Standard turning rolls support and rotate vessels ranging from 100 lbs. (45 kg) to 400,000 lbs. (181,437 kg) and workpiece diameters ranging from 6 in (15 cm) to 30 ft (9 m). Our model TDRA-30 turning roll, when combined with (2) TIRA-30 idlers, can support workpieces of up to 90,000 lbs. and ranging in diameter from 8″ to 240″.
Constant centerline turning rolls allow operators to adjust wheel spacing to accommodate workpieces with various diameters while maintaining the relative position of the welding tip. This configuration is ideal for in-line manufacturing processes and automated welding cells where both variability and repeatability are critical.
Power elevating turning rolls accommodate the up and down movement of rolls. This configuration drastically improves setup times where high workpiece variability exists. They also work for non-cylindrical workpieces where multiple rolls are needed at varying centerline heights. Note that custom bases may be required to elevate and support workpieces.
