加藤汽车起重机上装有LC-2-A型或LC-1.3-A型起升荷重电子检测器,它是起重机力矩限制器的一个组成部分。现以LC-2-A型为例,说明其检修调试方法。1 工作原理LC-2A型电子荷重检测器结构见图1,电路原理见图2。检测器的工作原理:由起重机臂杆上的三点式检测机构将起重钢丝绳的张力传给荷重检测器的测力轴4,粘贴在测力轴上的R_A、R_B、 Kato truck crane is equipped with LC-2-A or LC-1.3-A lifting load electronic detector, which is an integral part of the crane torque limiter. Now LC-2-A type, for example, explain its maintenance debugging method. 1 Working Principle LC-2A electronic load detector structure shown in Figure 1, the circuit shown in Figure 2. The working principle of the detector: the crane’s rod on the three-point detection mechanism will lift the rope tension transmitted to the load detector of the force-measuring axis 4, stuck in the measuring axis R_A, R_B,
