标准解读
GB/T 44258-2024 是一项针对土方机械中高原隧道用纯电动轮胎式装载机的国家标准。该标准详细规定了此类装载机的技术要求、试验方法、检验规则以及标志、包装、运输和贮存要求，旨在确保设备在高海拔、复杂隧道环境下的安全、可靠与高效运作。具体要点包括：
-
适用范围：明确了本标准适用于工作海拔高度达到或超过2000米，专用于高原隧道施工的纯电动轮胎式装载机。这类装载机以电池为动力源，设计需考虑高海拔环境下氧气稀薄对电气系统性能的影响。
-
技术要求：
- 电动系统：规定了电动机、电池组及管理系统的技术指标，如续航能力、充电效率、电池温控系统等，确保在低温、低气压条件下仍能稳定输出动力。
- 轮胎与底盘：考虑到高原地形的特殊性，对轮胎的耐磨性、抓地力及底盘的稳定性、通过性提出了更高要求。
- 环保与安全：强调了设备在运行过程中的低噪音、零排放特性，并对操作安全、紧急制动系统、防翻滚保护等方面做出规定。
-
试验方法：详细说明了如何进行各项性能测试，包括但不限于电动系统的耐久性试验、高原环境适应性试验、装载能力验证等，确保产品符合设计要求。
-
检验规则：制定了产品出厂前的检验流程与标准，包括型式试验、出厂检验等内容，确保每台设备在交付前都经过严格的质量控制。
-
标志、包装、运输和贮存：规范了装载机的标识信息、包装方式以及在运输和贮存过程中的注意事项，以防在高海拔运输过程中因外界条件影响设备性能。
该标准的实施，为高原隧道施工中纯电动轮胎式装载机的设计制造提供了统一规范，有助于提升设备的整体性能和安全性，促进新能源土方机械在高海拔地区的应用与发展。
