What is the Lifting Torque Required for a Screw Jack ?
The input torque for a single screw jack depends on the load, the worm gear ratio, type of screw (machine screw or ball screw) and the pitch of the lifting screw. Torque values are listed in the individual product specification charts based on capacity loads. For loads from 25% to 100% of screw jack model capacity, torque requirements are approximately proportional to the load.
