Jacks

Worm gear jacks from UNIMEK SpA are easy to use, reliable and require a minimum of maintenance. This makes them a very useful machine element in many different contexts.

 

They can be used to:
• lift
• drag
• balance
• position

 

Even with very high demands on personal safety, the jack is a useful alternative because the worm screw in our jacks is 100% self-locking. They can be used without external braking or locking devices. The lifting force of our jacks is a maximum of 1000 kN.

Aleph jacks with housing in composite

This series of jacks has a housing and worm wheel made of a composite material.

 

This means, among other things, that it can work without lubrication – an advantage in many built-in cases. Currently, aleph is available in three sizes, all with trapezoidal screws.
