Abstract
The present invention is a vertically stored dock leveler with a telescoping lip that selectively extends and retracts through a range positions relative to the deck. The lip is held and guided by a deck frame carriage. When the deck is raised and lowered, the lip is extended and retracted by an electro-hydraulic control system. When the deck reaches a preselected incline position, the lip is fully extended. Sensors on the underside of the deck determine the incline position of the deck and when the lip is retracted. The leveler is then lowered until the lip engages and rests on the bed of the trailer. Similarly, when the deck is raised for storage and reaches the preselected incline position, the lip is fully retracted prior to returning to its stored position. The telescoping lip is selectively moveable to a range of partially extended position to facilitate end loading a trailer.
