What is Auto Return on a Hydraulic Dock Leveler?

In the majority of applications the dock attendant positions the dock leveler on the truck. When the truck is loaded the dock attendant typically operates and returns the dock leveler to the stored closed position. If there is no dock attendant and the truck departs with the dock leveler in position the dock leveler lowers and the lip slowly retracts. If equipped with an optional auto return when the lip reaches the fully retracted position a limit switch is activated. This starts the lift motor. The deck raises and the lip clears the lip keepers. The timer shuts off the motor and the deck lowers to the properly stored closed position.

What are the safety precautions that should be taken when doing maintenance on a lift table?

When performing maintenance on a lift table all maintenance must be done by trained personnel and all electrical work is suggested to be performed by an electrician. Nobody should go under the lift table unless properly supported by the lift table’s maintenance stand. Performing maintenance on a lift table should never be done with any sort of load on platform because the maintenance stand of the lift table is only designed to withstand the table’s weight without a load on platform. To increase safety and ease of maintenance, a central lubrication option can be acquired at time of purchase to lubricate leg rollers, leg pivot points, and cylinder points at a point of easy access.

What is a self leveling lift table?

A self leveling lift table is a table that adjusts its height automatically when weight is added or removed to the unit. Its main use is to help improve ergonomics in the work place by keeping the load at a comfortable height for the operator. Self leveling lift tables are also equipped with a rotating top to minimize reaching and provide access to any product on the table more conveniently. Options available include a rotator break, fork pockets, and accordion bellows. Self leveling lift tables are spring actuated which would be rated as a green product because there is no requirement for an incoming power supply or risk of contamination from a hydraulic oil spill.
