クレーン・プーリー

A クレーン・プーリー is a key lifting component. It changes the direction of force and reduces the power needed to hoist heavy loads. By distributing the force across multiple rope falls, this system minimizes wire rope wear. This ensures safer and more efficient overhead crane operations.

Advanced Engineering & Durability

Every industrial crane sheave block we manufacture features high-grade forged steel. The groove surfaces undergo rigorous induction hardening to reach HRC 45–50. This process ensures maximum wear resistance and extends the operational lifespan under heavy industrial loads.

Applications & Reliable Manufacturing

Our lifting pulley assemblies deliver stable performance. They fit overhead traveling cranes, gantry systems, and tower cranes. For complete lifting setups, you can also explore our high-performance クレーンホイール. To learn more about standard hoisting design principles, please refer to the Hoist Manufacturers Institute (HMI) guidelines.

Product Features and Applications

Features:
1. Forged alloy steel construction gives each crane rope pulley high strength, excellent load capacity, and maximum wear resistance.
2. The precision-machined, induction-hardened groove surface effectively resists wire rope friction and dramatically extends rope service life.
3. Versatile single, double, or multiple sheave configurations are custom-tailored to match your specific crane pulley system needs.

Applications:
Our premium crane pulleys are widely used in overhead cranes, gantry cranes, tower cranes, and industrial hoists. Implementing a high-quality wire rope sheave system is vital for heavy-duty lifting in construction, mining, shipyards, and steel mills to lower maintenance costs and improve workplace safety. To learn more about standard hoisting design principles and calculations, you can refer to the official Hoist Manufacturers Institute (HMI) guidelines.

製品詳細

Each Crane Pulley block is meticulously manufactured from high-grade forged alloy steel or ductile iron to guarantee long-term reliability. Through precise CNC machining, the groove dimensions are perfectly tailored to match specific wire rope diameters.

The groove surfaces undergo rigorous heat treatment to achieve a hardness of HRC 45–50, minimizing friction and preventing premature rope damage. Equipped with heavy-duty roller bearings, these wheels ensure smooth rotation and stable performance even under heavy industrial loads. Before shipment, every single component passes strict load testing, non-destructive evaluation, and receives a premium anti-rust coating.
