Mechanical Dock Levelers use a series of springs and levers to raise the platform and extend the lip assembly. The Mechanical Dock Leveler is then “walked down” into position on the delivery truck bed.

Air Powered Dock Levelers, though structurally the same, use a push button control station to operate a 115/1/60 blower, which inflates an air bladder to raise the platform. A mechanical assembly operates the hinged lip. Once the lip is actuated and fully extended, the dock attendant releases the control button and the dock leveler automatically lowers into position on the truck bed.

Mechanical Dock Levelers are more cost effective at the time of purchase.

Air Powered Dock Levelers cost more to purchase but because they have fewer mechanical components, require less maintenance and are more ergonomically accepted.
