Polyurethane OHT Overhead Crane Pulley

A Polyurethane OHT (Overhead Traveling) crane pulley is a key component used in overhead crane systems, designed to guide and support the hoisting wire ropes or belts during lifting and transportation operations. Unlike conventional metal pulleys, these pulleys are coated or fully molded with high-performance polyurethane, which provides superior wear resistance, noise reduction, and extended service life.

Key Features

1.High Wear Resistance – Polyurethane material offers excellent resistance to abrasion, ensuring longer durability compared to steel or nylon pulleys.

2.Reduced Noise & Vibration – The polyurethane surface minimizes metal-to-metal contact, reducing operating noise and enhancing workplace safety and comfort.

3.Load-Bearing Capacity – Engineered to withstand the heavy loads typical of OHT crane operations, while maintaining stability and precision.

4.Anti-Slip Performance – The elastic surface of polyurethane improves rope grip, reducing slippage and extending the life of wire ropes.

5.Corrosion Resistance – Unlike steel pulleys, polyurethane-coated pulleys resist rust and chemical attack, making them suitable for harsh industrial environments.

Applications

OHT Cranes in Manufacturing Plants – For handling raw materials, components, and heavy machinery.

Steel Mills and Foundries – Withstanding high loads and extreme operating conditions.

Logistics and Warehouses – Ensuring smooth, quiet, and efficient material movement.

Automotive and Aerospace Industries – Supporting precision lifting where both durability and low noise are required.

Advantages Over Traditional Pulleys

Extended service life of both pulley and wire ropes.

Lower maintenance requirements due to wear resistance.

Reduced downtime and improved operational efficiency.

Lightweight construction compared to all-metal pulleys, reducing overall crane load.

The Polyurethane OHT Overhead Crane Pulley is a durable and efficient component designed to improve crane performance by combining high load-bearing capacity with superior wear resistance. Its polyurethane construction reduces noise, vibration, and rope slippage while offering excellent corrosion protection, making it ideal for heavy-duty applications in manufacturing, logistics, and steel industries. Compared to traditional metal pulleys, it ensures longer service life, lower maintenance, and enhanced operational safety.
