With Fewer Moving Parts And A Self-Contained Design MRL Elevators Are Easier To Maintain And Have A Longer Lifespan

Machine Roomless (MRL) elevators are a modern elevator design that eliminates the need for a separate machine room, making them a space-saving and energy-efficient solution for mid-rise buildings. These elevators integrate the motor and control system within the hoistway, typically at the top or bottom, optimizing building space while maintaining performance and reliability.

Key Features of MRL Elevators

1. Compact and Space-Saving Design

• Unlike traditional elevators that require a dedicated machine room, MRL elevators house the machinery inside the shaft, reducing the building's footprint.

• Ideal for buildings with limited rooftop or basement space, such as commercial offices, hotels, and residential complexes.

2. Energy Efficiency

• Most MRL elevators use permanent magnet synchronous motors (PMSM), which consume less energy than conventional AC motors.

• Regenerative drives can feed excess energy back into the building’s power grid, further improving efficiency.

3. Smooth and Quiet Operation

• Advanced gearless traction systems reduce noise and vibration, ensuring a comfortable ride.

• Suitable for noise-sensitive environments like hospitals and luxury residences.

4. Advanced Control Systems

• Equipped with microprocessor-based controllers for precise floor-leveling and faster response times.

• Can integrate with smart building systems for remote monitoring and predictive maintenance.

5. Safety and Reliability

• Complies with international safety standards (EN 81-20/50, ASME A17.1).

• Features include emergency brakes, backup power options, and door safety sensors.

Applications of MRL Elevators

• Commercial Buildings: Offices, retail spaces, and hotels benefit from space savings and energy efficiency.

• Residential Buildings: Ideal for apartments and condominiums where noise reduction is crucial.

• Institutional Buildings: Hospitals and schools use MRL elevators for their reliability and low maintenance.

STANDARD FUNCTIONS

FAQ
1. Are the elevator wire ropes durable?
The elevator wire rope has special provisions and requirements. Configuration is not only for wire rope and rated load, but also considered the size of the traction, as a result, the tensile strength of wire rope is greater than the weight of the lift. The safety factor is equipped with more than four wire rope. So it won’t break at the same time.
2. Is it dangerous for power failure suddenly during the elevator running?
If it occurs, the elevator will automatically stop due to the electrical and mechanical safety device. In case of power failure,elevator brakes will automatically taken. In addition, the power supply departments such as planned outage, prior notice are also operating.
3. Will us be hurt when it closed suddenly?
In the closing process, if people touch the hall door, the door of elevator will automatically restart without any danger. With anti clamping switch, once the gate touched, this switching action make the elevator unable to be closed and even reopened. In addition, closing force is also available here.
4. How the elevator running?
Elevators are operated with a counterweight wire rope through the (tractor) traction drive, making ups and downs on the guide rail.
5. Is the escalator installation complicated?
We believe the functions of an escalator are not necessarily proportional to the operation complexity. Therefore, escalators designed by us apply an integrated structure, so that the equipment is more precise and more efficient and allows easier and more convenient commissioning.
6. Do you have any cerifications?
Yes, we do with ISO9001 / CCC / CE Certificates for u.
