How Are Lifts Powered?
Though we might not think about them often, the ubiquitous lift forms a vital cog in how our modern civilization runs. How would a modern built-up city operate without this essential but little-appreciated piece of technology? The humble lift lubricates our working day, saves us precious hours and provides vital transportation for disabled people.
But do you have any idea how lifts are even…lift? Here are the three ways that lifts are operated:
A hydraulic lift is a lift that uses technology based on the use of liquid. There are three basic types of hydraulic lifts used in the world today:
Conventional elevators – These are usually used in buildings up to five floors high and employ an underground hydraulic cylinder.
Holeless hydraulic elevators – These employ two cylinders based above the ground and are usually used in buildings that have up to four floors.
Roped hydraulic elevators – These lifts use a rope system combined with a cylinder that is situated above the ground.
Hydraulic lifts are generally simpler and cheaper than traction elevators. They are, however, less energy-efficient as the lift has to work more against gravity, and also pose environmental dangers if the lifting fluid ever leaks into the ground. The hydraulic lift has been the standard lift type for decades but it is threatened by traction lifts due to there greater efficiency and its price gradually becoming more affordable.
Traction lifts either come in geared or non-geared types and are powered by electric motors. Traction lifts that use gears move the lift car by rolling metal ropes over a drive sheave which is connected to a powerful motor. Gearless machines have a drive sheave that is directly connected to the end of the electric motor. With both types, cables are connected to a plate on the top of the car and then looped over the drive sheave to a counterweight connected to the opposite end of the cables. This significantly reduces the electric power needed to move the car.
This is a type of life that offers an energy saving capability. It works similar to regenerative braking in automobiles by employing the lift’s motor as a generator to retain some of the gravity potential of the car descending or ascending.
