Basically a dock leveler is an adjustable ramp that is designed to provide a transition plate from the building floor to the truck bed to be used during loading or unloading trucks. When a lift truck drives from the building floor across the dock leveler onto the bed of the delivery truck the trucks suspension lowers under the weight of the lift truck forcing the dock leveler platform and the extended lip assembly downward. When the lift truck drives back off the truck across the dock leveler into the building the weight is removed from the trucks suspension and this forces the dock leveler platform and the extended lip assembly back up. This normal up and down truck bed movement during loading or unloading and the corresponding dock leveler platform and extended lip assembly movement up and down is referred to as dock leveler float.
