Safety concerns and repairs

The system was closed for 16 months due to safety concerns and repair efforts. It was reopened in April 2010.

Ventilation problems

Ventilation in each passenger cabin has been criticized as being inadequate so that passengers should be forewarned that the cabin may become extremely hot and humid, especially in the midday sun. This has been largely mentioned when the Maokong Gondola began operating with several "halts" during service hours, trapping the mid-day heat within the cabins.

Recommendations have been made to equip cable cars with solar panels to generate power for ventilation or fans.^[2]

Service interruptions and technical problems

On the first day of operation, a faulty door lock left Mayor Hau Lung-pin and former Mayor Ma Ying-jeou suspended for 10 minutes in mid-air. Later, bad weather also caused operations to shut down a few times. Violent thunderstorms returned the next day and operation was suspended for a few hours.

At 4:50 p.m. on 21 July 2007, the service on the gondola system was suspended for approximately 2 hours due to a mechanical glitch, trapping 323 people on the cable cars. The evacuation took place from 5:50 p.m. through 6:55 p.m. TRTS personnel reimbursed passengers by giving them NT$1,058 and free tickets worth NT$100 each. The system resumed normal operations at noon the following day.^[3]

On 24 July 2007, the service on the gondola system was suspended twice. Service was suspended at noon for around two hours due to a thunderstorm, and again at 3:10 p.m. due to mechanical problems. No passengers were trapped on the gondola cars.^[4] Consumers' Foundation, Taiwan recommended that the Maokong Gondola should shut down completely, and only re-open after evaluating and repairing all systems.

Originally the Maokong Gondola was closed to public every Monday for maintenance servicing, in accordance to an agreement with Taipei City Hall. In July 2008, a full week of maintenance was also done.

On 2 October 2008 the Maokong Gondola was closed pending structural repair after mudslides left a 2.5 meter gap beneath a support pillar.^[5]

Environmental concerns

Local environmental protection groups such as Green Party Taiwan and Homemaker's Union have discouraged people from using the gondola lift. Local residents have complained about excessive noise during operation, increased garbage and the danger of mudslides.^[6]

Tests conducted by the Environmental Protection Administration under the Executive Yuan and the TCG Department of Environmental Protection have shown that noise levels are within regulations. To mitigate environmental damage, construction pillars and excavation were minimized.^[6]

On 2 November 2008, concerns were legitimized when a mudslide and earthquake eroded pillar T16, which now hung 2.5 meters above ground. The System was then closed for repairs and was reopened before April 2010 after inspectors found that the design, construction method, and engineering quality all met with requirements.^[2]

Typhoon Jangmi and erosion of pillar foundation

Rains associated with Typhoon Jangmi caused erosion around a pillar on the Corner 2 Station. As a result, on 1 October 2008 operations of the Gondola were suspended for one month to allow a full safety inspection to be carried out.^[7]

On December 1, investigators recommended the relocation of pillar T16, the foundation of which had been eroded by the rainfall of four typhoons and was very unlikely to withstand future earthquakes. Relocating T16 and neighboring pillars took two years.^[8][9] The gondola officially resumed service as of 31 March 2010, after relocation of the pillar and passing safety inspections.^[10]

These and other problems have contributed to the system's consistent financial losses.^[11]
