Cross winding is reduced to approximately 20% of the circumference of the drum, and 80% remains parallel to the flanges in the inner layer rope groove. This parallel grooving evenly distributes the load between the individual layers and has been shown to increase substantially – by more than 500%, tests have shown – the life of the wire rope.
In manufacturing or mechanical engineering a groove is a long and narrow indentation built into a material, generally for the purpose of allowing another material or part to move within the groove and be guided by it.
Steel wire rope (right hand lang lay) Wire rope is composed of as few as two solid, metal wires twisted into a helix that forms a composite rope, in a pattern known as laid rope. Larger diameter wire rope consists of multiple strands of such laid rope in a pattern known as cable laid. Manufactured using an industrial machine known as a strander ...
It makes wire rope for bridges, cranes, elevators and mine shafts. It claims to be the only company in the world that makes wire rope from hot rolled steel.A brand of its wire rope is called Dyform; Dyform was introduced in the late 1960s as a seven-wire tendon for prestressed concrete construction.
Wire drawing is a metalworking process used to reduce the cross-section of a wire by pulling the wire through one or more dies. There are many applications for wire drawing, including electrical wiring, cables, tension-loaded structural components, springs, paper clips, spokes for wheels, and stringed musical instruments.
A cable grip is a device for propelling a vehicle by attaching to a wire rope (called a haul rope) running at a (relatively) constant speed. The vehicle may be suspended from the cable, as in the case of aerial lifts such as a gondola lift ( télécabine ), may be guided by rails , as in a cable traction railway , or may be self-guiding, as in ...
The lacing begins and ends with a whipping or other knot to secure the free ends. Wraps are spaced relative to the overall harness diameter to maintain the wiring in a tight, neat bundle, and the ends are then neatly trimmed. In addition to continuous or running lacing, there are a variety of lacing patterns used in different circumstances.
A marlinspike is used in working with wire rope, natural and synthetic lines, may be used to open shackles, and is made of metal. A fid is used to hold open knots and holes in canvas, and to separate the "lays" (or strands) of synthetic or natural rope for splicing. A variation of the fid, the gripfid, is used for ply-split braiding. The ...
