  1. Under ASME A17.1, what is the required frequency for performing a 'no-load safety test' on a traction elevator?

    Answer: Every 6 months

    ASME A17.1 requires a no-load safety test to be performed every 6 months to verify proper operation of the car safety device.

  2. What does ASME A17.1 specify regarding the use of a 'buffer' at the bottom of a hoistway?

    Answer: Buffers must be oil type for elevators over 200 fpm

    ASME A17.1 requires oil buffers (energy dissipation type) for elevators with rated speeds exceeding 200 fpm; spring buffers are only permitted at lower speeds.

  3. Under ASME A17.1, the 'ascending car overspeed protection' requirement was added primarily to address which hazard?

    Answer: Uncontrolled upward car movement if the brake fails

    Ascending car overspeed protection (ACOP) was introduced to stop uncontrolled upward car movement, such as when a brake fails and the counterweight drives the car upward.

  4. Under ASME A17.1, which component is required to prevent the elevator car from descending into the pit when workers are present?

    Answer: Car-on-pit-floor mechanical lock

    A car-on-pit-floor mechanical lock (pit prop or equivalent) prevents the car from descending onto pit workers during maintenance work in the pit.

  5. Under ASME A17.1, what is the minimum number of hoist ropes required for a traction elevator?

    Answer: 3 ropes

    ASME A17.1 requires a minimum of 3 hoist ropes for traction elevators to provide redundancy in the event one rope fails.

  6. The 'Category 5 test' for elevators under ASME A17.1 requires which type of load test?

    Answer: Full rated load test with safety device actuation

    A Category 5 test is a full load test that includes actuation of the safety device with the rated load in the car to verify the car safety system can stop and hold the load.

  7. According to ASME A17.1, a 'mainline disconnect switch' for an elevator must be located:

    Answer: Within the elevator machine room, within sight of the motor controller

    ASME A17.1 requires the mainline disconnect switch to be located within the machine room within sight of the motor controller so that technicians can de-energize equipment safely.
