The crane pulley is a critical lifting component engineered by Weihua, designed to guide wire ropes during lifting and lowering operations. Weihua crane pulleys are widely used in various crane systems, offering enhanced safety, stability, and durability in demanding lifting environments.

Crane Pulley Key Features and Benefits

• 1. High-Strength Materials: Manufactured using forged alloy steel, ductile cast iron, or cast steel, depending on the application. All materials meet ISO and FEM standards for tensile strength and fatigue resistance.

• 2. Precision Groove Design: Rope grooves are CNC-machined to exact dimensions to prevent rope slippage, minimize wear, and maintain cable alignment under dynamic loads.

• 3. Bearing System: Equipped with sealed roller or ball bearings to ensure smooth, low-resistance rotation even under full-load conditions. Bearings are maintenance-friendly and long-lasting.

• 4. Corrosion Protection: Surface treatments include shot blasting, rust-proof painting, powder coating, or galvanization for marine and outdoor use. Optional stainless steel construction is available for highly corrosive environments.

• 5. Load Range and Configurations: Available for lifting capacities ranging from 1 ton to over 300 ton, with customizable sheave diameters and pulley combinations (1–6 sheaves or more).

• 6. Compatibility: Compatible with electric wire rope hoists, electric winches, lifting beams, and all types of cranes including double girder, single girder, portal, and shipyard cranes.
