Product Description
In cranes, hoists, and heavy-duty lifting systems, the sheave is a critical component subjected to immense loads and constant wear. A failed sheave not only causes expensive downtime but also poses a significant safety risk.
Yile Machinery manufactures high-performance, custom-engineered steel sheaves designed for maximum reliability and service life in the world's most demanding applications, including cranes, mining, and marine equipment.
Our commitment to quality begins with the selection of premium materials and extends through every stage of manufacturing.
Advanced Material Options: We manufacture sheaves from high-grade materials selected for your specific load and environmental requirements:
Forged Steel (e.g., C45, 42CrMo): Offers the highest strength, impact resistance, and fatigue life, ideal for mission-critical applications.
Cast Steel (e.g., ZG35SiMn): Provides excellent wear characteristics and allows for complex geometries, suitable for a wide range of heavy-duty uses.
Specialized Heat Treatment: The service life of a sheave and the wire rope running on it is determined by the hardness of the groove. We employ advanced heat treatment processes:
Groove Hardening (Induction or Flame): Creates a hardened wear surface (typically ≥ HRC45) that drastically resists wear and corrugation.
Quenching & Tempering (Q&T): A full-body heat treatment that refines the steel's grain structure, improving its overall toughness and tensile strength.
Precision CNC Machining: Every sheave is precision machined to ensure a perfectly profiled rope groove and smooth surface finish. This is critical for minimizing friction and maximizing the operational life of expensive wire rope.
Integrated Bearing Solutions: Sheaves can be supplied ready for installation with high-quality bearing options, including heavy-duty bronze bushings for low-speed, high-load scenarios or sealed roller bearings for higher-speed applications.
We specialize in producing sheaves to meet your exact OEM or replacement part specifications. Our engineering team can work from technical drawings, an existing sample, or your specific operational parameters.
Customization options include:
Diameter and Width
Wire Rope Size and Groove Profile
Material Selection (Forged or Cast)
Bearing Type and Configuration
Hub Design and Bore Dimensions
Surface Finish and Coatings
Our heavy-duty sheaves are trusted components in a wide variety of equipment:
Cranes: Mobile cranes, overhead (EOT) cranes, tower cranes, and port cranes.
Mining: Mine hoists, draglines, electric rope shovels, and conveyors.
Marine & Offshore: Deck winches, anchor handling systems, and offshore platform cranes.
Construction: Piling rigs, excavators, and other heavy machinery.
