The invention discloses a wireless transmission lifting capacity indicating device for a truck with a loading crane, and belongs to the technical field of engineering machinery control. Comprising a tension sensor which is arranged at the head of a suspension arm of the truck with the loading crane and is connected with the tail end of a steel wire rope for hoisting operation; the weighing and transmitting device is arranged at the head of a suspension arm of the truck with the loading crane, and the weighing and transmitting device is electrically connected with the tension sensor; and the receiving and controlling device is arranged on an operation table of the truck with the loading crane, and the receiving and controlling device is in radio connection with the weighing and transmitting device. Through cooperation of the tension sensor, the weighing and transmitting device and the receiving and controlling device, a traditional lifting capacity indicating system is simplified, the measuring accuracy is improved to be within 3%, the cost is reduced, oil pressure, length and angle sensors are removed, the cost is saved by more than 60%, and therefore a truck with the loading crane can be easily accepted by a user, and technology popularization is convenient.

    本发明公开了随车起重运输车无线传输起重量指示装置,属于工程机械控制技术领域。包括:拉力传感器,其布置在随车起重运输车的吊臂头部并与起重作业的钢丝绳末端连接;称重及发射器,其布置在随车起重运输车的吊臂头部,称重及发射器与拉力传感器电连接;接收及控制器,其布置在随车起重运输车的操作台,接收及控制器与称重及发射器无线电连接。通过拉力传感器、称重及发射器、接收及控制器的协同配合,不仅简化了传统起重量指示系统,提高了测量精度至误差3%以内,还降低了成本,去除了油压、长度和角度传感器,成本节省超过60%,使得随车起重运输车用户易于接受,便于技术推广。
