Common wire rope specifications for cranes include 6x19S, 6x19W, 6x25Fi, 6x26WS, and 6x36WS. The 6x19S (Seale) structure has thick outer wires and high wear resistance, suitable for harsh lifting environments. The 6x19W (Warrington) structure uses alternating wire sizes to strike a balance between flexibility and wear resistance.
The 6x25Fi (Filled Wire) structure is filled with wires between the strands, which has excellent flexibility and extrusion resistance, making it an ideal choice for multi-layer winding applications. 6x26WS (Warrington-Searle) wire ropes are well known for their good fatigue resistance and are widely used in mobile cranes and tower cranes due to their all-round performance.
Besides, 6x36WS wire ropes are highly flexible and have excellent fatigue resistance, making them the first choice for applications that require frequent bending, such as bridge cranes and gantry cranes.
Selecting the right wire rope depends on a variety of factors, including load weight, frequency of use and rope threading system. Regular inspections and proper maintenance are also essential to ensure safety and extend the life of the wire rope.
With the correct wire rope specifications, crane operations in construction, manufacturing, shipping and other industries can achieve greater reliability, efficiency and safety.
