  1. What is the maximum allowable rope slip on a traction drive sheave as defined by ASME A17.1?

    Answer: No specific rope slip percentage is mandated; traction must be sufficient to stop car under rated load

    ASME A17.1 requires adequate traction to prevent slippage under worst-case load conditions rather than prescribing a specific percentage of slip.

  2. When installing a hydraulic elevator, what is the purpose of the check valve in the hydraulic circuit?

    Answer: Prevents the car from sinking when the pump is off by blocking backflow of oil

    The check valve holds oil pressure in the cylinder, keeping the car at its landed position when the pump motor is de-energized.

  3. What is the function of the car top inspection station (CTIS) on an elevator?

    Answer: Allows authorized personnel to operate the car at low speed from the car top for maintenance

    The CTIS provides an inspection control that overrides normal operation, limiting car speed to inspection speed so technicians can safely work on top of the car.

  4. In a gearless traction elevator, what component directly drives the hoist sheave?

    Answer: Permanent magnet synchronous motor rotor

    Gearless machines use a permanent magnet synchronous (or DC) motor whose rotor is directly coupled to the drive sheave, eliminating a gearbox.

  5. What is the primary hazard associated with improperly adjusted car and counterweight clearances in the hoistway?

    Answer: Collision between car, counterweight, and hoistway walls or equipment

    Insufficient clearances risk impact between moving components and fixed hoistway structures, which can cause catastrophic failure and injury.

  6. What type of guide shoe uses a renewable liner that slides along the rail?

    Answer: Sliding (friction) guide shoe

    Sliding guide shoes use replaceable plastic or bronze liners that contact and slide along the three faces of the T-rail, providing guidance with low maintenance.

  7. What must be verified before performing the final acceptance test on a newly installed elevator?

    Answer: That all required inspections, adjustments, and safety device tests are complete and documented

    All components must be properly installed, adjusted, and tested—including safeties, buffers, governor, and interlocks—and records must be available before final acceptance.
