The truck is fitted with a pantograph structure that rises to contact two overhead catenary wires, channeling external electricity directly to the wheel motors. When a trolley-capable truck enters a powered haul segment, the operator raises the pantograph; upon exiting, the pantograph is lowered and the truck reverts to diesel-electric propulsion.<\/p>\n<span class=\"cn-note\">\u67b6\u7ebf\u52a9\u529b\u662f\u4e00\u79cd\u77ff\u7528\u6280\u672f\uff0c\u7535\u9a71\u52a8\u77ff\u7528\u81ea\u5378\u5361\u8f66\u5728\u8fd0\u8f93\u5468\u671f\u4e2d\u80fd\u8017\u6700\u9ad8\u7684\u9636\u6bb5\uff08\u901a\u5e38\u662f\u91cd\u8f7d\u722c\u5761\u6bb5\uff09\u4ece\u67b6\u7a7a\u76f4\u6d41\u8f93\u7535\u7ebf\u8def\u83b7\u53d6\u7535\u529b\uff0c\u800c\u975e\u4f9d\u8d56\u8f66\u8f7d\u67f4\u6cb9\u53d1\u52a8\u673a\u3002\u5361\u8f66\u4e0a\u5b89\u88c5\u6709\u53d7\u7535\u5f13\u7ed3\u6784\uff0c\u5347\u8d77\u540e\u4e0e\u4e24\u6839\u67b6\u7a7a\u63a5\u89e6\u7f51\u7ebf\u63a5\u89e6\uff0c\u5c06\u5916\u90e8\u7535\u529b\u76f4\u63a5\u8f93\u9001\u81f3\u8f6e\u6bc2\u7535\u673a\u3002<\/span>\n\n<p>The concept dates back to the 1980s and was first deployed commercially at the Chino Mine in New Mexico in 1967 using earlier-generation systems.

Cross-sectional areas typically range from 100 mm\u00b2 to 150 mm\u00b2 for mining OCS applications.<\/p>\n<span class=\"cn-note\">\u63a5\u89e6\u7ebf\u662f\u76f4\u63a5\u4e0e\u53d7\u7535\u5f13\u78b3\u5237\u63a5\u89e6\u7684\u5bfc\u4f53\u3002\u77ff\u7528\u67b6\u7ebf\u5e94\u7528\u901a\u5e38\u91c7\u7528\u786c\u62c9\u3001\u5e26\u69fd\u5b9e\u5fc3\u94dc\u6216\u94dc\u94f6\u5408\u91d1\u7ebf\uff0c\u7b26\u5408ASTM B47\u548cEN 50149\u6807\u51c6\u3002\u94dc\u94f6\u5408\u91d1\u56e0\u5176\u9ad8\u5bfc\u7535\u7387\uff08\u226580% IACS\uff09\u4ee5\u53ca\u4f18\u4e8e\u7eaf\u94dc\u7684\u6297\u62c9\u5f3a\u5ea6\u548c\u8010\u78e8\u6027\u800c\u53d7\u5230\u9752\u7750\u3002\u622a\u9762\u79ef\u901a\u5e38\u4e3a100 mm\u00b2\u81f3150 mm\u00b2\u3002<\/span>\n\n<h3>4.2 Overhead Messenger (Catenary) Wire (\u627f\u529b\u7d22)<\/h3>\n<span class=\"h3-cn\">\u60ac\u6302\u5e76\u652f\u6491\u63a5\u89e6\u7ebf\u7684\u4e0a\u65b9\u627f\u529b\u7ebf\u7f06\u3002<\/span>\n\n<p>The messenger wire \u2014 also known as the catenary wire \u2014 is the upper support wire from which the contact wire is suspended via vertical droppers.

Komatsu has already demonstrated this capability at its Arizona Proving Grounds with the prototype EVX battery truck.

Modern trolley assist has seen major renewed interest since the mid-2010s as mining companies pursue decarbonization targets. Caterpillar completed a two-year pilot at Boliden&#8217;s Aitik copper mine in Sweden, and Komatsu \u2014 partnering with Wabtec \u2014 deployed trolley-equipped 830E-5 trucks at Copper Mountain Mine in British Columbia,
