Elevators | Lifts

Elevators, or lifts, are vertical transportation devices that move people and goods to various levels and floors of a structure. Designed with a cab (also known as a car, carriage, or cage) that is either pushed or pulled vertically through space via a combination of machines and hoists, elevators are essential building technologies that facilitated the development of skyscrapers. Elevators are commonly distinguished by being either Traction Elevators that use hoist ropes or Hydraulic Elevators that are driven by a hydraulic cylinder.

Common Questions

Who invented the modern elevator?
Elisha Otis invented the ‘safety elevator’ in 1852 which was the first system that demonstrated that it was safe for passengers and widespread use in buildings.
When is an elevator needed?
The need for an elevator depends on the situation, but an elevator is typically needed when a building has three or more floors and is more than 3,000 ft2 | 279 m2.
What are the common types of elevators?
The two most common elevator types are Traction and Hydraulic Elevators. Traction elevators are raised and lowered by steel hoists, while hydraulic systems use pistons.

Traction Elevators are lift systems that use an electric hoisting machine and hoisting cables to raise and lower the elevator car vertically along guide rails. Traction Elevators are a common system for many mid-rise and high-rise structures and require a penthouse machine room and counterweight.

Hydraulic Elevators are lift systems that use a hydraulic piston to raise and lower the elevator car. Hydraulic Elevators are typically used for low and mid-rise buildings and have a hydraulic piston below the elevator pit and must be at least the overall rise plus 4’-7’ | 1.2-2.1 m.

Machine-Room-Less (MRL) Elevators are modern traction lift systems that uses an electric hoisting machine located within the top of the elevator shaft to hoist the elevator car. Machine-Room-Less Elevators travel at a speed of 500’ | 152 m per minute with a maximum distance of up to 250’ | 76 m.
