MRL Elevator (Machine Roomless Elevator)

Applications:
Our MRL elevators have the characteristic of being convenient and needing less-frequent maintenance. As a result, they are good passenger carrying vehicles for various multi-floor buildings like residential buildings, office buildings and shopping malls, etc.

Specifications:

Mode Structure Driving / Traction Speed (m/s) Loading (kg) Max Travel (m) Traction Machine Location
MRL-01 MRL VVVF Gearless motor 1.0/1.6/1.75/ 450/630/800/1000 75m Inside shaft
MRL-02 MRL VVVF Gearless motor 1.0/1.6/1.75 1350/1600/2000/3000 75m

Features:
A machine roomless elevator is not only a vertical transport vehicle, but also an elevator that incorporates advanced technology in the lift manufacturing industry. we use this advanced technology to satisfy passengers by ensuring comfort.

MRL elevators are designed based on a combination of architectural practicability and building individuality. They are therefore the best choices for real estate. Additionally, our effective consultation, planning, manufacturing, installation and maintenance teams will help customers to save much expenditure and time.

Performances:
Compared to traditional elevators, the MRL elevator has overwhelming advantages, such as narrow shaft area, convenient installation, low cost, energy saving, environmentally friendly, and simple and easy maintenance.

a. Our permanent magnet synchronous gearless traction device uses technology that saves energy by over
40%. The gearless traction machine is characterized by low friction and low maintenance costs.
b. Our MRL elevator combines a 32bit microcomputer control system, Variable-Voltage and Variable-
Frequency (VVVF) control and serial communication, which enables the whole lifting system to be
accurate, reliable, stable and safe.
c. The traction machine and control system can be installed on every floor. This drastically reduces structural
difficulties.
d. The traction machine and guide rail run with low levels of noise production.
