Machine-roomless elevators are designed so the drive machinery is integrated into the hoistway rather than requiring a conventional separate machine room. This can influence architectural planning and space allocation.
Where MRL systems can be useful
Developers often consider MRL systems when they want to reduce dedicated machine-room requirements. The actual space benefit depends on the selected equipment and the building layout.
Important design questions
Before selecting an MRL system, review shaft dimensions, pit and overhead requirements, capacity, speed, number of stops, power supply, door configuration, maintenance access and the building structure.
Get a project-specific specification
MRL is a lift configuration rather than a complete project specification. The final equipment should be selected from the building requirements and a technical quotation.
Frequently asked questions
Does an MRL elevator need a machine room?
The defining feature of an MRL system is that the main drive machinery is arranged within the hoistway rather than a conventional separate machine room. Exact equipment arrangements vary.
Is an MRL lift suitable for every building?
No single lift configuration is suitable for every project. Shaft, pit, overhead, capacity, traffic and building requirements should be assessed before selection.
