Abstract
An example dock leveler with safety supports including a deck having a deck plate, a plurality of support beams, a first side plate and a second side plate. The deck plate has an outer perimeter defined by a front edge, a rear edge, a first lateral edge and a second lateral edge. A first deck obstruction extends underneath the deck plate and is selectively configurable to at least one of a blocking position or a stored position. The first deck obstruction is elongate in a lateral direction and the first deck obstruction has a protruding end. The first side plate is closer to the protruding end when the first deck obstruction is in the stored position than when the first deck obstruction is in the blocking position. The first deck obstruction extends laterally beyond the deck width when the deck obstruction is in the blocking position. The first deck obstruction includes a pulling enhancement at the protruding end.
