Crane energy consumption detection device

The utility model discloses a crane energy consumption detection device, which relates to the technical field of crane energy consumption detection and comprises an equipment box and a lifting ring fixedly connected to the top surface of the equipment box. The tension sensor and the laser are adopted to measure the distance, during detection, a hoisting rope of a crane can be connected with a hoisting ring, a heavy object is hung on a hoisting hook, in the hoisting process, the tension sensor measures the gravity of the heavy object, the laser range finder measures the ground clearance, namely, the hoisting height, and the gravity and the hoisting height are sent to the monitoring host through the wireless data transmission terminal; after the hoisting rope is hoisted to a certain height, a worker can record the hoisting time, the power consumption ratio of the crane can be obtained by multiplying the weight of the heavy object with the hoisting height and the hoisting time and comparing the product with the
