The wire rope of the tower crane trolley is old and bad, and what is the reason why the wire rope of

The service life of the wire rope is short, find the reason from the following factors, 1Whether it is a qualified wire rope, the wire rope of a large factory is high but the quality management is in place, and the cheap one of a small factory may not have an engineer.

2.Whether there is frequent overload use, the service life is short if the load is large.

3.Whether the pulley is badly worn and scratches the wire rope.

4.Whether the pulley radius is too small.

5.Whether the wire rope is often oiled and relubricated.

6.Whether it is used in a humid environment, causing the wire rope to rust quickly.

China's annual output of 1.8 million tons of steel rope ranks first in the world, and the phosphated wire rope is the first time in the world to inhibit fretting fatigue and extend the service life (fatigue life) through surface treatment

1.Phosphate coated wire rope, the steel wire is phosphated by manganese or zinc-manganese, the wear-resistant, corrosion-resistant and rust-proof ability of the steel wire has jumped in an all-round way, and the service life is about 3 times that of the smooth wire rope with the same structure (pay attention to the difference between zinc-based phosphating for drawing and wear-resistant phosphating for rope making, although there are many enterprises in Tianjin, Jiangsu and other places, the supply is still tight, and the supply exceeds demand, which is an upgraded product of smooth wire rope, and can also replace the use of thin zinc galvanized wire rope).

2.Galvanized steel wire rope, hot-dip galvanized and electro-galvanized.

3.Stainless steel wire rope, 304 or 316 stainless steel.

4.Plastic-coated wire rope, on the basis of wire rope, the outer layer is coated with polyethylene or polypropylene.

5.The smooth wire rope will be completely eliminated by the phosphate coated wire rope.

Manganese phosphate coated wire rope is preferred in atmospheric environment, and hot-dip galvanized-phosphated double-coated wire rope is preferred in heavy corrosion environment.

Summary. Kiss! Hello, happy to answer your <>

The reason for the broken wire rope of the pro-tower crane trolley is as follows: 1. Overload: the load that the wire rope can bear is related to its material and cross-sectional area, before use, it must be calculated, and the wire rope that can withstand 10 tons of load must not exceed this load limit value divided by its corresponding safety factor; Second, the use of unqualified wire rope:

The bearing capacity of the wire rope that has been rusted or stiffened, and the surface is dry and free of oil stains is greatly reduced; 3. Improper use: When using the wire rope to lift heavy objects, the wire rope is not operated according to the regulations, or the lifting process is not lightly lifted and handled, and the speed is too fast, resulting in a large impact load. The wire rope is a spiral steel wire bundle that twists the steel wire with mechanical properties and geometric dimensions according to certain rules, and the wire rope is composed of steel wire, rope core and grease.

The wire rope is a rope that is first twisted into strands by multiple layers of steel wires, and then twisted into a spiral rope by a certain number of strands with the rope core as the center. In material handling machinery, it is used for lifting, pulling, tensioning and loading. The wire rope has high strength, light weight, stable work, not easy to break the whole root suddenly, and works reliably.

In 1834, the European Orubt invented the world's first wire rope (smooth wire rope), and the Tianjin No. 1 Wire Rope Factory established in 1939 was the first metal products enterprise in China. Hope mine can help you <>

Is the wire rope of the tower crane trolley because the trolley has no limit section?

Yes, yes.
