Suitable for welding in various shapes and sizes with Submerged Arc Welding techniques.
Circotech is a series of self-propelled 3 o’clock welding equipment primarily developed for on-site
erection of large storage tanks, silos, blast furnaces and similar cylindrical objects.
Usually it is designed ways of building tanks, one machine in the series is designed to travel on a rail
which is temporarily fixed to the shell or on a stand – alone ring outside the shell.
it is available as a single -side version and a double - side version.
The operator of each machine (if a double-side version) rides in a cabin, where he supervises and
controls the welding process with the control panel within easy reach.
The cabin, whose floor level under the carriage is variable to suit the height of the plate, is built as
a cage to give the operator(s) maximum safety and comfort.
For Weather protection the cage can be covered by curtains.
the cabin of a double -side machine is equipped with step ladders and a joining bridge at the top to
facilitate for the operators to climb onboard.
It is easy to adjust the machine for different plate heights, because of the telescopic design of the
frame.
the design also makes it easy to transport.
