Do gearless elevators have a machine room?

Geared and Gearless Traction Elevators with Machine Room They are used for mid and high-rise applications and have much higher travel speeds than hydraulic elevators.

What is the major difference between geared elevator and gearless elevator?

The main difference between them is the standing of the wheel. On geared traction elevators, the wheel is placed at the machine room which is above the elevator shaft, while on gearless traction elevators the wheel is above the cabin and moves with the cabin.

What is gearless traction machine?

Definition of gearless traction : traction without reduction gears (as in a high-speed electric elevator drive in which the driving sheave is mounted directly on the armature shaft)

How does a gearless elevator work?

Gearless traction elevators have a very high travel speed i.e. up to 2000 ft. These elevators function using a wire cable (hoisting ropes) which is attached to the elevator top and wrapped around the sheave on one end. The other end of the cable is attached with a counterweight that raises and lowers in the hoist way.

Why do elevators use counterweights?

The purpose of a counterweight is to make lifting the load faster and more efficient, which saves energy and is less taxing on the lifting machine. Counterweights are often used in traction lifts (elevators), cranes and funfair rides.

How do MRL elevators work?

Similar to Overhead Traction Elevators, MRL Traction elevators are driven by an electric motor that is connected to a series of cables and sheaves. These cables connect to the elevator cab and counterweight frame and move over an electric drive sheave therefore creating vertical movement of the cab.

Which of the below is considered a benefit of a MRL elevator?

More Energy Efficient MRL elevators use 70\% to 80\% less energy than standard hydraulic elevators. That is a huge energy cost saving. In addition, the traction MRLs do not use oil, reducing costs and fire hazards.
