5. Installation Considerations 安装注意事项
Successful trolley assist implementation requires careful planning across infrastructure, electrical systems, and truck modifications. Mine haul roads should be straightened where possible to reduce installation complexity. The overhead catenary system requires DC substations that convert grid AC power to the appropriate DC voltage levels for trolley operation.
成功实施电车辅助系统需要在基础设施、电气系统和卡车改装方面进行周密规划。矿山运输道路应尽可能取直以降低安装复杂性。架空接触网系统需要直流变电站将电网交流电转换为适当的直流电压。

|---|---|
| Road Alignment 道路线形 | Straight or gentle curves preferred 优选直线或缓曲线 |
| Grade Application 坡度应用 | Optimal: 6–10% uphill grades 最佳：6-10%上坡 |
