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 to rock drilling machines and pneumatic tools powered by pneumatic, electric, hydraulic, or internal combustion engines. It covers the design, manufacturing, use, and maintenance of these products, including both portable and non-portable equipment such as drill rigs, down-hole hammers, and hand-held power tools. It is essential for manufacturers of mining and construction machinery to verify if their products fall under this scope. The standard does not apply to electrically driven power tools and auxiliary equipment not explicitly listed in the scope.

技術要求

This standard specifies comprehensive safety requirements for rock drilling machines and pneumatic tools during design, manufacturing, use, and maintenance. General safety principles mandate adherence to ergonomic design to prevent operator fatigue and strict control of surface temperatures to prevent burns. Manufacturers must ensure that all accessible mechanical parts are free from sharp edges and that moving parts are equipped with appropriate protective guards. The standard also sets strict limits on noise emissions and mandates fire prevention measures, including the use of flame-retardant materials for cabins. For non-portable machinery, the requirements are more extensive, focusing on operational safety and structural integrity. Key areas include the design of control systems to prevent unexpected start-ups and ensure safe stopping, as well as the provision of Roll-Over Protective Structures (ROPS) and Falling Object Protective Structures (FOPS) where applicable. Manufacturers must guarantee machine stability under all foreseeable conditions, including transport and operation, to prevent tipping. Additionally, specific limits are placed on travel speeds, braking performance, and the layout of hydraulic and pneumatic piping to minimize hazards. Portable machines have specific requirements emphasizing operator handling and control. The design must mitigate vibration and noise at the source and ensure that exhaust gases do not harm the operator. Start/stop devices must be designed so that the tool ceases power when released, preventing accidental activation. The standard also details requirements for handles, suspension devices, and the management of dust and fumes generated during operation. Finally, the standard outlines the necessity of comprehensive usage information, including manuals, warning labels, and safety signs. Manufacturers are required to provide detailed safety instructions tailored to the specific power source of the machine, whether pneumatic, hydraulic, electric, or internal combustion.

試験方法

Verification of safety requirements is conducted through a combination of visual inspection, measurement, and specific testing procedures as defined in referenced standards. Key testing areas include noise measurement within operator cabins, which must be conducted under specified operational conditions to ensure compliance with the 85dB(A) limit. Testing also encompasses the verification of control system performance, stability, and the integrity of protective structures like ROPS and FOPS. Additionally, material flammability and the temperature of accessible surfaces are evaluated according to the methods specified in GB/T 20953 and ISO 13732-1, respectively.

よくある質問

What products are regulated under GB 17957-2021?

GB 17957-2021 applies to rock drilling machines and pneumatic tools powered by pneumatic, electric, hydraulic, or internal combustion engines. This includes both portable and non-portable equipment, such as drill rigs, down-hole hammers, and various hand-held power tools.

Are there any updates from the previous version of GB 17957-2021?

Yes, GB 17957-2021 replaces GB 17957-2005.
