JWM Series Trapezoid Screw Jacks for Lifting Equipment

A screw jack is a mechanical device that uses a screw to lift or move a heavy object. It is a simple and versatile tool used in a variety of applications, including automotive, construction, and manufacturing.

A jack is made up of screws, nuts, and handles. The screw is threaded and connected to a fixed base. The nut is fixed to the load that needs to be lifted. The handle is used to turn the screw in order to lift the nut and load.

The amount of force required to turn a screw is determined by the pitch of the screw. Pitch is the distance between the screw threads. A coarse-pitch screw requires more force to turn than a fine-pitch screw.

The weight a screw jack can lift is determined by the bearing capacity of the screw. Carrying capacity refers to the maximum weight that the screw can be safely lifted.
