In hazardous areas or food grade applications where hydraulics can’t be utilized is an ideal solution for a mechanical lift table. The mechanical series of lift tables can be equipped with manual operation for when there are stringent electrical requirements. It can also be battery or electrically powered as well. Lifting operation is offered with a choice between two different mechanical systems. One is an acme screw-type lift and the other is a cable winch-type lift with a worm gear drive that keeps the load at any position desired without drifting. The manual crank handle is conveniently located at working height. The unit can also be outfitted with wheels for portability purposes. The mechanical lift is also available with a butcher block top for applications where a softer platform is needed for when you are handling delicate parts and or materials.
