Область применения
This standard specifies the fundamental safety requirements for the design, manufacture, installation, testing, operation, and management of passenger aerial ropeways. It is strictly applicable to reversible and circulating passenger aerial ropeways. This standard is mandatory for all manufacturers and operators of passenger ropeways in China. It explicitly excludes freight ropeways, surface lifts, ground cable cars, non-public passenger ropeways, and mine shaft commuter ropeways.
Технические требования
The standard comprehensively mandates safety parameters across multiple engineering disciplines. It defines strict criteria for line layout, including maximum inclination angles, span lengths, and lateral clearances between carriers and obstacles under specific wind loads. Engineers must strictly adhere to the specified maximum operating speeds and minimum time intervals between carriers. Regarding mechanical systems, the standard specifies requirements for steel wire ropes, including selection principles, tensile safety coefficients, and bending ratios. It details the structural integrity needed for station machinery such as driving devices, tensioning systems, and detaching/attaching mechanisms. For carrier vehicles, it outlines load calculations, grip anti-slip force requirements, and structural strength for cabins, chairs, and bogies. The standard also sets comprehensive guidelines for electrical equipment, including control systems, safety circuits, and lightning protection. Comprehensive installation tolerances and commissioning procedures (no-load and load test runs) are also mandated to ensure operational safety.
Методы испытаний
The standard outlines several critical testing and commissioning procedures to verify safety compliance. It requires non-destructive testing (NDT) for critical load-bearing components like grip jaws, drive shafts, and wheel shafts, conforming to NB/T 47013 Level I. Engineers must conduct rigorous no-load and load test runs, including half-load, eccentric load, and full-load conditions. Additionally, it mandates functional testing of safety devices, braking systems, and detaching/attaching mechanisms to ensure reliable performance under all specified operating conditions.
Частые вопросы
What types of ropeways are regulated under GB 12352-2018?
GB 12352-2018 applies to reversible and circulating passenger aerial ropeways. It does not apply to freight ropeways, surface lifts, ground cable cars, non-public passenger ropeways, or mine shaft commuter ropeways.
Are there any major updates from the previous version of GB 12352?
The 2018 version includes several significant updates, such as revised allowable swing angles for carriers, updated minimum wind pressure calculations, new requirements for chairlift minimum ground clearance, and modified friction coefficients for grip calculations. Engineers transitioning from the 2007 version must review these updated parameters carefully.
How does GB 12352-2018 relate to international or ISO standards?
The standard references several national standards for structural and equipment design, such as GB 50009 for building structural loads and GB/T 9075 for ropeway steel wire rope inspection and discard. While it shares similar safety philosophies with international standards like EN 12930, it contains specific Chinese national parameters for wind loads, rescue operations, and clearance distances.
