A Betox 100 going up.

Mast root section of a brand new Betox 100 in 1974. There are two different mast sections: normal and reinforced. All outside dimensions are same, but the wall thickness of RHS tubes are bigger in reinforced sections. To identify these sections, normal sections are painted yellow, reinforced are black.
(Sections are 5 m long, cross section is 1.8 m)

Yes, the hoisting winch is there and the rope goes along the centerline of the mast. This causes difficulties when telescoping, so for that time the cable is led along a different route, outside the mast.
- Pingon P200 and their smaller models, too, had this same idea, but their telescoping system is different: mast sections are "wrapped" around the raising section (like Weitz), so it causes no problem.
