Machine Room Less Elevator: What You Need to Know

In recent years, the development of the elevator industry has changed from machine-room elevators in the past to machine-room-less elevators. The MRL elevator is not a simple partial improvement to the traditional elevator of the past, but a major change in elevator technology. This is because some key technologies used in machine-room-less elevators will be applied to other elevator products, driving the development of the whole elevator industry. So today we will discuss what is a machine-room-less elevator.

What is a machine-room-less elevator

A machine-room-less elevator is an elevator that does not require an enclosed special room for the installation of the main elevator drive, control cabinet, speed limiter and other equipment. In order to save space, the machine room-less elevator installs the control cabinet, main unit, speed limiter and other equipment that used to be installed in the machine room above the shaft in the shaft instead, eliminating the special machine room setting and effectively increasing the floor space utilization rate while reducing the construction cost. The small gearless mainframe and 2:1 traction system are used for transportation, eliminating the noise in the machine room caused by traditional gear meshing. The thin control cabinet is installed in the shaft near the first floor, so that installation and commissioning, data reading and writing, daily maintenance and passenger rescue can be carried out quickly and conveniently through off-hall access while effectively waterproofing, and the minimum thickness of 130 mm saves the maximum space in the shaft.

Since mrl elevators do not have a machine room, their control system has higher flexibility, convenience and reliability compared with ordinary elevators.
