Abstract
An auxiliary energy source is connected to the manually operated lift head of a vacuum lift system for connection of an accessory. Thus, electrical or compressed air energy is made conveniently available to power a load rotating accessory, a clamp, or the like, preferably by means of feeding a conduit line coaxially within the flexible tubing of the lift system. This is particularly useful to prevent interference or disarray of an auxiliary line that must be manipulated in tandem with the lift head, and is operable with rotary type lift systems that permit 360 degree rotation of the lift head.
