J Range Screw Jacks
5kN - 1000kN Lifting Capacity

Our J Range Screw Jacks are perfect for heavier industrial applications as they can be designed to almost any specification.

Lifting loads of up to 1000kN (and beyond) can be accommodated, along with customisable travel speeds and torque requirements to meet your objectives. We can even help you devise custom solutions that enable them to run as a single synchronised system.

These classic Screw Jacks typically feature a precision worm gear set with a powerful, steel lead screw. They can be configured for either a translating or rotating linear motion, with either an upright or inverted lifting orientation.

We can build the housing from any metal that will do the job – whether that is durable cast iron or non-corrosive materials like stainless steel – and utilise either machine screws or ball screws for more dynamic lifting requirements.
