The wire rope hoist rope core are there?
For increased low headroom wire rope hoist wire rope around and elasticity, and be able to better lubrication, wire rope lubrication is not good, will increase with the pulley, the frictional resistance of the roll. The center of the wire rope has a rope core, or there was a cord in the shares of each of the wire rope.
There are four common cord:
(1) Movement: to do rope core made of cotton twist rope or shares, the movement rope soft and easy to bend, wire rope pinched in the process of using the stored cord oil oozed lubrication rope, the wire rope heat-resistant, flame retardant bad, does not apply to the high-temperature environment, can not be subject to the weight.
(2) fiber core: natural or synthetic fibers twist made of rope or shares do rope core, this wire rope is not used in high temperature environment, can not be subject to the weight.
(3) asbestos core: Asbestos twist made of rope or shares cord, the asbestos core rope soft and easy to bend, wire rope cord pinched during use stored oil leaking can lubricate wire rope, such wire rope oil oozing pinched during use, cord storage can lubricate wire rope, the rope suitable for metallurgical and other high-temperature environment. But not by the weight.
(4) metal core: made of mild steel soft wire rope or shares over the cord, this wire rope is resistant to high temperatures and withstand greater lateral load, suitable for high-temperature environments or multilayer wound occasions, but the price is relatively high .
