A machine room-less elevator is a traction system using special materials and improved electric motors that require little space, eliminating the need for the machine room. Which option matches this description?

• A. Express Elevator
• B. Service Elevator
• C. Hydraulic Elevator
• D. Machine Room-Less Elevator

Answer: (D)

A machine room-less setup is a traction elevator designed to operate without a separate machine room, using compact, often gearless drives and optimized components that fit into the hoistway or a small space above it. The description points to a traction system that relies on space-saving drives and advanced motors, eliminating the need for a dedicated machine room. That combination—tra­tion system plus small, efficient drive hardware—precisely matches the machine room-less concept. Other types describe different configurations or uses (for example, hydraulic systems move the car with a piston and don’t use ropes or a hoisting machine, and service or express elevators refer to the car’s function or speed rather than its machine-room requirements).
