    • A dozer blade control system controls the position of a bulldozer blade, maintaining the blade at a constant position as the dozer travels through a worksite. The control system monitors the angle of the dozer blade with respect to the earth and when it senses that the dozer blade is tilting, it corrects the dozer blade's position by extending or retracting hydraulic cylinders that couple the dozer blade to the chassis of the crawler-tractor. When the dozer chassis pitches forwards, the blade begins to tilt forward and to drop closer to the ground. The control system senses this forward rotation of the blade and retracts the hydraulic cylinders that couple the blade to the chassis, causing the blade to return to and maintain its original position. Conversely, when the dozer chassis pitches backwards and the blade begins to tilt backward and rise higher above the ground, the control system extends the hydraulic cylinders coupling the blade to the chassis and lowers the blade, causing the blade to return to and maintain its original position with respect to the earth.
    • 推土机叶片控制系统控制推土机叶片的位置,当推土机穿过工地时将叶片保持在恒定的位置。 控制系统监测推土机叶片相对于地球的角度,并且当其感测到推土铲叶片倾斜时,其通过将推土机叶片连接到履带的底盘上的液压缸来校正推土铲叶片的位置, 拖拉机。 当推土机底盘向前倾斜时,叶片开始向前倾斜并靠近地面。 控制系统感测到叶片的正向旋转,并将连接叶片的液压缸缩回到底盘,导致叶片返回并保持其原始位置。 相反,当推土机底盘向后倾斜并且叶片开始向后倾斜并且在地面上方升高时,控制系统将连接叶片的液压缸延伸到底盘并降低叶片,使得叶片返回并保持其原始 相对于地球的位置。
