Traction Elevators: A Deeper Dive

Written by Ryan Gressett

Traction elevators are the most common type of elevator used today. They utilize a traction machine and steel cables to lift and lower the elevator car. Here are some additional facts about traction elevators:

• Traction Machine: The traction machine is the heart of a traction elevator. It consists of a motor, sheave, and brake. The motor drives the sheave, which in turn pulls the elevator car and counterweight using steel cables.

• Counterweight: The counterweight balances the weight of the elevator car, reducing the load on the traction machine and improving energy efficiency.

• Governor: A governor is a safety device that prevents the elevator from exceeding its maximum speed.

• Car Safety Devices: Traction elevators have various safety devices, such as car bumpers, limit switches, and safety gears, to prevent accidents.

• Types of Traction Elevators: Traction elevators can be classified into gearless and geared types. Gearless traction elevators are known for their smoother operation and higher efficiency, while geared traction elevators are more common in older buildings.
