Application and Construction Analysis of Wire Rope for electric crane hoist

Application and Construction Analysis of Wire Rope for electric crane hoist：Steel wire rope is one of the important parts of electric crane hoist, it has high strength, good flexibility, light weight, smooth operation, very little sudden fracture, etc., which is widely used in crane hoisting mechanism, luffing agencies, It can also be used as a rotating mechanism. It is also used as a rope for a bundle of objects, a tension rope for a mast crane, a rope crane for a cable crane and an overhead cableway, a carrier rope.

       Due to lifting steel wire rope to have a high strength and toughness, so often use phosphorus, sulfur low quality carbon steel cold wire into the wire, in the process of repeated heat treatment and dialing to get used to adapt to the crane in the 1400 ~ 1700N / ㎜ ² strength between the diameter of 0.2 to 2.0 mm high-quality steel wire, and then twisted into the stock, and then a number of shares around the rope made of rope, rope is wrapped by the rope is flexible The mandrel acts as a support and fixed strand and can be used to store lubricating oil and increase the flexibility of the wire rope.

        According to the applicable different occasions, the core can be divided into the following:

(1) metal core: made of soft steel wire, can withstand high temperature and can withstand greater compressive stress, because of poor flexibility, only for high temperature or multi-layer winding occasions.

(2) a movement: commonly used to make oil made of hemp rope, but also the use of cotton core, due to flammable, not for high temperature occasions.

(3) asbestos core: made of asbestos rope, high temperature.

(4) synthetic fiber core: made of synthetic fiber, high strength.
