摘要

Lifting apparatus consisting of a traction system and of a balancing system. The traction system consists of a motor (M), a deviation pulley (PD) and a set of traction cables (FT). The traction cables (FT) are firmly connected to the counterweight (CP); they start from point 1, wind to the driving pulley (PM), extend vertically along the hoistway and, by means of the deviation pulley (PD), descend again onto the counterweight (CP) at point 2. The balancing system consists of a cabin (C), a counterweight (CP), a pulley (PB) and a set of balancing cables (FB). The balancing cables (FB) start from point 3 located at the top of the cabin (C), extend vertically on the deviation pulley (PD) and descend to point 4 on the counterweight (CP). <IMAGE>
