The wire rope electric hoist is generally used with a crane or a cantilever crane, and can also be used as a winch after transformation. Therefore, it is an essential machinery for improving labor efficiency and working conditions. So what types of steel wire ropes do electric hoists with different specifications and models need to be equipped with?
Different models and specifications of wire rope electric hoists should choose wire ropes that are suitable for their load and working environment. Generally speaking, the selection of steel wire ropes should consider the following aspects:
1. Load: The maximum bearing capacity of the steel wire rope should be greater than the load that the electric hoist needs to lift. At the same time, different diameter steel wire ropes should be selected based on the size of the load and the requirements of the working environment.
2. Working environment: Different steel wire ropes are selected according to the requirements of different working environments and conditions. For example, in environments with high temperature, humidity, or corrosive gas immersion, specially treated corrosion-resistant or high-temperature resistant steel wire ropes should be selected.
3. Usage requirements: The usage requirements of steel wire ropes include bending radius, turning radius, etc. Steel wire ropes that meet the usage requirements should be selected based on the actual use of electric hoists.
According to the international standard ISO2408, each specification of electric hoist should be equipped with corresponding specifications of steel wire ropes, as shown in the table below:
Electric hoist specifications | Wire rope specifications
--- | ---
0.25T | 6mm
0.5T | 8mm
1T | 11mm
2T | 16mm
3T | 20mm
5T | 24mm
The steel wire rope model used for electric hoists is generally 6 × 19S+FC、6 × 37+FC or 18 * 7 and 35W * 7.
