Thanks a lot for the answer! I will write to your email.
I dont have whole mast, only inner section. We can repair it by local heating without the help of any press machine on our crane building plant. So we need only technical information of the geometry 0f the mast.

I do not know the machine but the settings are similar to all.
1st - we have to see the height of the mast below the ground, varies from 15-20 cm.
2 - see the support in the heats of the gap width between bearings.
3 - Watch the height of the maximum tilt forward and backward through the course of monkeys tilt for placement of the pins that secure the monkeys to the mast.
4 - see the maximum width of the mast and rotated between working width of monkeys tilt.
5 - see calculations for the dimensions of the profile or profiles to be used according to the tonnage or cargo maximum permitted according to the manufacturer of the profile to be used.
6 - do not forget the return valve in monkeys lift to descend gently, for without this was catastrophic. with a photograph or drawing of what you want I can help in any way, since I have done some things
