The tower shall be lifted into position A and then (manually) lowered by horizontal screws into vertical position. The assembly rope shall be winded on winch drum for further operations.

When the tower is lifted into vertical position telescoping part should be extracted for further assembly.
Telescoping is performed by slewing mechanism which is equiped with toothed coupling. During the telescoping phase upper rotating part of the crane should be fixed and the coupling switched into position 2. Slewing mechanism then rotates the screw, nut is fixed on a cross beam which leans on fixed part of the tower.
