  • Patent number: 5971692
    Abstract: A loading dock having a truck leveler for allowing the truck to be positioned at different heights. The loading dock includes a dock surface, a driveway extending from the dock surface and positioned at a level below the dock surface, and a ramp movably interconnected with the driveway. The driveway defines a tire path along which a truck tire will travel when a truck is backed toward the dock surface. The ramp is movable from an active position aligned with the tire path to an inactive position out of the tire path. The ramp can be pivotally interconnected with the driveway. Alternatively, the ramp can be linearly slidably interconnected with the driveway. In either embodiment, a power actuator (e.g., a hydraulic cylinder) can be operatively connected with the ramp and positioned to pivot the ramp between the active and inactive positions.
