The disclosure simulates the carrying person by water distribution, which not only improves the safety in the detection process, but further facilitates operation. More prominent is that the disclosure solves the problem of counterweighting of analog bearers. Traditionally, the bearers are simulated by heavy blocks. Since the weights of heavy blocks are fixed, comprising 200 kg, 150 kg, 100 kg, 50 kg, etc., it is impossible to divide the lifts' loads finely (limited by the weight standard of heavy blocks), the operation quality can only be detected roughly based on the weight of heavy blocks. For example, three 150 kg+four 100 kg+one 50 kg=900 kg for quality detection. For weights such as 820 kg and 730 kg, the detection data can not be obtained. The disclosure solves the problem and enables free counterweighting.
