Abstract
A dock leveler for use in a loading dock. The dock leveler includes a ramp, an inflatable assembly, and a support structure. The ramp pivots between a generally horizontal lowered position and an upwardly-inclined raised position. The inflatable assembly is positioned under the ramp and adapted to generate a force. The support structure is positioned between the inflatable assembly and the ramp and adapted to transfer the force of the inflatable assembly to the bottom of the ramp to move the ramp from the lowered position to the raised position. A conduit fluidly connects to the inflatable assembly through the support structure.
