Features of screw jacks
One of the biggest benefits of this type of jack is that they are self-locking and will stay in place. You don’t have to worry about them failing. Even when the rotational force of the screw is gone, it remains motionless, even though the load it is supporting might be extremely heavy. While the screw jacks are basically the same, there are some manufacturing differences, such as the capacity for the jack. Some may have a much higher capacity for lifting and holding weight than the others do. You will notice that many of the newer models have a different type of bottom. Some have a bell shape, which helps to increase their overall stability.
How screw jacks work
You will operate this type of jack by turning the lead screw. Place the screw jack, or several, beneath the equipment or structure that you need to lift, and then turn the lead screw on the jacks. This will raise the platform. Because of the nature of this type of jack, the height of the jack will stay the same without a problem, even with heavy loads. This is why they are so useful when moving large structures.
