Introduction

Machine-room-less (MRL elevator) designs eliminate dedicated machine rooms but impose tighter shaft, pit, and overhead constraints than conventional layouts.

Shaft, Pit, and Overhead

Never assume passenger shaft rules from outdated non-MRL datasheets. Request current GA drawings for each load/speed class from your supplier.

Rail Loads and Maintenance Access

Provide structural engineers with rail reaction forces. Discuss maintenance platform requirements — some jurisdictions impose additional MRL rules.

Conclusion

Engage RITECH early for MONADRIVE-compatible RTE platforms and verify pit/overhead before concrete pours.
