Ten-Four Stairs
Gary, Ind.-based Ten-Four Stairs’ unique product of the same name is intended to reduce the hassle of climbing on and off semi-trailers, as well as closing the 60-inch gap between trailer rear and road to prevent cars from sliding under the trailer during rear-end accidents.

The system is constructed with a non-slip, non-skid surface to ensure footing when climbing up or down the unit, and is built with a closed-in, step back to prevent a driver slipping through the step. The system is centrally located and welded at the trailing end of the trailer, between the longitudinally extending I beams. Side bearing handles carry a 400-pound weight bearing capacity.

Also, a one and a half-inch hydraulic-assisted, hinged cover plate eliminates the lost floor space, allowing the driver to load as usual, and is capable of handling normal rear loading and unloading of a forklift.

The system is available as an option for installation on most new trailers or they can be custom retrofitted to an existing one, the company says. Each stair system is fabricated from either aluminum or steel, depending on the trailer, and the company says it can also install aluminum stairs in steel-framed trailers.
