Extensive Range of Rotators and Turning Rolls

Key Plant Automation offers a diverse range of robust and reliable equipment available for purchase, hire, or lease. Our catalog includes:

Conventional Rotators (CR Series)

These heavy-duty, built-to-last conventional welding rotators and turning rolls are designed to tolerate the most challenging and hard-wearing 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.

Self-Aligning Rotators (SAR Series)

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

Anti-Drift Systems (ADR Series)

These systems correct and minimise workpiece drift while maintaining a constant centerline height position. Originally developed for the nuclear industry, Key Plant anti-drift systems are designed to suit a range of applications and processes, including narrow gap welding, continuous overlay welding, and long periods of vessel pre-heating.

Pipe Rollers (PR Series)

The ideal solution for handling low-weight and small-diameter workpieces in fabrication workshops. Key Plant designs and manufactures a selection of different small pipe roller models with speed-adjustable controls and foot pedal options. Their lightweight and portable design makes them easy to carry and set up at pipe shops and work sites.
