Description
While crane sheaves may be a relatively small piece of hardware, they play a crucial part in mechanical engineering and lifting equipment. They are used in tandem with a rope, belt, or cable to lift items with a crane. Essentially, a sheave is a wheel with an open groove that a rope or cable fits around so it can rotate around the exterior. One end of the cable is attached to an item that needs to be moved, while the other is attached to a fixed object, like the base of a crane. The cable smoothly moves over the wheel of the sheave as it is wound up on the fixed object, lifting the other object into the air.
Features
- Carburized and hardened sheave wheels last longer.
- Throat of wheel polishes under load, reducing friction between the wheel and the wire rope.
- High surface strength allows increased load capability.
- Excellent wear and strength characteristics.
- Include lightning holes to reduce weight.
- Improved compressive loading characteristics in elevated temperature environments.
