自动怠速
当停止所有操作装置动作4秒后，发动机自动转换为怠速运转，再次操作，发动机立即恢复至原先转速。采用自动怠速，可有效节省燃油。夜间在市区内作业，也不会干扰周围环境。
无尾回转，动臂侧移
动臂侧移、无尾回转，两大功能同时拥有， 助您应对复杂环境，无障碍施工。
三泵液压系统
●H·M·S液压系统，动臂、斗杆、回转采用各自独立的3泵系统，配置了控制范围更广的控制阀、变量泵。实现了快速顺畅而又强力的作业。
●配备直行前进回路，行走时，即使操作动臂也不会出现S形，速度也不会改变，因而可实现稳定的直线行驶。
●可实现四联动，通过3泵液压系统，可实现铲斗、动臂、斗杆、回转的同时操作。向翻斗车的装载作业等也快捷、顺畅。
