One of the most common questions asked by property developers and building owners across Africa is whether to go with a traditional traction elevator or a modern Machine Room Less (MRL) elevator. Both are excellent systems, but they are designed for different situations. This detailed comparison will help you understand exactly which type is right for your building in Nigeria, Ghana, or anywhere in West Africa.
Understanding Traction Elevators
Traditional traction elevators have been the backbone of vertical transportation in commercial buildings for over a century. They work by suspending the elevator cab on steel ropes, which pass over a grooved pulley (the sheave) driven by an electric motor located in a dedicated machine room — usually on the roof of the building. A counterweight on the other side of the ropes balances the weight of the cab, making the system remarkably energy efficient.
The machine room houses the motor, the drive controller, and safety equipment. Access to this room is restricted to qualified technicians and is an important part of elevator safety. Traditional traction elevators are well-proven technology with decades of performance data behind them.
Understanding Machine Room Less Elevators
MRL elevators take the core technology of a traction elevator and redesign it to fit within the shaft itself. The compact gearless motor sits in the upper portion of the shaft, and the control cabinet is mounted outside the shaft near the top floor landing. There is no need for a separate machine room above the building.
This innovation was a breakthrough for the building industry. It freed up valuable floor space that would have been used for a machine room — space that could now be used as a penthouse, rooftop terrace, or additional rentable area. MRL technology has matured significantly since its introduction and is now the preferred choice for most new mid-rise commercial and residential buildings worldwide.
Key Differences at a Glance
| Feature | Traditional Traction | MRL Elevator |
| Machine Room | Required | Not required |
| Shaft space efficiency | Standard | Better — no extra space needed above |
| Energy efficiency | High | Slightly higher (newer drives) |
| Installation time | Longer | Slightly shorter |
| Typical building height | 4-50+ floors | 2-25 floors ideal |
| Maintenance access | Easy (separate room) | More complex in shaft |
| Cost | Lower in tall buildings | Lower in mid-rise buildings |
| Africa suitability | Excellent | Excellent — especially for space-saving |
Performance in the African Climate
The hot and humid climate found in most of West Africa is an important factor when choosing an elevator type. Traditional traction elevators with machine rooms benefit from dedicated ventilation in the machine room, making it easier to keep the motor and drive system cool. MRL systems have their motor inside the shaft, which can be warmer, but modern MRL designs use advanced thermal management to compensate.
Dove Lifts specifies all its MRL systems with tropical-rated components and enhanced cooling to ensure reliable performance in Nigeria's climate. Their engineering team has extensive experience adapting international elevator specifications for West African operating conditions.
Cost Comparison in West Africa
The cost comparison between traction and MRL elevators in West Africa depends heavily on building height and the value of saved floor space. For buildings below 20 floors, MRL is often more economical when you factor in the cost of the machine room construction that is no longer needed. For buildings above 25-30 floors, traditional traction elevators with machine rooms may offer more cost-effective high-speed configurations.
Which Should You Choose
For most new commercial and residential buildings in Nigeria and West Africa — particularly those between 5 and 20 floors — an MRL elevator is the smarter choice. It eliminates the cost and space of a machine room, uses modern drive technology that is more energy efficient, and reflects current best practice in elevator installation worldwide.
For very tall buildings (30+ floors) requiring high-speed systems, traditional traction configurations may still offer advantages. And for low-rise applications of 2-4 floors, a hydraulic system may be more cost-effective than either.
Dove Lifts offers both traction and MRL systems across their entire product range and can provide expert guidance on the best choice for your specific building project.
Frequently Asked Questions
What is the main difference between traction and MRL elevators?
The main difference is that traditional traction elevators require a separate machine room above the shaft to house the motor and controls, while MRL (Machine Room Less) elevators house all components within the shaft itself, eliminating the need for a machine room.
Are MRL elevators more energy efficient than traction?
Modern MRL elevators typically use the same or slightly more advanced drive technology as traditional traction elevators. Both types can be fitted with regenerative drives that feed energy back to the building grid during descent. Energy efficiency is very similar between the two types.
What is the maximum building height for an MRL elevator in Africa?
MRL elevators are ideal for buildings up to 20-25 floors in most configurations. For very tall high-rise buildings above 30 floors, traditional traction configurations with machine rooms may be more suitable for high-speed, high-capacity requirements.
Is MRL elevator maintenance harder in Nigeria?
MRL maintenance requires access to components within the shaft rather than a dedicated machine room. This requires more skilled technicians but is not inherently more difficult. Dove Lifts trains all its technicians specifically on MRL maintenance procedures to ensure high service quality.
Which elevator type is best for a residential apartment building in Lagos?
For a residential apartment building in Lagos with 6 to 15 floors, an MRL traction elevator is typically the best choice. It saves the space that a machine room would have used, is energy efficient, quiet, and provides excellent ride quality for residents.
Conclusion
Both traction and MRL elevators are excellent choices for buildings across Africa. The right decision comes down to building height, available space, budget, and technical requirements. For most mid-rise buildings in Nigeria and West Africa, the MRL elevator represents the smarter, more modern choice.
