Extendable trailer loader/unloader with user interface section

摘要

An extendable trailer for loading and unloading items from a truck trailer, or other type of transportation unit, includes a user interface section. The user interface section is cantilever supported and both longitudinally and horizontally movable. The user interface section is attached to a mechanically extendable section that includes a conveying surface separate from the conveying surface of the user interface section. The user interface section may be vertically pivotable and may include a locking system which allows longitudinal movement of the user interface section only when the mechanically extendable section is in a fully retracted position. A cable retracting unit is positioned on the mechanically extendable section adjacent the user interface section and takes up slack in the power cable supplying power to the user interface section.
