Machine Room (MR) Elevators

Machine Room (MR) Elevators are traction elevators that are becoming the most common choice of mid rise buildings. These are explicitly designed to fit in small spaces, consume less energy and yet deliver smooth and safe operation in combination with Beacon’s advanced control & drive system technology.

MR is a new design concept that is now being widely accepted. As the name implies, the elevator does not require any machine room space as the machine and other related equipment are installed inside the shaft. The technological advancement & innovation has led to further benefits like, low construction & maintenance cost and creating more usable space. It is an ideal solution for low, high rise, new & existing buildings.

ELEVATOR OPERATIONS

SINGLE AUTOMATIC OPERATION

Automatic operation by the means of the button in the car for each landing level served and one button at each landing so arranged that if any car or landing button has been actuated, the actuation of any other car or landing operating button will have no effect on the movement of the car until the response to the first button has been completed.

DOWN COLLECTIVE AUTOMATIC OPERATION - ONE CAR (SIMPLEX)

The car stays at the main floor, which has an 'UP' button; upper floors have 'DOWN' button. The controller memorizes landing and car calls. Ideal for residential buildings, the car travels to the highest landing call, stopping at car calls only while going up. On the way down, it stops at all calls in sequence.

DOWN COLLECTIVE AUTOMATIC OPERATION - TWO CAR (DUPLEX)

Operates like the Simplex system, but with two cars: one parks at the main floor, the other at the top or midway if last stop was the main floor. When a call is received, the microprocessor sends the nearest car. For multiple calls, a car goes to the highest, then serves in downward sequence.

ELEVATOR DESIGNS

1:1 Suspension System

1:1 roped. Single wrap. Generally restricted to 30 meters. The most straightforward is considered a 1:1 roping arrangement in which the movement of the roping members and the corresponding amount of movement of the elevator car is the same. 1:1 roping offers equal rope and car speed, ideal for medium to high-speed elevators but needs a diverter for layout flexibility.

2:1 Suspension System

In a 2:1 roping arrangement the roping members movement is twice as much as the corresponding movement of the elevator car.
2:1 roping doubles load capacity by moving the rope at twice the car's speed.

4:1 Suspension System

4:1 roping arrangements have been proposed and include roping member movement that is approximately four times as much as the corresponding movement of the elevator car.
