It sounds like you might be referring to MRL lifts, which stands for Machine Room-Less lifts (also known as Machine Room-Less Elevators). These are a type of elevator system that doesn't require a traditional machine room above or below the shaft. Instead, the elevator's drive system (such as the motor and controller) is integrated into the hoistway or the shaft itself.
