Machine-Room-Less Elevators | Lifts

Machine-Room-Less (MRL) Elevators are modern traction lift systems that use an electric hoisting machine located within the top of the elevator shaft to hoist the elevator car. Eliminating the penthouse machine room that is necessary for Traction Elevators, the Machine-Room-Less (MRL) Elevator is gaining popularity because they require less space, are energy efficient, and efficiently satisfy the speed and travel requirements of mid-rise buildings. Machine-Room-Less (MRL) Elevators travel at a speed of 500’ | 152 m per minute with a maximum distance of up to 250’ | 76 m. A control room is required at the highest elevator landing and must be adjacent to the elevator shaft and within 150’ | 46 m of the machine.

Common Questions
What is a Machine-Room-Less (MRL) Elevator?
Machine-Room-Less (MRL) Elevators are a modern variation of the traction lift that does not have a dedicated penthouse machine room and instead locates the machine within the override space in the top of the elevator shaft.
What are the travel and speed capabilities of a Machine-Room-Less (MRL) Elevator?
Machine-Room-Less (MRL) Elevators can travel a maximum distance of up to 250’ | 76 m at a speed of 500’ | 152 m per minute.
What are the best uses for a Machine-Room-Less (MRL) Elevator?
Machine-Room-Less (MRL) Elevators are gaining popularity because they require less space, are energy efficient, and efficiently satisfy the speed and travel requirements of mid-rise buildings.
