In present-day construction, the trend is to optimize space and energy efficiency. The Machine Room Less (MRL) elevator represents an ingenious solution because there is no longer a need for a dedicated machine room, thus benefiting the facility both in terms of efficiency and cost savings. However, what is an MRL elevator, and what are its growing attractions? We will find out.
An MRL elevator, or machine-room-less elevator, is a traction elevator with the traction machine and controller mounted in the hoistway as opposed to within an adjoining machine room. This arrangement allows greater space efficiency and energy saving.
MRL elevators use a geared traction machine that actually moves the elevator car by pulling steel cables that are attached to a counterweight. The machine is strung at the top of the hoistway-that is all there is to this practical, simple solution.
In 1996, KONE Corporation introduced MRL elevators with the MonoSpace® system. This innovation presented a real turning point in the technology of elevators by removing the machine room and increasing efficiency and sustainability.
| Feature | MRL Elevator | Traditional Elevator |
|---|---|---|
| Space Requirement | No machine room needed | Requires a separate machine room |
| Energy Efficiency | High (up to 30% savings) | Moderate to high |
| Installation Cost | Lower | Higher due to additional space requirements |
| Maintenance | Lower due to fewer moving parts | Higher due to more components |
| Suitable For | Low to mid-rise buildings | Mid to high-rise buildings |
Machine Room Less elevators provide a contemporary, energy-efficient, and space-saving solution to conventional elevators. Their compactness, sustainability, and dependability make them a number one choice for numerous buildings. If you need an elevator system that optimizes space and minimizes operational costs, the Machine Room Less elevator is a good investment.
