Elevator Mechanic Test 2025 – 400 Free Practice Questions to Pass the Exam

The correct answer is based on the operational standards and safety regulations in the elevator industry. When a brake system slips, it can lead to an uncontrolled descent of the elevator car. The threshold for this dangerous situation typically occurs at a level where the load exceeds the designated safe capacity of the elevator.

At 125% of the rated load, the risk of the braking system failing due to excessive strain increases significantly. Elevators are designed to handle their rated loads, and exceeding this by 25% can compromise the mechanical integrity of the system, leading to scenarios where brakes may slip or fail. This is why a slipping brake at this load level is particularly concerning and why it is crucial that operational protocols prevent elevators from operating beyond their specified capacities.

The other load levels are either within safe operational limits or do not represent the same level of critical risk associated with brake slippage. At 100% and 75%, the elevator operates within its designed parameters, while 150% significantly exceeds capacity, leading to potential catastrophic failure rather than a scenario focused solely on the brake slipping.
