Geared - Pakistan Elevator Engineers

GEARED TRACTION ELEVATORS
Geared traction machines are driven by AC electric motors. Geared machines use worm gears to control mechanical movement of elevator cars by "rolling" steel hoist ropes over a drive sheave which is attached to a gearbox driven by a high speed motor. These machines are generally the best option for basement or overhead traction use for speeds up to 2.5 m/s & height 90 meters.
