AI Technical Summary
Technical Problem
The installation of a new hoisting machine in conventional elevator systems is time-consuming due to the need for multiple connections to the guide rail via sway rests.
Method used
The elevator device incorporates a first hoisting machine with a sheave shaft and a second hoisting machine that includes a sway stopper to prevent rotation relative to the first hoisting machine, allowing for easy installation by supporting the vertical load at the sheave shaft and utilizing the first hoisting machine's fixing structure.
Benefits of technology
Facilitates quick and efficient installation of the second hoisting machine, reducing the renovation time and number of parts required, while providing stability during earthquakes.

Abstract
In this elevator device, a first hoisting machine has a sheave shaft and is installed in a hoistway. A second hoisting machine has a second hoisting machine body and a second driving sheave. A suspension body is wound around the second driving sheave. A vertical load that is exerted from the suspension body on the second hoisting machine is supported by the first hoisting machine at the sheave shaft. The second hoisting machine is further equipped with a steady rest. The steady rest is in contact with the first hoisting machine and prevents the second hoisting machine body from turning about the sheave shaft with respect to the first hoisting machine.
