Compliance overview
Scope and applicability
This standard specifies the basic safety requirements for the design, manufacturing, installation, operation, maintenance, scrapping, and inspection of launching machines. It is applicable to highway launching machines and railway launching machines, but it does not include the flat cars used for launching machines running on railway lines. Compliance with this standard is mandatory for manufacturers and operators of bridge construction equipment in China.
Technical requirements
The standard outlines comprehensive safety requirements across several critical areas. For metal structures, it specifies material selection criteria, welding requirements, and the use of high-strength bolt connections, referencing standards like GB/T 3811 and JGJ 81. It mandates specific welding quality levels and non-destructive testing protocols for critical load-bearing components. Manufacturers must ensure that all structural welding meets the specified quality grades and undergoes appropriate inspection. Regarding main components, the standard details safety factors and scrapping criteria for lifting appliances, steel wire ropes, drums, pulleys, brakes, and wheels. For instance, it specifies minimum safety factors for wire ropes based on the working level and defines clear deformation or wear limits that necessitate component replacement. The hydraulic system must be equipped with overload protection, and the electrical equipment must ensure reliable control performance, incorporating protections against short circuits, voltage loss, and phase failure. The standard also mandates various safety protection devices, including lifting height limiters, travel limiters, anchoring devices, and wind-resistant anti-slip mechanisms. Launching machines must be equipped with interlocking protection devices to prevent simultaneous hazardous movements. Emergency stop switches must be installed at accessible control positions. Furthermore, it sets forth requirements for operation management, personnel qualifications, and on-site safety, including minimum distances from overhead power lines.
Testing methods
The standard requires daily inspections before each shift, covering control systems, braking mechanisms, wire ropes, and safety devices. Periodic inspections must be conducted according to manufacturer specifications or actual working conditions, focusing on structural integrity, hydraulic leaks, and component wear. For newly manufactured, installed, or modified launching machines, load lifting capacity tests—including static, dynamic, and rated load tests—are mandatory before initial use, following the procedures outlined in GB/T 5905 and GB/T 26470. Additionally, a safety assessment of the usage state is required when the equipment approaches its design life, reaches a specified number of bridge installations, or after a certain number of years in service.
FAQs
What products are regulated under GB 26469-2011?
GB 26469-2011 regulates launching machines used in bridge construction, specifically covering both highway launching machines and railway launching machines. It does not cover the flat cars used for transporting these machines on railway lines.
What are the mandatory clauses in GB 26469-2011?
The standard contains numerous mandatory clauses covering metal structures, main components, hydraulic systems, electrical equipment, safety protection devices, and operational management. Compliance with these clauses is legally required for products sold and operated in the Chinese market.
When is a safety assessment of the usage state required for a launching machine?
A safety assessment is required when the launching machine approaches its design life, experiences increased failure frequency, or meets specific conditions such as reaching the design-specified number of bridge installations (e.g., 1000 holes for railway machines), completing 4 installation/disassembly transfers for railway machines, or reaching 5 years from the manufacturing date.
