Gearless Machine Room Less Lifts

Five to eight lengths of wire cable, known as hoisting ropes (or wire ropes), are fastened to the top of
the elevator and looped around the drive sheave, in particular grooves in a gearless traction machine.
The wires' other ends are connected to a counterweight that goes up and down on its own guide rails in
the hoist path. The cables are pressed into the grooves of the drive sheave by the combined weight of
the elevator car and the counterweight, providing the necessary traction as the sheave revolves.
 
The counterweight is estimated to match the weight of the automobile and a half-load of people to
lessen the burden on the motor. The counterweight drops as the automobile climbs, balancing the
burden.
