GB/T 6067.1 Lifting Appliances Safety Regulations
ISO 12480-1 "Safety Regulations for Lifting Appliances" is a key technical specification in the crane industry. Developed by the national standards committee, this standard establishes the general safety procedures for lifting appliances.
It provides a unified technical basis for design personnel, inspection bodies, and end users. Kelude strictly adheres to the technical requirements set forth in this standard throughout its product development and manufacturing process.
Scope of Application and Positioning
ISO 12480-1 defines the safety requirements and performance indicators for lifting appliances, covering all cranes with a rated lifting capacity above 0.5 t. The standard applies not only to the design and manufacturing of new equipment but also provides clear technical guidance for the inspection, maintenance, and modification of cranes already in service. As a cornerstone of the crane standard system, it aligns with the EN 13001 Crane Safety Standard series and ISO 4309 Wire Rope Inspection Standard to form a comprehensive technical framework. The core technical parameters and safety factor requirements specified in the standard give design personnel a clear design basis and offer third-party inspection bodies quantifiable acceptance criteria for type tests and factory inspections.
Core Technical Parameter Framework
Under ISO 12480-1, the design and manufacturing of lifting appliances must satisfy a stringent set of technical parameters. These values are derived from extensive test data and sound safety engineering principles, covering everything from material selection to structural design. The safety factor ranges prescribed by the standard account for fatigue life and limit load conditions under severe operating environments. In engineering practice, design personnel must translate these requirements into concrete design parameters, ensuring that the load capacity of every component meets the mandated safety requirements.

Inspection Requirements and Intervals
GB/T 6067.1 sets out clear inspection requirements for lifting appliances under safety regulations, covering Factory Acceptance Test, Type Test, and periodic inspection. Factory Acceptance Test must be carried out on each unit by the quality inspection department at the manufacturer's facility, and equipment that passes inspection must be accompanied by a detailed inspection report and a certificate of conformity. Type Test is required when a new product enters initial production, when manufacturing is transferred to another facility, or when significant structural changes are introduced. The periodic inspection interval for in-service equipment is determined by its Work Duty classification and operating environment, generally not exceeding 12 months. For heavy-duty cranes operating continuously at A7 to A8 level, the inspection interval should be shortened to 6 months.

Safe Operation and Management Requirements
Under GB/T 6067.1, safe operation and routine management are central to crane safety. The Standard places strong emphasis on operator qualification and training, requiring that all operators complete specialized training and obtain the necessary certification before operating equipment. User units must establish a comprehensive equipment file management system that documents the full lifecycle of the equipment, including installation, use, maintenance, and inspection. Any safety hazard identified must be addressed through the rectification procedure specified in the Standard, ensuring that equipment remains safe and controllable at all times. In addition, the Standard imposes operational restrictions for extreme operating conditions.
FAQ
Q: What does GB/T 6067.1 require for the three-level inspection system?
A: Daily inspection — 15 checks per shift by the operator, 15 minutes per check; monthly inspection — safety device checks by maintenance personnel; annual inspection — full coverage by certified inspectors.
Q: What are the requirements for the Overload Limiter?
A: Trips at ≥110% of rated load, accuracy ±5%, response time ≤0.5s.
Q: What are the specifications for the Emergency Stop Button?
A: Red mushroom-head actuator with a minimum diameter of 25 mm on a yellow background. Dual-break normally closed contacts wired in series.
Q: How long must inspection records be retained?
A: Daily inspection records must be kept for at least 1 year, monthly records for at least 3 years, and annual inspection reports until the next annual inspection is completed.
