Learn about our Screw Stem Hoists

Screw Stem Hoist are commonly used on vertical Slide Gates, Jet Flow Gates and Fixed Cone Valves. Typically, one or two (dual) stems are connected to the gate and extended in the direction of travel. The stems are threaded and driven through a bronze drive nut that is rotated by hand or power driven with electrical actuators. Electrical actuators are compact and include onboard controls with limit switches and position indication. Screw Stem Hoists are self-locking, meaning position is held without operator forces, and are often referred to as Self Locking Screw Stem Hoists. Screw stems require routine greasing maintenance.
