Machine Room (MR) Elevator
Elevator systems with a dedicated machine room — proven reliability, high load and speed capability, easy maintenance access.
A machine room (MR) elevator is a traction lift whose drive machine, controller and governor are installed in a dedicated room, normally directly above the hoistway. Nazar Elevator manufactures MR systems for rated loads of 320 to 2500 kg and speeds up to 4.0 m/s, in conformity with EN 81-20 and EN 81-50.
How does a MR elevator work?
The traction machine drives a sheave over which the suspension ropes run. One end carries the car, the other a counterweight that offsets the car weight plus roughly half the rated load. Because the machine sits in its own room, larger geared or gearless machines can be used, and noise and vibration are structurally separated from the shaft.
The controller cabinet, overspeed governor and main switch are installed in the same room, which makes inspection, adjustment and component replacement straightforward for the maintenance technician.
When should you specify a MR elevator?
- Buildings above roughly 15–20 floors, where speeds over 2.5 m/s are required
- Rated loads above 1600 kg — freight, hospital bed and vehicle lifts
- High duty cycle installations such as hospitals, hotels and offices with heavy traffic
- Modernisation of an existing shaft that already has a machine room
- Projects where the lowest possible equipment cost matters more than floor area
MR vs MRL elevator: full comparison table
| Criterion | Machine Room (MR) | Machine Roomless (MRL) |
|---|---|---|
| Machine location | Separate room above or beside the shaft | Inside the hoistway, at the top of the shaft |
| Building space | Requires a dedicated room (approx. 5–12 m²) | No separate room — saves floor area |
| Drive type | Geared or gearless traction | Gearless permanent magnet traction |
| Rated load | 320–2500 kg and above | 320–1600 kg (typical) |
| Rated speed | 0.5–4.0 m/s and above | 0.5–2.5 m/s (typical) |
| Energy consumption | Higher with geared machines | Lower — gearless PM motors, regenerative drive option |
| Noise and vibration | Isolated from the shaft by the machine room | Requires careful isolation design in the shaft |
| Headroom required | Standard | Slightly greater overhead in some designs |
| Maintenance access | Easy — technician works in a separate room | From the car roof or a control cabinet on the top landing |
| Installation cost | Lower equipment cost, higher construction cost | Higher equipment cost, lower construction cost |
| Best suited to | High-rise, heavy load, high duty cycle, retrofit in existing shafts | New builds, residential and commercial mid-rise, space-constrained projects |
| Standards | EN 81-20 / EN 81-50 | EN 81-20 / EN 81-50 |
