Trailer-Unloading Rolling Platform Ladders




The platform height of these ladders is designed to line up with most trailers. An open pass-through lets you step right off onto the trailer. The 50° incline is more gradual than that of typical ladders, so it’s easier to climb and descend. Serrated steps and platform prevent slipping and allow liquids and debris to pass through. All ladders have at least one chain at the top of the platform to prevent falls when they aren’t pushed against a surface. Swap in safety gates (sold separately) for a more secure railing.
The number of steps listed includes the platform. Three- and four-step ladders are good for drop-deck trailers. Five-step ladders are the right height for semitruck trailers and loading docks. Six-step ladders work with flatbed trailers.
Ladders with two rigid casters tilt to roll—they stay in place when they’re upright. Ladders with two swivel and two rigid casters can be rolled without tilting. A step lock keeps the casters locked until you tap a foot pedal.
Assembled ladders have fully welded connections. Unassembled ladders ship flat.
Note: All ladders meet OSHA or Cal/OSHA dimensional and construction standards. Check local, state, and federal codes, including OSHA, for safe set up and operating practices.

Truck-Mount Ladders
Safely climb on and off flatbed trailers. Choose a ladder tall enough to reach your flatbed—standard platforms are about 50" from the ground; drop decks are about 36". Quick to install and remove, these ladders hook onto the rub rail of most flatbeds. They’re made of aluminum, so they’re lightweight and corrosion resistant.
Style 1 must be in contact with the ground during use. These ladders have ribbed steps for good slip resistance. Keep them installed while driving—just swing them upright and secure them with the included brackets.
Styles 2 and 3 don’t need to touch the ground to support your climbing. This is useful when working on uneven surfaces. They should be removed and stored before driving. The steps are either perforated or serrated—they have openings so liquids can drain and debris can fall through. All steps provide good traction, but serrated steps are more slip resistant than perforated steps. Style 3 store in small spaces because the legs fold up and the grab posts fold down.
Ladders that cannot be sold to the listed areas are restricted due to product regulations.
Note: Ladders that have OSHA or Cal/OSHA specifications listed meet dimensional and construction standards. Check local, state, and federal codes, including OSHA, for safe set up and operating practices.
