Supported rotator with step adjustment OVRS-20 U3 with load capacity of 20 tonnes (20 000 kg) is designed for installation and rotation of cylindrical products (oil tanks, cisterns, boilers) of various diameters with welding speed at automatic, semi-automatic and manual electric arc welding.
OVRS consists of driven and non-driven pairs of rollers (optional combinations of 2 non-driven pairs and 1 driven pair, 3 non-driven pairs and one driven pair), drive system, control system. When the supports are mounted on the rails, a special clamping fixing is provided for possible change of the distance between the supports.
With the help of OVRS it is possible to perform automatic welding of external and internal ring seams of products, as well as cladding of external and internal surfaces, additionally using welding columns or other mechanical devices.
The main advantages of OVRS rotators:
1. Setting the distance between the OVRS rollers to the required diameter of the product to be welded os...
