Until the late 90s, elevators required a dedicated machine room – typically located above the hoistway. It consisted of the controller, the motor, electrical disconnects and the pump unit. While these conventional traction and hydraulic elevator systems were more economical to install and widely used, they consumed more energy and required significant overhead space or a separate room (usually on the first floor). It made them less practical for low-rise buildings or buildings with limited spaces.
The introduction of MRL (Machine Room Less) changed the course of elevators functioning for the good. Compared to their counterparts, MRL elevator was designed with smaller sheaves and a machine that could be mounted within the hoistway itself. It allowed them to be installed in small and mid-rise buildings.
A Few Facts about MRL elevators
MRLs are ideal for small spaces
One of the key benefits of MRL elevators is their space-saving design. Because the electrical components, motor and other components can be directly installed into the electric shaft, it saves valuable space and allows architects to utilise the extra space accordingly. In addition to that, old, small and mid-rise buildings such as homes, complexes, and hotels can have the elevators installed for efficient vertical transportation without compromising on the floor space.
MRLs are low-maintenance
Elevator technology has come a long way with the introduction of MRL elevators with their advanced engineering and durability. MRL elevators have a simplified design, and due to the absence of a machine room, maintenance of MRL elevators becomes easier. Also, because of their design coupled with robust materials and components, technicians can identify issues promptly. And with fewer components involved, repairs become easy and quick.
MRL elevators are energy-efficient
Many MRL elevators today incorporate regenerative drives that capture and recycle energy generated during ascend and descend and transmit it back to the power grid. It indicates their energy efficiency and helps reduce the strain on the elevator system, further improving their lifespan.
MRLs are known for low-noise operation
Other than the machine room located within or on the top of the hoistway, MRL elevator cabs are designed with advanced anti-vibration technology and noise-isolation frames that deliver a smooth ride. Also, they operate at low decibel levels, resulting in a quiet building environment and a more comfortable ride for the passengers.
MRL elevators are efficient and safe
Elevator technology has improved and refined over the years. Modern MRL elevators come equipped with cutting-edge technology, such as advanced door controls, Elevator Call Systems or Mitsubishi Electric India’s DOAS (Destination Oriented Allocation System) technology, which allocates lift cars to passengers based on their destination.
As cities are slowly expanding and architectural designs are becoming more intricate, the incorporation of elevator in Bangalore, Mumbai, NCR, Hyderabad, and pretty much every metropolitan will play a pivotal role in shaping the future of vertical transportation.
