Upper Double Sheave Frame

The Upper Double Sheave Frame consists of a steel structure with two sheaves installed at the top of the elevator cabin. This yoke securely holds the suspension cables and, by being positioned parallel to the guide rails above the cabin, contributes to the stability and safety of the elevator.

What is a Yoke?

A yoke, also known as a car frame, is one of the main mechanical components of an elevator, playing a key role in force transmission and movement.

Typically made from high-strength metals, the yoke serves as the central axis or main structural frame between the elevator cabin and the lifting system.

The yoke works in conjunction with the suspension cables and the elevator motor to ensure stable and safe movement of the cabin along its path. Yokes consist of three main sections: upper yoke, lower yoke, and side yoke. In Cabin Plus, each section is precisely and fully engineered to enhance cabin performance and safety.
