— The spacing requirements for the tow bar of the high-level tow ropeway have been changed, and the spacing requirements for the low-level tow ropeway have been added (see 4.5, 2003 edition). 4.4);

— The requirement for liquid fuels has been removed (see 4.6.1 in the 2003 edition);

— Added regulations regarding the transportation of emergency sleds (see 4.7);

— Hazard identification requirements have been added (see 4.8);

— The requirements for the limit switches of the counterweight tensioning system have been changed (see 5.6.3.5, 5.9.3 in the 2003 version);

— The configuration requirements for brakes and anti-reverse devices have been changed (see 5.8.1, 5.5 in the 2003 edition);

— The distinction between intermediate stations and terminals in the disembarkation area has been removed from the configuration of automatic parking systems (see 5.11.2 in the 2003 version);

— Added requirements regarding the slope of the drop-off area (see 5.12.3, 4.7.2 of the 2003 version);

— Added station building requirements (see 5.14);

— The requirements for support ladders and portable ladders have been changed, and the content related to rope adjustment has been removed (see 6.1, 2003 version 6.1);

— The runtime wind pressure parameter requirements have been changed (see 6.2.2.1, 2003 version 6.2.1);

— Added requirements for towing cable selection (see 6.3.1);

— The requirements for connector augmentation have been changed (see 6.3.3.2, 7.1.2 in the 2003 version);
