Harbor Load and Unload Crane Steel Wire Rope

Introduction: Harbor Load and Unload Crane Steel Wire Rope is used for cranes for load and unload in harbors. Crane Steel Wire Rope is the pivotal part in every type of crane lifting work. Steel Wire Rope probably is the most frequently replace part of the lifting Equipment, but it is a critical component. There are several tips of choosing crane steel wire rope as following.

1) The crane steel wire rope is made of high strength steel drawn into filaments. The tensile strength from 1400 MPa to 2000 MPa, use high tensile strength wire rope can choose small rope diameter, then the pulley sheave and winch diameter. But the more higher tensile strength, the worse fatigue resistance will be.

2) Single strand crane steel wire rope has smooth surface and high steel-degree. It can be used as fixed cable. When the surface of wire rope using special Z-shape cross section wire, it will be quite smooth and this steel wire rope can be used as load bearing cable, which the trolley can run on.

3) The Steel Wire Rope for Crane with lifting pulley blocks, usually choose multi-strands, such as 6 strands and 8 strands.

4) Considering the wire rope diameter and lay direction, the linear contact lay has excellent quality and long life.

5) When the crane steel wire rope has to be worked in moisture or acid gas environment, galvanized steel wire rope is recommended, and stainless steel wire rope.

6) The breaking form of crane steel wire rope is worn or fatigue broken of wire. When the breaking or worn of a certain lay unit of wire exceeds the specified degree, the steel wire rope should be replaced.
