dock leveler
A permanently installed movable ramp that facilitates freight transport between levels in a loading area.
A dock leveler is a movable ramp or floor extension that is permanently installed in a loading dock or similar area to facilitate transport or shifting of cargo between different levels.
The ramp or floor extension can move while remaining a permanent part of the loading area. Its movement accommodates a difference in level along the cargo-transfer route.
A fixed slope has no movable leveling element, while a loose ramp lacks the permanent installation described here. The dock leveler combines an installed loading-area fixture with movement to bridge differing cargo-handling levels.
