The technology used for vertical transportation is advancing and evolving rapidly. Traction elevators are the outcome of this advanced technology, and they have emerged as the key player that allows older people and people with mobility issues to access the upper floors of a high-rise building. This post discusses the main functionality of these traction elevators, and we will also go through the pros and cons.
WHAT IS A TRACTION ELEVATOR?
The traction lift offered by any elevator service company is also referred to as a cable lift, counterweight lift, or rope lift. The main components of a traction elevator are –
Cables or ropes
A sheave or pulley
Counterweight
Motor
Some traction lifts also have gears between the motor and the sheave, while some lifts are directly connecting the motor and the sheave. The cable ropes are made from solid stainless steel for enhanced safety. These cables ensure that even if the strand breaks fail, the cable will be there to hold the cab.
WHAT IS THE FUNCTIONING OF A TRACTION ELEVATOR?
The overall functioning is effortless to understand as the motor is attached to a sheave with the help of a rope or cable. This rope is attached to the lift on one end and the counterweight on the other end. Upon getting a call, the motor turns the sheave, and this motor can move in both directions to move the cab up and down. The cab rises upwards, and the counterweight goes downwards, and vice versa. This counterweight is present to lower the pressure or strain on the motor. This translates into lesser power consumption and better stability. These elevators also come with an overspeeding governor to monitor the speed of your traction elevator.
WHAT ARE THE BENEFITS OF USING TRACTION ELEVATORS?
The traction lifts offered by an elevator service company will come with several benefits or advantages over other types. For example – they are more reliable compared to hydraulic lifts as they come with fewer mechanical parts. There is no fluid system involved in traction lifts, and this means fewer chances of any breakdowns or faults. They are also less space-consuming than hydraulic lifts and require additional space to store oil in reserve. Moreover, traction elevators are faster than hydraulic lifts, and this makes them ideal for high-rise buildings. Safety systems are also believed to be better in traction lifts than hydraulic lifts. They come with an overspeeding governor to prevent the cab from overspeeding or falling.
