Hygienic Screw Hoist

BLM/250/2448/B Hygienic Screw Hoist

This Hygienic Screw Hoist was designed to lift a liquid tank to a maximum height of 2448mm above the floor and had a Safe Working Load of 250 Kgs. There was also an intermediate position where the tank stopped to enable the Operator to attach a discharge hose during the travel up and disconnect the hose during the travel down. The Hygienic Screw Hoist is manufactured from Grade 304 stainless steel, is a welded construction throughout and is designed to be bolted to the floor. The lifting is achieved by a 32mm x 20mm pitch ball screw driven by a motor gearbox mounted at the top of the main column. The Hygienic Screw Hoist incorporated a load arrestor mechanism, which prevented a load from falling to the floor in the extremely unlikely event of the ball screw failing.
