Welding Rotator

Product Details:

Welding rotator is a mechanical mean to rotate cylindrical vessels. Welding rotators minimize handling, increase efficiency, and dramatically improve the quality of workmanship from welders of all skill levels. Sabari enterprises can supply conventional and self-aligning rotators to suit various sizes of weldments across a variety of sectors. Any steelworks with cylindrical vessels, be it small diameter piping to large industrial cylindrical vessels for windtower production, a rotator will be beneficial, sometimes a necessity. If the weldment is cylindrical, a rotator will make a huge difference to most welding processes including, SAW, TIG, MIG and ARC. We manufacture rotators from 1ton capacity upto1000 Tons capacity as per customer requirement.


Features :1)Steel rollers or polyurethane lined rollers.2)Our standard Rotators consists of Drive Unit and Idler Unit.3)The frame and roller brackets are fabricated from heavy sections & precision machined.4)Variable surface speed from 300 to 1500mm/m or as per customer requirement using AC Variable Frequency Drives.5)For precision movement encoder feedbacks are provided on case to case basis.
Advantages :-1)An indispensable tool for shell fabrication shops.2)Attains exceptional Quality circumferential joints on shells.3)Increased production with reduced labour skill.4)Leads to minimum handling the shell / Job.5)Lesser usage of crane reduces idle time.6)Improves plant efficiency.

Product Details:

Self Aligning Rotator construction such that the trunnion brackets which support the wheels automatically align themselves when changing from one diameter to another, no manual adjustment whatsoever is required.Each section supports the vessel / Job on four points ensuring better traction, and on machines of 3 T to 500 T capacity and upwards 50 metric tonnes all four wheels of the drive section are positively driven. This four point suspension is an added advantage when on handling thin walled vessels.The two top leading wheels of the drive section incorporate clutches which are loosened prior to loading the vessel and the top wheels can rotate freely when the vessel is loaded; thus regardless of weight if the vessel is lowered centrally between the frames, or firstly on to one wheel only, no damage can be sustained by the transmission.

Product Details:

Conventional Rotators are built in capacities from 1T To 2000 Tonnes. The frame is of robust fabricated construction and is machinened on the top and underneath to ensure perfect alignment. Both the drive and the idler frames are provided with robust fabricated and machined wheel brackets which support the axles and bearings of the rollers.According to capacity the Rotators are provided with all Polyurethane wheels with overload disc and all steel wheels.The Rotator base fabrication, or chassis, is designed and fabricated to carry the weight of the vessel / Job and incorporates a contingency for shock loading. It is important that the design eliminates any distortion which can lead to misalignment of the rollers. The drive section comes under the biggest strain when the vessel /Job is being loaded. It is physically impossible for a crane operator to position the vessel so that it contacts with both sets of rollers at the same time. If the work-piece one roller before being supported on all the rollers, the first roller will receive a full shock load which puts a considerable force on to the drive. We have endeavored to incorporate a good overload margin to absorb this shock load.
