Abstract:

A first car suspension sheave and a second car suspension sheave are provided at an elevator car, and a first balance-weight suspension sheave and a second balance-weight suspension sheave are provided at a balance weight. A first hoist having a first drive sheave and a second hoist having a second drive sheave are arranged in a hoistway. The car and the balance weight are suspended in the hoistway by a main rope body having a first main rope and a second main rope. The first main rope is continuously passed over the first drive sheave, the first car suspension sheave, and the first balance-weight suspension sheave. The second main rope is continuously passed over the second drive sheave, the second car suspension sheave, and the second balance-weight suspension sheave. The construction reduces the size of the first hoist and the second hoist and also reduces the space in the hoistway.
