Abstract

The hoist rope (1) is reeved round a pulley block (3) so as to form two runs, and the pulley block is attached to the erection winch rope (4). The weight of this pulley block keeps the hoist rope right, even whent he hook is lowered to touch the ground. The hoist rope tends to raise the pulley block (3) and the erection winch rope (4e raises the tower by means of the tension exercised between the base (6) and rope (4) by pulley system (7). a load on the hook produces a lower but proportional load on the pulley system (7).
