Product Description
In any lifting operation, the crane sheave is a component where failure is not an option. It operates under immense stress, guiding the wire rope that carries the load. A low-quality sheave not only poses a significant safety risk but also causes premature and costly wear on the wire rope itself.
Yile Machinery is a specialist manufacturer of high-integrity, forged steel sheaves engineered for the extreme demands of mobile cranes, overhead cranes, and other heavy lifting equipment.
While some low-cost pulleys are cast, critical lifting applications demand the superior strength and reliability of forged steel.
Enhanced Strength & Durability: The forging process refines the steel's grain structure, eliminating internal voids and creating a component that is significantly stronger and more resistant to fatigue and shock loads than a casting.
Increased Safety Factor: The predictable and uniform strength of a forged sheave provides a higher, more reliable safety factor, essential for personnel and equipment safety.
Longer Service Life: Forged sheaves offer superior resistance to cracking and failure, resulting in longer operational life and reduced maintenance downtime for your crane.
The interaction between the sheave groove and the wire rope is critical. Our manufacturing process focuses on protecting your wire rope investment and ensuring smooth operation.
Premium Material Selection: We begin with high-quality carbon and alloy steels such as C45, 35CrMo, and 42CrMo (AISI 4140) , selected for their strength and toughness.
Precision CNC Machining: The wire rope groove is CNC-machined to precise dimensions and a smooth surface finish. A proper groove profile provides optimal support for the wire rope, preventing it from flattening or being damaged under load.
Groove Surface Hardening: To maximize wear resistance, the sheave's rope groove undergoes a surface hardening process (typically induction or flame hardening) to achieve a hardness of HRC 45-55. This hardened layer dramatically resists the abrasive action of the wire rope, ensuring the groove profile is maintained for a much longer period.
Rigorous Quality Control: Every sheave is subject to strict quality inspections, including dimensional checks and Non-Destructive Testing (NDT) like Magnetic Particle Inspection (MPI) or Ultrasonic Testing (UT) to guarantee it is free from any defects.
We manufacture OEM and replacement sheaves for a wide range of machinery:
Mobile Cranes (Boom tip and hook block sheaves)
Overhead and Gantry Cranes (Hoist trolley sheaves)
Port and Container Cranes
Derrick Cranes
Industrial Hoists and Winches
