Welding Rotators are very essential equipments for heavy and light fabrication shop.
Cu-Built Hydraulic Shell to Shell Fit-Up Rotators are specially designed to Align, Rotate and Support two sections of same diameter Shells for 'Tack Welding' or 'Full Circumferential Seam Welding'. Different diameters of cylindrical jobs can be accommodated on them as per the design for which it is indented. Fit Up Rotators are Used for assembly or Fit-Up of Long Pipe / Tanks / Wind Tower / Vessel, etc.

Fit Up Rotators have Four Units, Two Units (1No. Drive Unit + 1No. Idler Unit) are with Trolley Wheels and the other Two are Hydraulic Fit Up Units Fixed Base Type. Trolley of Drive Unit has inbuilt drive system, so that the shell section supported on them can be moved forward or backward, in order to butt the shell edge, against the edge of theother shell on the fixed units.

If different length of shells are involved, it is better to have these of the units on Trolley wheels, and only one unit fixed. This will help to easily adjust the distance between the shell supporting units to the length of the shell sections.
