The Ultimate Guide to Elevator Traction Machines

Elevator technology has come a long way since its inception, with significant advancements being made in efficiency, safety, and design. Among these innovations, elevator traction machines have played a pivotal role in shaping modern vertical transportation systems. In this comprehensive blog, we’ll delve into the world of elevator traction machines, exploring their types, working principles, benefits, and highlighting the expertise of MAS Industries, a leading name in elevator traction machines.

What is an elevator traction machine? 

An elevator traction machine is a motor that drives the elevator car up and down. It is located in the machine room, which is usually located at the top of the building. The traction machine is connected to a sheave, which is a large pulley that the elevator cables are wrapped around. When the motor turns, it rotates the sheave, which moves the elevator cables up or down, depending on the direction of travel.

Different types of traction elevators

There are two main types of traction elevators: geared traction elevators and gearless elevator machine.

  • Geared traction elevators have a gearbox attached to the motor, which drives the wheel that moves the ropes. Geared traction elevators are capable of travel speeds up to 2 m/s. The maximum travel distance for a geared traction elevator is around 75 m.
  • Gearless traction elevators have the wheel attached directly to the motor. Gearless traction elevators are capable of speeds up to 20 m/s and they have a maximum travel distance of around 500 m so they are the only choice for high-rise applications.

In addition to these two main types, there is one more type of traction elevators:

  • Machine room-less traction elevators do not have a machine room above the elevator shaft. Instead, the motor and other equipment are located in the Well. This type of elevator is becoming increasingly popular because it saves space and is more energy efficient.

The type of traction elevator that is best for a particular building will depend on a number of factors, including the size of the building, the number of floors, the desired speed, and the budget.

Here is a table summarizing the key differences between the two main types of traction elevators:

How do traction elevators work?

A traction elevator is a type of elevator that uses a motor and a system of ropes to move the elevator car up and down. The motor is connected to a sheave, which is a pulley with grooves around the circumference. The ropes are threaded through the grooves of the sheave and attached to the elevator car and a counterweight.

When the motor turns, it rotates the sheave, which causes the ropes to move. The ropes then lift or lower the elevator car. The counterweight helps to balance the weight of the elevator car, so that the motor doesn’t have to work as hard.

Traction elevators are the most common type of elevator. They are used in buildings of all heights, from small office buildings to skyscrapers. They are also the most energy-efficient type of elevator, because they use less power to move the elevator car.

Benefits of Traction Elevators

Traction elevators offer numerous advantages, making them a popular choice for various building types:

  • Smooth and Quiet Operation: Gearless traction elevators provide a remarkably smooth and quiet ride due to the absence of gearboxes and the direct motor-to-rope connection.
  • Efficiency: Gearless traction elevators are more energy-efficient than their geared counterparts, contributing to reduced operational costs and environmental impact.
  • Space-saving: Gearless traction machines are compact and require less overhead space, making them suitable for tall buildings where space is at a premium.
  • Higher Weight Capacity: Traction elevators can accommodate heavier loads, making them ideal for transporting goods and larger groups of people.
  • Safety: Traction elevators are equipped with advanced safety features, such as emergency braking systems and backup power sources, ensuring passenger safety even during power outages.
