Options and Features

Gripper Chuck

Add a X3 3 jaw welding gripper chuck to your Headstock for internal and external clamping. We also can design custom jigs and toolings to suit your needs.

Elbow Jigs

We design, manufacture and supply a range of elbow jigs that can handle pipe diameters upto 50″. Ideal for welding elbow joints and alternating direction tasks.

DS14 Diameter Selector

Input the welding diameter of your workpiece. The DS14 automatically calculates the required RPM of the positioner table, and sets the speed demand in the inverter drive (VFD).

Man-O-Matic

The innovative Man-O-Matic controller enables a sequence of pre-determined positions to be set. Contact us for more information.

Precision Control

For workpieces that require the ultimate precision, we can provide rotational speed through a closed loop encoder feedback, for high accuracy speed control.

Integration

Create an automated solution and optimise your productivity by integrating your headstock with other Key Plant equipment, like column and boom manipulators.
