Screw Jacks in construction

Often found in climbing mechanism of construction,the screw jacks use physical means to raise and lower loads, which typically range from 5 tons to 30 tons. A screw jack is a common type of mechanical jack, which works via a motor and gearbox by an operator. A screw uses the shape of its threads to raise or lower the load, or a traveling nut does the lifting while the screw turns in place. Mechanical jacks are self-locking(not for ball screw), which means that when power is removed from the jack, the screw stays in place until power resumes. This setup makes mechanical jacks safer than their hydraulic counterparts, because users don't have to fear a loss of power. The main components of screw jacks are; trapezoidal lifting screw also known as lead screw, worm screw, worm gear and gear housing. A worm screw is rotated manually or by a motor. With the rotation of the worm gear, the lead screw in it moves upwards or downwards linearly. The feed rate of the screw depends on the turning speed, the number of teeth of the gears and the size of the screw pitch. In some models of jackscrews, The lifting screw does not move up and down. It only rotates around its axis. A lifting nut (also known as a travelling nut) moves along the lead screw. The lifting nut of the screw jack is made of bronze to decrease friction.
