traveling nut screw jack
A screw jack is a gearbox assembly (either worm gear or bevel gear) and a transmission product (lead screw, ball screw or roller screw) which through use of a motor is used to convert rotary into linear motion. They can be used to push, pull, tension, lock, unlock, tilt, pivot, roll, slide and lift or lower loads, anything from a few kilos to thousands of tonnes.
A screw jack system includes essential components such as heavy-duty vertical screw or power screw (leadscrew) with a load table mounted on its top, a worm or bevel gearbox assembly, and a motor to provide rotary motion. The screw jack is operated by turning the vertical screw or power screw with the help of gear system and motor, to convert rotary motion into linear motion.
