第三节手拉杠杆操纵系统不经常动作部位的控制用手拉杠杆来操纵。如行走拐弯、铲臂的升降、行走和回转的更换等。图3为三个手拉杠杆传动示意图。它们的共同特点是操纵手柄处有限位板(10、16、17),长期放置不改变位置。操纵拉杆都有螺纹,可调节其长短,接触部分都类似一般离合器结构的卡环和滑块。手柄1、拉杆2、拉臂3、扁担4是控制 The third section of the lever control system is not often part of the control action pull lever to manipulate. Such as walking cornering, shovel arm lift, walking and slewing changes. Figure 3 for the three hand-lever lever diagram. Their common feature is that there is a limit plate (10,16,17) at the joystick for long-term placement without changing position.
