What It Is / How It Works

This is a mechanical screw jack, a hand-operated lifting tool that uses a worm gear and screw mechanism to raise heavy loads. It is built with an all-steel integral casting for strength and stability, and it features a self-locking worm gear that holds the load in place when you stop cranking.

Who It's For / Use Cases

It is useful for raising cars, trucks, tractors, and agricultural implements for maintenance, repair, or support. The manual operation makes it a dependable choice for jobs where power tools are not available or preferred.

How to Use / Care

1. Place the jack on a firm, level surface and position the saddle under the load's lifting point.
2. Insert the ratchet handle into the drive socket and crank it to raise the load gradually.
3. Once the load is at the desired height, stop cranking; the self-locking worm gear holds it in place.
4. To lower, reverse the crank direction slowly and carefully.

How to Choose

Choose a screw jack based on the weight you need to lift and the type of work you do.
