Sometimes, we also use screw jacks to lift some valuable mechanical equipment parts, precision mechanical equipment, or some heavy objects whose appearance is easy to be damaged. Our intention is to complete the lifting operation, and we do not want to cause any wear and injury to the heavy objects due to the lifting of the jacks. At this time, we can pad soft materials such as thin wood and aluminum plates between the head and the objects to be lifted.

When using the jack, the safety cushion block shall also be set beside it, and the height of the safety cushion block shall be adjusted in time with the lifting of the workpiece. When several screw jacks are used simultaneously, soft materials with the same height shall be selected.
