在装载机产品开发、设计和性能验证阶段,都要对装载机的地面位置收斗角、运输位置收斗角、高位卸料角及最高位置收斗角(简称角度参数)进行测量,以验证是否达到设计要求。以往,测量卸料角及最高位置收斗角,都是测量人员必须借助工具离开地面才能测量。其缺点是:测量 At the stage of product development, design and performance verification of loaders, we have to measure the angle of the ground position of the loader, the hopper angle of the transport position, the upper discharge angle and the angle of the highest position (angle parameter) to verify Whether to meet the design requirements. In the past, measuring discharge angle and the highest position of the bucket angle, the surveyor must use tools to leave the ground to measure. The disadvantage is: measurement
