Saipem's Castorone, the world's largest pipe laying vessel uses a wire rope that is 3,850m long and 152mm in diameter. It weighs 420t. The rope is pulled by capstan and stored on a massive Rema traction winches that feature the parallel grooving system, with an approximately back tension of 40t on the capstan.
A Gripple wire joiner is a device used to join and tension wire, to terminate and suspend wires and wire ropes, and also to support false ceilings, cable baskets, and similar items. They are manufactured in Sheffield, England by Gripple Ltd. [ 1 ] The name derives from the fact the device both "grips" and "pulls" wire.
A cable reel is a round, drum-shaped object such as a spool used to carry various types of electrical wires. [1] Cable reels, which can also be termed as drums, have been used for many years to transport electric cables, fiber optic cables [ 2 ] and wire products.
This is a vertical spool with a ratchet mechanism similar to a conventional winch, but with no crank handle or other form of drive. [7] The line is wrapped around the spool and can be tightened or reeled in by pulling the tail line. The winch takes the load once the pull is stopped with little operator tension needed to hold 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 ...
A turnbuckle, stretching screw or bottlescrew is a device for adjusting the tension or length of ropes, cables, tie rods, and other tensioning systems. It normally consists of two threaded eye bolts , one screwed into each end of a small metal frame, one with a conventional right-hand thread and the other with a left-hand thread.
A strain insulator is an electrical insulator that is designed to work in mechanical tension (strain), to withstand the pull of a suspended electrical wire or cable. They are used in overhead electrical wiring, to support radio antennas and overhead power lines. A strain insulator may be inserted between two lengths of wire to isolate them ...
A hydraulic riser tensioner consists of a hydraulic cylinder with sheaves at both sides. The cylinder is connected to a number of high-pressure gas bottles via a medium separator. A wire rope is rigged in the cylinder; one end is connected to the fixed part of the tensioner, the other end is connected to the riser. [1]
