MRL / MACHINE ROOM LESS GOODS LIFT , Model Name/Number: MRL / MACHINE ROOM LESS GOODS LIFT

  • (Customer Reviews)
Overview

A Machine Room-Less (MRL) Goods Lift is a modern vertical transportation solution designed to move heavy freight without the need for a dedicated structural room above or beside the lift shaft.

In a traditional traction lift, the motor and controller live in a "penthouse" room on the roof. In an MRL design, the compact motor is mounted directly inside the hoistway (the shaft), usually on the guide rails or a specialized bracket at the very top.

  • The Controller: Since there is no room for it, the control panel is usually built into the wall of the top floor landing, hidden behind a slim, locked steel door.

  • Heavy-Duty Cabin: Usually finished in "Durasteel," chequer-plate flooring, and reinforced with "bump rails" to protect the walls from trolley impacts.

  • Counterweight System: Even though it's compact, it still uses a counterweight to balance the load, which is why it stays so energy-efficient.

  • Safety Gear: Includes an overspeed governor and instantaneous or progressive safety gear that "grips" the rails if a fault occurs.

Feature MRL Traction Traditional Hydraulic
Machine Room Not Required Required (usually at bottom)
Travel Height High (Up to 30+ floors) Low (Typically 2–6 floors)
Energy Use Low (Regenerative options) High
Heat Output Low High (Oil heats up)
Maintenance Low/Moderate Moderate (Seal/Oil changes)

 

  • Space Saving: By eliminating the machine room, you gain usable floor space or reduce the building's total height. This is a massive "win" for architects and warehouse managers.

  • Energy Efficiency: MRL gearless motors use up to 30–50% less energy than hydraulic or older geared traction systems.

  • Environmental Impact: Unlike hydraulic lifts, there is no hydraulic oil involved. This removes the risk of leaks, odors, and the need for oil disposal.

  • Smooth Performance: They offer superior leveling accuracy (crucial for loading pallets/forklifts) and a much quieter, smoother ride than traditional goods lifts.
