The screw jacks can be employed singularly or in groups properly connected with shafts, joints, and/or bevel gearboxes. They can be driven by different motors: electrical, with either alternating or direct current, as well as hydraulic or pneumatic motors. Also they can be driven manually or with any other type of transmission.

Screw jacks come in many forms. The basic principle of converting rotary motion into vertical or horizontal movement is always present, yet they can be as simple as a hand wheel driven single unit up to linked multiple motorized units lifting many tonnes whilst keeping the load stable and level.

They can be driven by different motors: electrical, with either alternating or direct current, as well as hydraulic or pneumatic motors. Also they can be driven manually or with any other kinds of transmission. Our ball screw jacks are designed and manufactured using innovative technology so to supply a product which identifies itself with the sta

Electro-mechanical SCREW JACK device for uplifting and positioning One of the most familiar kinds of jackscrews are the traditional manually powered, hand-turned types, which operate by applying force against a handle which makes the screw rise from a base unit, lifting or lowering a load. Other common means of driving jackscrews are either ac or

Each unit is composed by an electric motor, a gear speed reducer, the screw (or worm shaft) and a worm gear all contained in a solid and stable steel frame. The screw jacks enable to move heavy loads slowly, accurately and safely. The advantage of such system is the simplicity.

The longer the stroke, the less load it can lift, considering the compression limit of the screw jack. It can powered by motor, belt or handwheel. Can be mounted uprightly, horizontally or invertedly for different applications with different screw end. It is stable, accurate and space saving.

Ball Screw Jacks with 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.
