Polyurethane buffers are widely used in overhead cranes, gantry cranes, 提昇機, and other industrial lifting systems to enhance operational safety and extend the service life of the equipment.

Polyurethane Crane Buffer Features

• 1. High Energy Absorption – Effectively absorbs impact forces during crane travel and stopping.

• 2. Durable Material – Made of premium polyurethane with excellent wear resistance and mechanical strength.

• 3. Weather & Oil Resistance – Performs reliably under extreme temperatures, exposure to oil, and outdoor environments.

• 4. Noise Reduction – Minimizes vibration and operational noise.

• 5. Compact Design – Easy installation and replacement with minimal maintenance.

• 6. Long Service Life – Much longer lifespan compared to traditional rubber buffers.

技術規格 (典型範圍)

材料	High-strength polyurethane elastomer
Hardness	70–95 Shore A
工作溫度	-40°C to +80°C
Compression Set	Low, ensuring long-term resilience
Energy Absorption Capacity	Up to 50–80% of impact energy (varies by size)
Color	Customizable (commonly yellow, red, or blue)

Applications

• 1. Overhead cranes – To reduce impact when the trolley or bridge reaches end stops.

• 2. Gantry cranes – Installed on travel mechanisms for smooth and safe operation.

• 3. Electric Hoists – Protect lifting systems from overload impact.

• 4. Industrial machinery – Acts as a shock absorber in heavy-duty equipment.

Advantages of Using Polyurethane Buffers in Cranes

• 1. Improved Safety: Prevents sudden shocks that may damage crane structures or cargo.

• 2. Cost Efficiency: Reduces maintenance costs and downtime by protecting components.

• 3. 多功能性: Suitable for various crane models and industrial environments.

• 4. Environmentally Friendly: Polyurethane is recyclable and has low environmental impact compared to traditional rubber.
