Crane Sheaves by GloryCrane – Key Features
A crane sheave is a grooved wheel used in cranes to guide and support wire ropes. It plays a critical role in the lifting process by redirecting the wire rope, reducing friction, and distributing the load evenly to ensure smooth and efficient lifting operations. In crane systems, the sheave is integral to the hoisting mechanism, while the pulley group includes multiple components such as the sheave, axle, and housing. Generally, the hook set of the crane works with a movable pulley system to save labor.
- Load Capacity: 1~160 ton.
- Wire rope Diameter: φ7-82mm, φ 6~11mm for Nylon pulley.
- Sheave Diameter: φ225-1250mm, maximum customizable diameter is 1600mm.
- Hardened Groove: on request with hardened rope groove, quenching depth no less than 20mm.
- Various Material: gray cast iron HT200 or nodular casted iron; ZG20/ZG25/ZG35/ZG45 for casted steel; Q235B/Q345B/C45 for rolled steel plate; 16Mn/20#/C45(1045/45#)/C60/42CrMo4 for forged steel; MC Nylon for Polyamides.
- Advanced Bearing: Can come with advanced bearing systems, such as cylinder roller bearings, deep groove ball bearings and sliding bearings for reduce friction and extend the life of the pulley system. Imported bearings SKF, NSK, FAG or Chinese famous brands LYC, HRB, ZWZ or according to your request.
- Quality Control: Strictly comply with industry standards, such as GB, ISO, DIN, ASTM, etc. Ensure comprehensive testing, such as Ultrasonic Testing (UT), Magnetic Particle Testing (MT), Radiographic Testing (RT), and Chemical Composition Testing.

Groove Diameter
Groove depth and groove angle are critical for sheaves. They ensure that the wire rope does not rub against the flange of the sheave as it enters, runs, or exits the pulley. The groove diameter of the pulley should always be slightly larger than the actual diameter of the wire rope. But if the groove diameter is too large, the rope will get squashed, and if it’s too small, the rope will get pinched. The bending radius also affects the strength of the wire rope. Repeated bending creates stress and fatigue that affects service life and eventually damages the wire rope.
Cast Sheaves
Casting Sheaves are made into blanks through casting process using casted iron or casted steel. And then they are machined into finished pulleys. It has the advantages of low production cost and high efficiency. For some larger size, non-standard shape, complex pulley products, casting is an ideal production method.
Forged Sheaves
Forged sheaves are generally made by free forging. After forging, they are integrally processed, and then undergo subsequent processing steps such as heat treatment. It has good performance and high quality, but the production cost is high. It is generally used in port machinery, offshore operating ships, oil drilling platforms and other places that are not conducive to maintenance and repair.
Nylon Sheaves
The nylon sheave is cast from MC nylon and machined into finished product. Nylon sheaves have the characteristics of light weight, low noise, good mechanical properties, high strength, good toughness, impact resistance and fatigue resistance. Mainly used in large lifting machinery and equipment such as engineering truck cranes, crawler cranes, tower cranes, bridge erecting machines, coal unloading, port machinery, elevators, etc.
