Screw Jack Systems
Custom-Designed For Precise Needs

As well as supplying screw jacks, bevel gearboxes and linear actuators, we also specialise in modular system design.

Our modular systems are particularly effective for conveyor belt adjustment in canning, food production and packaging lines — where precise, repeatable height and angle control is critical for maintaining throughput, reducing changeover times and protecting product quality.

If you require a specific layout and cannot find it on our website, ask our team of design engineers and they will happily supply you with a fully functioning model.

What Makes Our Systems ‘Modular’?

Every component in the Kelston range — screw jacks, drive shafts and bevel gearboxes — is designed to work independently or as part of a synchronised system. Think of it like building blocks: you can link any number of screw jacks together through a single drive input to raise, lower or tilt conveyor sections in perfect unison.

This means you can:

- Adjust conveyor belt height at multiple points simultaneously, keeping the belt perfectly level across its full width.

- Tilt sections to control product flow between stages — for example, angling a transfer conveyor between a filler and a capper.

- Expand or reconfigure the system if your line layout changes, without replacing the entire mechanism.

- Drive the full system from a single motor input, reducing complexity and maintenance overhead.
