The common five is destroyed by the wire rope hoist wire rope in use
Electric wire rope hoist, wire rope in the day-to-day use, the wire rope will eventually be repeated loads scrapped. Replacement of the scrapped wire rope electric hoist can continue to use, instead of the correct way to use make rope greatly shorten its life. Here I will introduce the wire rope in use generally encountered several undermine reason
1, fracture of the wire rope in use fierce impact the lead wire rope running overload, damage, localized wear or rope in serious rust, fatigue, speeding, slipping under the wire rope of one or a few shares of fracture.
, Wire rope twisted, bent, pull method is not correct, or incorrect drum winding wire rope sheave, fixed improper distortion, bending.
3, to enhance the process of relaxation caused by injury, frequent use of wire rope, the operation of the beam caused by bending wire rope Shengka Department, and lead wire fatigue and fracture.
, Wire rope damage in the lifting operation, improper use of wire rope in the lifting operation, causing damage or fatigue fracture.
5, wire rope the twist distance elongation or narrow, because the rope in the lifting operation often overloaded, squeezed steel core twist caused by elongation or out.
