The material selection for manufacturing rolled crane sheaves depends on the use environment and performance requirements, and usually includes: carbon steel (Q235, Q345), alloy steel (42Cr, 20Mn2), cast steel, cast iron (gray cast iron, ductile cast iron), stainless steel and aluminum alloy

1. The surface of the rope groove is smooth and wear-resistant, and can be heat treated to improve its hardness, thus extending the service life of the pulley

2. Reasonable structure, high strength, light weight, 40% lighter than cast pulleys of the same specification

3. Hot rolling process production is relatively simple, low energy consumption, high material utilization, low production cost

4. Stable performance, through the hot rolling process, you can better control the heat treatment process of the crane sheaves to ensure that the pulley has stable mechanical properties; It has good fatigue resistance and is suitable for long-term use.

We provide various types and specifications of pulley blocks, including single sheave crane block, double-wheel pulley block, multi-wheel pulley block, fixed shaft, movable shaft, etc. We offer products in different sizes and load-carrying capacities based on our customers’ needs and specific circumstances.
