本检控装置能使天车在运行中,让操作者正确判断天车横向位置,对准地面吊运的物件。在天车的大梁上安装5组无触点开关(图1),并在操作室安装了相对应的表示吊钩位置的指示灯。传感器是采用高频发振式无触点开关。动作原理 The prosecutor enables the crane to be in operation, allowing the operator to correctly determine the transverse position of the crane and align the objects hoisted on the ground. Install five sets of contactless switch (Figure 1) on the girder of the crane, and install the corresponding indicator light indicating the position of the hook in the operation room. The sensor is using high-frequency vibration-type contactless switch. Action principle
