Traction elevators often need to be modernized to improve performance, enhance safety, and to integrate more up-to-date technology. Upgrading critical parts of a traction elevator can make a world of difference for you and your elevator riders, while also potentially increasing the value of your building.
TYPES OF TRACTION ELEVATORS
Traction elevators are the most common type of elevator and can be geared or gearless. Both geared and gearless traction elevators are driven by alternating current (AC) or direct current (DC) electrical motors. In geared elevators, a worm gear is used to control the mechanical movement of the car. This is done by rolling steel hoist ropes over a drive sheave. Geared machines can reach speeds up to 500 feet per minute. Gearless traction elevators have a drive sheave that is directly attached to the end of the motor and can reach speeds up to 2,000 feet per minute.
