STATION # 1 SECTION LONG SEAM WELDING Station #1 includes a welding manipulator and rolls for welding both internal and external long seams on tower sections of varying lengths and diameters. The manipulator can be equipped with a MIG station on a powered lifter for the root pass, and a tandem head SAW station for final welding. A selectable powered seam tracker can guide both process down the weld seam. (2) 600 lb. drums mounted on the opposite end of the boom provide wire for the SAW process, and (1) 60 lb. spool mounted near head for MIG Process.

STATION # 2 CIRCUMFERENTIAL INTERNAL FIT-UP Station #2 includes a welding manipulator and fit-up rolls for fitting and welding internal circumferential seams on tower sections of varying lengths and diameters. The manipulator can reach through the end section to first joint to perform the weld. The manipulator can be equipped with a MIG station on a powered lifter for the root pass, and a tandem head SAW station for final welding. A selectable powered seam tracker can guide both process down the weld seam. (2) 600 lb. drums mounted on the opposite end of the boom provide wire for the SAW...

STATION # 3 CIRCUMFERENTIAL EXTERNAL WELD-OUT Station #3 includes a welding manipulator mounted on a travel car and conventional turning rolls for welding external circumferential seams on towers of varying lengths and diameters. The towers will be fitted together and only require final exterior circumferential welds in this station. The manipulator can be equipped with a tandem head SAW station for final welding. A powered seam tracker can guide the torch down the weld seam. (2) 600 lb. drums mounted on the opposite end of the boom provide wire for the SAW process.

Welding Manipulators are available with lift and reach lengths up to 30' and can be customized for specific applications like simple straight line, to circumferential welding. The ram ends can be outfitted with small I.D. single or multiple arc welding heads for long seam and circumferential welding procedures. We have custom designs that can handle extra heavy, and extra long reach applications. All manipulators come standard as pedestal mount, with the option of manual mast rotation, powered rotation, self standing bases, and manual or powered travel cars. Complete welding packages can be...

Self Aligning Turning Rolls Rubber Tires Ideal for tapered work- 50:1 Variable speed drives Thin walled vessels Self-aligning turning rolls adjust wheel centerline setting automatically when the vessel is lowered into place. No couplings to change, no pins to remove or replace. "SA-Rolls" provide constant centerline capabilities making setup and alignment quick and easy. The self aligning rollers, which maintain a constant centerline, can rotate work pieces with diameters as small as 12" and as large as 16' without adjustment or change of drive shafts. SA-Rolls are available in 15 ton to...

Alignment Fit-up Rolls • Machined steel rollers • Wide diameter range • Low voltage hand control Used to fit up and tack shell courses to one another so as to result in a uniform diameter vessel. Available with different length roll sections that couple and uncouple to allow full or partial drive down the line. With proper fit up of the sections to one another, mechanized welding is easily applied for maximum speed and profit. Optional stand-off rings separate the shell tangent from the rollers so wedges and other alignment tools can be used. Capacities from 60,000 to 400,000 pounds...

Powered Fit-up Rolls Koike Aronson Ransome's Powered Fit-up station provides a easy economical way to fit up long vessels with multiple sections. With Individual powered adjustment for each wheel, under load, the sections can be moved left, right, up or down to be aligned to the next section. The addition of a manual or powered car allows the section to then be butted to the next for tacking. Once tacked, a powered drive roll sized to rotate the entire vessel is used for final weld-out. JOINT BEING WELDED POWERED MOVEMENT VERTICAL AND LATERAL MOVEMENT OF VESSEL WITH POWERED WHEEL ADJUSTMENT...
