The process of converting an existing machine-room lift to a machine room-less configuration by relocating drive components into the hoistway.
Full Definition
MRL modernisation replaces the overhead or basement machine room equipment with a compact gearless traction machine mounted in the hoistway, typically on the top guide-rail bracket or within the overhead space. The controller is relocated to a slim cabinet at the landing. Benefits include reclaiming the machine room for productive use, improving energy efficiency with gearless PM motors, and updating the lift to current safety and control standards. Engineering assessment of headroom and pit depth is essential before undertaking MRL conversion.
