Polyurethane Buffer

A polyurethane buffer is a vital crane accessory designed to absorb impact energy, reduce shock, and protect structural components during crane operations. Made from high-performance polyurethane elastomers, these buffers ensure long-lasting durability, excellent elasticity, and resistance to wear, making them ideal for heavy-duty lifting equipment.

High Energy Absorption: Effectively absorbs impact forces during crane travel and stopping.
Durable Material: Made of premium polyurethane with excellent wear resistance and mechanical strength.
긴 서비스 수명: Much longer lifespan compared to traditional rubber buffers.
