The universal welding positioner (rotator) is designed for secure fixation, lifting, rotation, and tilting of metro wagon frames into the most convenient position for welding operations. This equipment enables operators to quickly and safely handle large-sized metal structures weighing up to 6 tons and up to 24 meters in length, providing optimal access to all welds — both internal and external. It significantly improves welding quality, reduces labor intensity, and minimizes risks to personnel.
Advantages of Use
- Increased productivity: reduces the time required for repositioning the workpiece by 3–5 times compared to crane usage.
- Welding quality: all seams are performed in the flat or optimal position — this minimizes defects, spatter, and internal stresses.
- Ergonomics and safety: the operator does not work at height, eliminating the risk of heavy structures falling.
- Versatility: quick changeover for different frame sizes (from short to maximum length — 24 m).
- Reliability: the equipment is made of high-strength materials and designed for intensive use in railcar production conditions.
- Resource savings: reduces the load on the workshop’s crane equipment and minimizes downtime.
