Industrial Grade Dock Leveler provides a bridge to the trailer as well as a ramp to facilitate the transition in height from dock to trailer. The Dock Leveler comes in mechanical and hydraulic models. The Dock Leveler in mechanical models requires the operator to pull a chain and then walk down on the leveller to engage it, while hydraulic models provide automatic functionality from push buttons usually mounted on the wall next to the dock door. Industrial Grade Dock Leveler is equipped with signalling devices such as signal lights.
