Machine Roomless Lift - Space-saving Design, Low Noise Operation, High Energy Efficiency, Minimal Maintenance Costs

The machine room less (MRL) elevator eliminates the need for a machine room in the building. For almost 100 years, lifts have been packaged with a special space in a building for the location of machine and lift related equipment such as the controller and the over speed governor. This space, called machine room, was usually located in the top of the building for traction lifts and in the bottom of the building for hydraulic lifts. The concept of MRLs is that all equipment are located and accommodated within the lift well or in a special cabinet nearby the well. This fact allows building constructors and architects to save space and related costs in the building. Electric traction arrangements are mount the machine directly on the guide rails, while others adopt a bed plate arrangement built into the well structure. For hydraulic MRL lifts the drive unit may be placed in the pit area or in a cabinet located in the vicinity of the lift well. The controller is usually located at either the top or bottom lift landing next to the lift door, but can also be located within the lift well.
