Essential guide to MRL Elevator Machines

There is more confusion among people about the difference between MRL and home Elevators because MRL elevators are used in houses, too.

This post will guide you to consider these points before buying machine room less elevators in India.

Equipment required to install MRL elevator machines

1. Headroom

You will require a headroom of about 4.8 meters or 4800 mm or 16 feet in the MRL elevator.

2. Pit

The pit depth required for MRL elevators is 1.6 meters or 1600 mm or 5 feet approximately.

3. Minimum Floor Height

You will require a minimum floor-to-floor height of 2.5 meters or 2500 mm or 8 feet approximately in the Machine Room Less elevator.

4. Motor

The motor required for MRL elevators is a 3-phase motor. The customer has to give a 3-phase power supply.

MRL Elevator Machines India

Machine room less elevator machines India is attaining more rage among Indians. The MRL elevator machines in India also exports their products.

Some of the famous companies of MRL elevator machines India are,

●     Spire Elevators - New Delhi

●     Mobility Aids Sales and Services - Bengaluru, Chennai

Evolution of MRL elevator machines

People in the US wonder how these MRL elevators are different from other elevators like geared traction, gearless traction, and hydraulic elevators.

If you are looking for MRL elevators, then look at this buying guide before you buy.

The MRL elevator is different because this elevator doesn't need a machine room to board the motor. But you will find the motor in the hoistway. The motor is placed above or below the shaft.

Though the motor is sheltered within the hoistway, the electricians will find it difficult to repair if any damage occurs. So, the electricians should give the training to repair MRL elevators.

Whether it is a traction elevator or hydraulic elevator, or geared and gearless elevator, all these elevators look alike and travel using steel cable. Still, there is a difference in the functioning of elevators. MRL elevators use a Permanent Magnet Motor that doesn't require a specific room for the motor.

History of the MRL elevators

In 1996, Kone was the first person who discovered MRL elevators. MRL elevators were built to save more space particularly. Because of this evolution, MRL elevators benefited small buildings and medium-sized apartments.

The MRL elevators are becoming famous worldwide, except in America, in the past few years. But these days, America also started to install Machine-Room fewer elevators.

Consider the below criteria when you think of MRL elevators

1. No. of Floors

MRL elevators serve upto 30-35 floors. There are no particular limitations for Machine Room fewer elevators.

2. Passenger Capacity

What is the capacity of MRL elevators?

It is essential to know the limitations of passengers. It can provide space upto 24 passengers (3.5 tons).

3. Speed

According to MRL elevators, you can go up to 35 floors, and the speed you can travel is 2.5 meters per second (MPs).

4. Travel

Travel is the distance between where you start the elevator and where it stops.

For example, if your lift travels from the ground floor to the tenth floor, the distance between the ground floor's bottom slab and the tenth floor's bottom slab is called travel. MRL can travel up to 100 meters per second or maybe above that depending upon the new technology which is coming up.

5. Application

MRL elevators can be used in residential buildings, in a ground plus four buildings, in a ground plus 20 buildings, and it can be used upto 35 floors buildings.

It can be used in factories, commercial buildings, Malls, Hospitals, and more.

It also works on 3 phase power Supply.

Consider these 6 Points before accepting work to install the lift

There are six crucial points that sales executives or sales engineers from elevator industries should take care of. Because if they don't keep an eye on these things, it can lead to a blender scam.

●     Floor to floor Measurement

●     Exact measurement of the space where lift need to be installed

●     Sales engineers should not randomly assume the measurements

●     Have a look at the blueprint of the building

●     Consult with the client about the building

●     Go and visit the site

Case study

Consider a sales engineer assuming a random calculation of the site or if their client says they don't know the measurements. Then you have to take the measurements of the building site, and all the responsibilities go to the Sales engineer and installation engineer. Floor to floor height is significant when it comes to MRL elevators.

It is necessary to know about the measurements of the building site for the sales and installation engineers.

Even after you have a blueprint or a sketch of the building provided by an architect, mistakes can happen, so as a sales engineer y, you need to take care of a few things.

In this case, the sales engineer didn't measure the floor-to-floor height, and he just assumed it was 3 meters, then the blueprint of the building was ready, materials also came to the site. After the materials reached, they came to know about a floor that measured only 2.4 meters, and since the door required 3-meter space, He cannot install the door of MRL elevators.

Because of this blender mistake of a sales engineer, the whole case got messed up. Then the client started to blame the sales engineer. So before designing or installing MRL elevators, it is essential to measure the heights of the floors; otherwise, there will be a lot of arguments between the company and the clients, delays in the project, and money loss.

From this case study, the learning is that the sales engineers must know the exact measurements of the floors.

Conclusion

From the above information, you would have understood how to install MRL elevators and what are all the things to make a note of before installing Machine Room less elevators in your place! Also, it would be best if you gave the work of installing to the best planners of MRL elevator constructors.
