Type2 DC Surge Protective Device

利勃海尔R 9XX H2 氢气挖掘机荣获 2022 年 Bauma 气候保护类创新奖。

利勃海尔致力于开发替代驱动解决方案，采取技术中立的方法。氢内燃机是该集团正在探索的一项技术。R 9XX H2 是利勃海尔首款氢动力履带式挖掘机。该原型机由位于法国科尔马的 Liebherr-France SAS 开发。该机器由 H966 氢内燃机提供动力。它是在利勃海尔集团位于瑞士弗里堡的发动机技术中心 Liebherr Machines Bulle SA 生产的。

该公司表示，在动力、动力和响应能力方面，R 9XX H2 氢挖掘机与任何传统动力机器相比没有任何优势。它也不依赖于持续的能源供应。排放量有所不同：在“从油箱到车轮”的基础上，即在建筑工地使用时，氢挖掘机几乎不排放二氧化碳。“从摇篮到坟墓”，即从生产到退役，二氧化碳排放量比同类传统动力挖掘机低 70%。50 吨工作重量的 R 9XX H2 适合在建筑工地的极端温度、冲击和高灰尘条件下使用，可为未来的土方工程和采石应用提供强大的解决方案。

该发动机有六个气缸，采用端口燃油喷射 (PFI) 技术，利勃海尔在其氢发动机中采用了该技术以及直喷技术 (DI)。利勃海尔的零部件产品部门计划到 2025 年开始批量生产氢发动机。
