コンプライアンス概要

この概要は現在英語のみで提供しています。

適用範囲

This standard applies specifically to crawler tractors used in agricultural and forestry applications. It establishes mandatory safety requirements based on the physical performance and intended use of the machinery. It does not apply to wheeled tractors or walking tractors, which are covered under other parts of the GB 18447 series.

技術要求

This standard specifies comprehensive safety and protective measures for crawler tractors. It mandates strict limits on exhaust smoke opacity and requires reliable hydraulic system overload protection. Manufacturers must ensure hydraulic lines can withstand specific burst pressure multiples and that fuel tanks pass stringent leakage and pressure tests. For operator protection, the standard requires safety glass for cab windshields, fire-retardant interior materials, and robust guarding for exposed rotating parts and power take-off (PTO) shafts. It also sets specific criteria for braking performance on steep inclines and mandates adequate lighting, including minimum headlight luminous intensity and rear reflector visibility. Additionally, the standard outlines requirements for user information, requiring permanent product nameplates, clear safety signage at critical danger points, and comprehensive instruction manuals detailing emergency measures and operational safety protocols.

試験方法

The standard outlines several key testing procedures to verify compliance. These include exhaust smoke measurement according to GB/T 3871.13, and noise level evaluation at the operator's position as defined in GB/T 3871.8. Braking performance is rigorously tested on a 30% gradient to ensure reliable parking. Furthermore, it details specific methods for evaluating headlight beam positioning using either a standard screen method or a dedicated headlight testing instrument, as described in the normative Annex A.

よくある質問

What products are regulated under GB 18447.3-2008?

This standard specifically regulates the safety requirements for crawler tractors used in agricultural and forestry applications. It does not apply to wheeled or walking tractors, which are covered under other parts of the GB 18447 series.

Are there any updates from the previous version of GB 18447.3?

The current version revised and partially replaced GB 18447.1-2001. Key updates include changes to exhaust smoke measurement methods, the addition of fire-retardant requirements for interior cab materials, new hydraulic pressure and fuel tank testing parameters, and the introduction of specific headlight intensity and positioning rules.

How does GB 18447.3-2008 differ from ISO standards?

While the standard references certain international frameworks like ISO 12100 for basic machinery safety concepts, it establishes mandatory limits tailored specifically to the Chinese market, such as a maximum exhaust smoke opacity of 2.3m⁻¹ and specific 30% gradient braking performance tests.

The summary above provides a high-level overview of GB 18447.3-2008.
