Key design considerations for mitigating noise and vibration in Machine Room-Less (MRL) elevator installations revolve around isolating the vibration sources and dampening sound transmission. Since the motor and drive components are located directly within the hoistway, often above the elevator car, noise and vibration can easily transmit through the building structure if not properly addressed. Firstly, vibration isolation is crucial. This involves using resilient mounts and vibration isolators between the elevator machine, its supporting structure, and the hoistway walls. These isolators are typicall....
