Abstract
A dock leveler for use in a loading dock. The dock leveler includes a ramp, an inflatable assembly, and a gas moving device. The ramp includes an undersurface and is pivotal between a generally horizontal lowered position and an upwardly-inclined, raised position. The inflatable assembly is positioned under the ramp. The gas-moving device is mounted adjacent to the undersurface and fluidly connected to the inflatable assembly. A conduit fluidly connects the top of the inflatable assembly and the gas-moving device to provide gas to the top of the inflatable assembly. A support is positioned under and supports the inflatable assembly. The support is supported by a pit floor and is unsecured to the pit floor. The support can be manually lifted completely out of engagement with the pit floor when the ramp is in the raised position.
