What is the calculation formula of wire rope?

The calculation formula of lifting weight of steel wire rope is theoretical weight of steel wire rope (kg)= diameter of steel wire rope * diameter of steel wire rope * calculation coefficient. Because of safety considerations in practical work, it must be divided by a safety factor of 4-8 times. Wire rope refers to a flexible rope twisted by multiple or multiple thin steel wires. The steel wire rope is made by twisting multiple layers of steel wires, and then twisted into a spiral rope with a certain number of strands around the rope core. In material handling machinery, it is used for lifting, traction, tensioning and bearing.

Selection of wire rope

Wire rope for hoisting can be 6X 19 type, and 6x37 type should be adopted, because the latter is easy to bend. When in use, it can be single, double or multi-person. The splicing of wire rope splicing joint is the most common way in lifting operation. When splicing joints are used for nooses at both ends of the wire rope, the length of splicing joints should not be less than 20 times of the direct length of the wire rope. In addition, there are tapered wedge sleeve connection, aluminum alloy sleeve compression connection, rope clamp connection and so on.
