GB/T 6067.1-2010 "Safety Regulations for Lifting Appliances – Part 1: General Principles" is the foundational general standard in crane safety, establishing systematic safety requirements for the design, manufacture, installation, use and inspection of all crane types. As the governing document for crane safety standards, this standard sets the framework for the entire series. This article provides a detailed interpretation of its core provisions.

Scope and Application of the Standard

GB/T 6067.1-2010 is a comprehensive revision of GB/T 6067-1985 and serves as the cornerstone of crane safety standards in China. The standard applies to all types of lifting appliances, including overhead and gantry cranes, Tower Cranes, Mobile Cranes, Jib Cranes / Boom Cranes, and cable cranes. Built on the principle of "intrinsic safety," the standard establishes a complete framework for crane safety requirements: design safety (strength, stiffness, stability calculation, and Safety factor selection), manufacturing safety (materials, Welding, Heat treatment, and inspection), installation safety (foundations, Crane Rail, and Commissioning), operational safety (Operating procedures, safety devices, and personnel qualifications), maintenance safety (Periodic Inspection, Maintenance, and repair), and inspection safety (Type Test, Factory Acceptance Test, and in-service inspection). Together with GB/T 28761 (basic requirements for safety regulations), this standard forms the two pillars of crane safety standardization.

Core Safety Requirements

The core safety requirements of the standard include: structural safety of the metal structure — Safety factor for load-bearing structures (Yield Strength n≥1.48, Tensile Strength n≥2.5), Fatigue Strength verification methods (according to working class and stress cycle counts), and discard criteria for structural components (main girder deflection exceeding L/700 requires the crane to be taken out of service). Mechanism safety — Hoisting mechanism must be equipped with a normally closed brake (automatic braking upon power failure), with a braking Safety factor ≥1.5 for Hoisting / Lifting and ≥1.25 for travel motions. Wire Rope Safety factor of 4–6 (according to working class), with at least 3 safety wraps retained on the Drum. Hooks — Forged Hook or Laminated Hook, with the Hook Latch in good working condition. Crane wheel and Crane Rail — proper wheel-to-rail matching, with Rail gnawing (wheel flange rubbing) corrected through alignment.

Safety Protection Device Requirements

The standard mandates the following safety protection devices on cranes: Overload protection device — overhead and gantry crane with Rated Lifting Capacity ≥100t and Tower Crane with a capacity of ≥200t·m must be equipped with a Safety Monitoring and Management System (per GB/T 16562), and cranes of A6 class and above must be fitted with a Lifting Capacity Limiter / Load Limiter. Limit switches — the Hoisting mechanism must be equipped with an upper Travel Limit Switch with dual redundancy (counterweight-type and rotary-type), and both the Crane Bridge and Trolley travel ends must be fitted with Travel Limit Switch and Buffer. Interlock protection — Cabin / Operator Cab door interlock (main Power Supply disconnects when the door is opened), Electrical Cabinet door interlock, and Maintenance platform door interlock. Emergency Stop — both the Cabin / Operator Cab and Floor operation positions must be equipped with a red mushroom-head Emergency Stop Button that locks when pressed and requires manual reset. Wind Protection Device / Rail Clamp — outdoor Gantry Crane and Tower Crane must be fitted with a Rail clamp and Anchor device.

Usage Management and Inspection

The standard sets clear requirements for the user unit's crane safety management: user units must establish a safety management system and maintain a safety technical file for each crane. Operators must hold valid certification for special equipment operation (Certified Operation). User units must develop Operating procedures and strictly implement them. Periodic inspection interval for in-service cranes: every 2 years (A1 to A4 class), annually (A5 to A7 class), and every 6 months (A8 class). Cranes must be taken out of service immediately for inspection after a malfunction, an accident, or exposure to severe wind or earthquake. It is strictly prohibited to modify the crane structure, remove or alter safety devices, or operate beyond the Rated Lifting Capacity without authorization. All Kelude products are designed, manufactured, and inspected in full compliance with GB/T 6067.1, ensuring that every crane leaving the factory meets mandatory national safety requirements.
