If the overhead door is closed and locked, a mechanical dock leveler will not damage the door when the dock leveler is activated. An air powered dock leveler or hydraulic dock leveler will cause extensive damage to the closed and locked overhead door if operated. To address this concern for potential damage, both air powered and hydraulic dock levelers can be ordered with an optional overhead door interlock switch. A striker plate on the door activates a wall installed limit switch when the door is opened. Only when the limit switch is activated, will the dock leveler operate. Contact a Pentalift Sales Representative for further information.
