locking element resides in an inward position and the respective connection rod is released from the central node bearing.

Provided is a wedge clamp for anchoring an end of a steel wire for further enhancement in workability upon use. A wedge clamp 1 for retaining a steel wire includes a first member 12 having a wedge shape and a second member 11 slidably fitting the first member 12 to restrain a steel wire by a pressure that generates based on the wedge shape of the first member 12, the wedge clamp 1 including an engaging portion (protrusion 124 and anchoring portion 113) enabling slidable fit between the first member 12 and the second member 11 while engaging the first member 12 and the second member 11.
