SPRINGS

Open & Closed Trailers

Springs play a critical role in lift-assist systems for enclosed cargo trailers, box trailers, and service trailers. Torsion spring assemblies are commonly used to support roll-up and swing-up trailer doors, helping operators raise and lower doors smoothly while reducing strain and improving safety. These systems are found on delivery trailers, contractor trailers, mobile workshops, and fleet service units where dependable door operation is essential for daily use.

Ramp Assist Springs

Ramp assist systems are essential for trailers designed to load and unload equipment, vehicles, and heavy materials. Torsion and double torsion springs are used in trailer ramps and dovetails to help offset the weight of long, steel loading surfaces. These systems are commonly found on equipment trailers, car haulers, landscaping trailers, and utility trailers where frequent loading is required.

In addition, large wire diameter extension springs are often used in specialized ramp assist applications that demand higher load capacity and long cycle life. This niche capability supports trailer manufacturers producing heavy-duty and custom configurations.

Spring Assist Kits

Spring assist kits provide a complete lifting solution for trailer doors and ramps. These assemblies typically include springs, shafts, drums, and cables designed to work together as a single system. They are commonly used in enclosed trailers, commercial transport trailers, and specialty trailers where consistent lift performance and easier operation are key selling points. Complete kits help manufacturers streamline installation while delivering a dependable end product for the customer.
