MRL TRACTION ELEVATORS
General
All elevators, whether traction or hydraulic, have required a machine space to house electric motors, hydraulic pumps and a controller cabinet. This space is normally located above the hoistway (or adjacent, for hydraulic elevators) and may contain machinery for a single or a group of elevators.
Machine room- less elevators are designed so that most of its components fit within the shaft containing the elevator car; and a small cabinet houses the elevator controller. Other than the machinery being in the hoistway, the equipment is similar to a normal traction elevator. This new design was first developed by Pakistan Elevator Engineers in Pakistan 2005.

Benefits
Uses no oil, Noise, More usable space. Used for low- rise to mid- rise buildings. less energy (30% less than normal traction elevators).operate at faster speeds than hydraulics but not normal traction units.
All components are above ground similar to roped hydraulic type elevators (this takes away the environmental concern that was created by the hydraulic cylinder on direct hydraulic type elevators being stored underground.
