Why do elevators have weight limits?
Show answer & explanation
Answer: Cable strength has maximum load
Motor overheats with heavy loads — Wrong. While motors have limits, the critical factor is cable and brake system capacity. Exceeding weight limits risks cable failure or brake malfunction.
Prevents wear on floor buttons — Wrong. Buttons aren't affected by total weight. Weight limits prevent overloading the cable and braking system beyond their safe capacity.
Cable strength has maximum load ✓ — Correct! Elevator cables are rated for specific maximum loads with large safety margins. Weight limits ensure the cables, motor, and braking system operate within safe capacity. Overloading risks cable failure, brake malfunction, or structural damage to the car.
