Abstract (en)

[origin: EP1961688A1] A car is provided with a first car suspending pulley and a second car suspending pulley, and a counterweight is provided with a first counterweight suspending pulley and a second counterweight suspending pulley. A first hoisting machine having a first drive sheave and a second hoisting machine having a second drive sheave are provided to a hoistway. The car and the counterweight are suspended within the hoistway by a main rope body having a first main rope and a second main rope. The first main rope is looped continuously around the first drive sheave, the first car suspending pulley, and the first counterweight suspending pulley. The second main rope is looped continuously around the second drive sheave, the second car suspending pulley, and the second counterweight suspending pulley. Thus, the first hoisting machine and the second hoisting machine can be reduced in size, respectively, so the space for the hoistway can be saved.
