Traction and Hydraulic Elevators: Everything You Need to Know

An Explanation From Triad Lifts, LLC.

Elevators have become an essential part of modern life since they were invented in the 1800s, transporting people and goods between different floors of a building. Most elevators you come across will be in two main categories of elevators: traction elevators and hydraulic elevators. Traction elevators are the most common type, using cables and counterweights to move the elevator car up and down. Hydraulic elevators, on the other hand, use a piston to raise and lower the elevator car. Both types have their advantages and disadvantages. Traction elevators are more efficient and can travel at higher speeds, but they require more space and are more expensive to install. Hydraulic elevators, on the other hand, are less expensive and take up less space, but they travel more slowly and are less energy-efficient. Ultimately, the type of elevator that is best for a particular building depends on a variety of factors…

Traction Elevators

A traction elevator is a type of elevator that uses ropes and pulleys to move the car up and down. The ropes are attached to a counterweight, which helps to balance the car and reduce the amount of energy needed to move it. The pulleys are mounted on a sheave, which is a large wheel that helps to guide the ropes and keep them from getting tangled. The car is also equipped with brakes that prevent it from moving too fast or falling. Traction elevators are typically used in high-rise buildings, where they can provide efficient and reliable service.

Hydraulic Elevators

A hydraulic elevator doesn’t use overhead machinery, but instead is a type of elevator that uses fluid to raise and lower a piston that the elevator cab is attached to. One main advantage of hydraulic elevators is that they are very powerful and can heavier loads. While they are limited on how far they can travel due to the piston and cylinder, they are more affordable to install compared to traction elevators. Hydraulic elevators also cost less to repair and maintain them which can make them more favorable for smaller buildings.

The Pros and Cons

Choosing which elevator to go with depends on the application. Below we will go over some of the pros and cons of each type of elevator.







Now you have a better understanding of the two main types of elevators: traction and hydraulic. Both have their own advantages and disadvantages, so it’s important to choose the right one for your needs. Traction elevators are powered by electric motors that drive a system of pulleys and cables and have machine room less options. These pulleys and cables are what actually lift the elevator car. Hydraulic elevators, on the other hand, use a hydraulic piston to raise and lower the car. While hydraulic elevators are typically cheaper and easier to install than traction elevators, they are not as energy efficient and can be less reliable. When choosing an elevator for your building, be sure to weigh all of the factors before making a decision.
