Leveling Jacks

Mount these jacks to equipment to raise and level it.

Leveling Jacks with Wheel

A swivel caster lets you reposition your load.

Scissor Jacks

Fit these compact jacks under low-height loads.

Wrench-Adjustable Screw Jacks

Wrench-adjustable jacks require less clearance to turn than bar-adjustable jacks.

Bar-Adjustable Screw Jacks

The turning bar gives you leverage to lift heavier loads than wrench-adjustable screw jacks.

Ratchet Jacks

These jacks can be used to lift, spread, push, pull, and clamp.

Two-Height Ratchet Jacks

Choose between two lifting points—use the toe for lifting loads low to the ground, or use the saddle when you need a higher, more stable lifting point.

Screw Jack Stands

The screw adjustment allows you to make small changes to the height of your load.

Ratchet Jack Stands

The ratcheting action makes adjusting these jacks under load easier than screw jack stands.

Screw Jacks

Acme Screw Jacks

Broad, strong Acme threads make these screw jacks better than ball screw jacks for heavy loads, intermittent positioning applications, and where vibration is present.

Acme Screw Jacks with Mounting Plate

The mounting plate provides a flat surface for supporting loads.

Mounting Plates for Acme Screw Jacks

Add a flat mounting surface to to a screw jack to support loads.

Eyelet End Fittings for Acme Screw Jacks

Attach these fittings to the end of a screw jack to create pivoting connections with clevis rod ends and other linkages.

Mounting Plates for Ball Screw Jacks

Add a flat mounting surface to a ball screw jack to support loads.

Ball Screw Jacks

Low-friction ball bearings allow these screw jacks to use half the power required by an Acme screw jack to lift the same load. Typically used as actuators, they run at higher speeds than Acme screw jacks.

Eyelet End Fittings for Ball Screw Jacks

Attach these fittings to the end of a ball screw jack to create pivoting connections with clevis rod ends and other linkages.
