Abstract
A highway towable dock-lift trailer for use in loading and/or unloading trucks, rail cars, containers, etc., for example, in any location and across all industries and applications, and can include a tow bar that allows the trailer be towed to a desirable position or location. When the tow bar is removed from the trailer or repositioned relative to the frame, either a truck can back into position or the trailer lift can be positioned against the truck, etc., and the trailer lift is then ready to load and/or offload the truck. As an operator elevates the loading platform of the trailer, via hydraulic lifting means, for example, the lift can move up to truck height and hydraulically operated lifting arms can operate opposed automatic folding ramps, which simultaneously can open for load distribution and close for safety. The trailer can include a plurality of screw down or hydraulically actuated jacks to level and secure the platform, and the trailer can include bumpers to absorb the forces from a truck accidentally impacting the trailer.
