April 22, 2016, 12:06 pm - 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.

TENV stands for Totally Enclosed Not Ventilated Electric Motors. These are used in a wide variety of smaller horsepower applications. This type of electric motor radiates its excess heat through the body of the motor. It is commonly built with special high temperature insulation. TEFC stands for Totally Enclosed, Fan-Cooled Electric Motor. These are constructed with a small fan on the rear shaft covered by housing. The fan is used to assist in cooling the electric motor. Dock levelers commonly use TENV motors and dock lifts commonly use TEFC motors. Contact a Pentalift Sales Representative for further information.

A hydraulic conversion kit consists of a hydraulic lift cylinder, a hydraulic lip cylinder, electric power unit, control station, and all of the brackets required.
