This standard specifies the quality grades (qualified product and first-grade product), test methods, and inspection rules for electric rock loading machines. Quality grades are determined based on product standards, technical level, finished product inspection, production process quality checks, and user evaluation. The standard details numerical requirements for finished product inspection items (e.g., overall performance, component performance, reliability and life) and inspection items for main parts manufacturing quality (e.g., gear precision, explosion-proof performance). Test methods include measurements of bucket volume, technical productivity, noise, etc., referencing multiple related standards. This standard replaces JB/T 53514-94, with adjustments to some quality requirements and test methods.
本标准规定了电动装岩机产品的质量等级（合格品和一等品）、试验方法和检验规则。质量等级依据产品标准、技术水平、成品检验、生产过程质量检查和用户评价确定。标准详细列出了成品检验项目（如整机性能、部件性能、可靠性与寿命等）的数值要求，以及主要零件加工制造质量检验项目（如齿轮精度、隔爆性能等）。试验方法包括铲斗容积、技术生产率、噪声等测试，并引用多项相关标准。该标准替代了JB/T 53514-94，调整了部分质量要求和试验方法。
