About Key Plant welding rotators

CR Series


Our heavy duty, built to last conventional rotators and turning rolls are designed and manufactured to tolerate the hardest, hard-wearing and unrelenting workload environments. The powered drive units are controlled by a five-function pendant with a variable speed potentiometer, giving the operator full control of the rotating workpiece.

SAR Series

Self aligning

Engineered to make automated adjustments to accommodate the rotation of workpieces with various weights and diameters. Our self aligning rotators and turning rolls further enhance; operator safety, productivity, weld quality and reduce worker fatigue. Self aligning welding rotators are the preferred option when working with thin-wall workpieces.

ADR Series

Anti-drift systems

Anti-drift rotator systems correct and minimise workpiece drift, whilst maintaining a constant centre line height position. Originally developed for the nuclear industry, Key Plant anti-drift systems are designed to suit a range of applications and processes, such as; narrow gap welding, continuous overlay welding and long periods of vessel pre-heating.

PR Series

Pipe rollers

The ideal solution for handling; low weight and small diameter workpieces in fabrication workshops. Key Plant design and manufacture a selection of different small pipe roller models; with speed adjustable controls and foot pedal options. Their lightweight and portable design, means they can be easily carried and set up at pipe shops and work sites.

Special purpose
