These aluminum loading ramps are a multi-piece ramp system designed for loading vehicles or other wheeled equipment onto docks, trucks, or trailers. Their aluminum construction makes them lightweight and portable without sacrificing any toughness! These portable aluminum ramps are a great solution for all of your loading and unloading needs. From flatbed trailers to loading docks, these ramps provide heavy-duty support as well as excellent traction due to their textured cross-patterns. This provides extra support and safety for wet and/or muddy tires. The new style ramps have hooks on both ends; The right angle hook is compatible with most trailers on the market and the radius hook allows the user to latch onto the tailgate of the truck bed. A new courser tread provides more traction.
