Sometimes welding rotators are also called turning rolls or tank rotators.


They have two typical types - conventional and self aligning and rotators.


Self aligning rotators have three advantages over conventional rotators:
1.The self aligning rotator of the wheel brackets allows the wheels to automatically align themselves when
a pipe or vessel is loaded onto the sections, irrespective of ovality, to accommodate any diameter within
their range.


But conventional welding rotators have to be adjusted manually across the frames to accommodate the varying diameters within their range.


2.The top rollers of the self aligning welding rotators incorporate either clutches to allow the top roller
to free wheel or can be free wheeling to allow a vessel to be loaded onto the sections without any fear of
damage to the transmission drive through negligent loading of a vessel.


However,conventional rollers do not incorporate clutches so damage may occur to the transmission drive if
a vessel is loaded negligently on the rollers.


3.With self aligning welding rotators, the vessel or pipe is supported on 4 wheels which help to maintain
positive rotation especially when accounting for weld beads on the vessel and are less likely to indent the
vessel when supporting thinner wall vessels.
