A passenger cableway refers to a mechanical and electrical device that uses powered drive and flexible ropes to pull carriers such as cabins in order to transport people, including aerial passenger cableways, cable cars for passenger transport, and towed passenger cableways. The operational management, routine inspections, and major repairs of passenger cable cars are essential for ensuring their safe operation. Which of the following requirements for the safe operation of passenger cable cars is correct? ( ) A. A passenger cable car should undergo three test runs before starting to carry passengers each day. B. Single-track circular cable cars with fixed grippers generally are not allowed to operate at night. C. On single-track circular cable cars, the fixed grippers that are spaced equally along the track should be moved at regular intervals. D. Inspectors responsible for monitoring passenger cable car systems should conduct a full inspection of the entire line at least once a week
The C passenger cable car should be carefully inspected before each day of operation, and a test run with an empty car should be conducted before carrying passengers. Option A is incorrect. According to the \"Guidelines for Safety Assessment of Operational Passenger Aerial Cable Cars,\" when cable cars are in operation at night, appropriate lighting must be provided in the stations and along the tracks. The voltage of the electrical lines on the supports shall not exceed 36V, to prevent people from getting trapped at night due to insufficient lighting, which could hinder timely rescue efforts. Option B is incorrect. According to documents such as \"Emergency Response, Investigation, and Handling of Special Equipment Accidents,\" the fixed grippers on a single-track circular cable car, which are spaced at equal intervals, should be shifted at specified time intervals. Option C is correct. Line patrol workers must conduct inspections at least once a week per shift and keep proper records. Option D is incorrect.
