Compliance overview
Scope and applicability
This standard applies specifically to walking tractors (also known as two-wheel tractors) used in agricultural applications. All technical content within this standard is mandatory for manufacturers and serves as the basis for safety inspections. It addresses the physical and performance limitations to mitigate hazards during the intended use of the machinery, referencing GB/T 15706.1-2007 for basic machinery safety concepts.
Technical requirements
The standard outlines comprehensive safety requirements across several critical categories. Firstly, it mandates protective guards for exposed rotating components, such as starting jaws, flywheels, and belt pulleys, ensuring they are securely fixed and free of sharp edges. Manufacturers must ensure proper thermal insulation for exhaust systems and specific structural integrity for fuel tanks to prevent leakage. Secondly, the standard sets exhaust smoke limits and noise limits to protect both the operator and the environment, aligning with referenced standards like GB 6376. Thirdly, it specifies braking performance criteria, requiring reliable parking brake functionality on specified inclines. Lastly, the standard dictates requirements for lighting and signaling devices, including minimum luminous intensity for headlights, and mandates clear safety operation symbols on control mechanisms.
Testing methods
Compliance verification involves several key testing procedures. Exhaust smoke measurement is conducted according to the methods specified in GB/T 3871.13. Noise level testing at the operator's position and environmental surroundings is performed as per GB/T 6229. Furthermore, braking performance tests are executed on dry, hard slopes to verify the parking brake's reliability, and lighting intensity is measured to ensure adequate visibility.
