With the development of railway science and technology, in order to ensure the running safety of trains, each railway bureau is provided with a train unbalance loading instrument, and through running tests for a period of time, the unbalance loading of the T11 series long-rail train set is more than 10 tons under the condition that the safety train is full of load, so that the requirements of railway technical regulations are not met. In order to solve the problem of the unbalance loading of the safety vehicle of the T11 series long rail vehicle group, the safety vehicle can solve the unbalance loading problem under the full load condition and the no-load condition by carefully investigating and analyzing and calculating a large amount of mechanics and strength. Although the fixed counterweight can solve the unbalance loading problem under the full-load state, under the empty vehicle state, the unbalance loading problem of the safety vehicle also exists when the empty vehicle is transported due to the overlarge counterweight amount. The existing scheme is installed on the vehicle iron plate, and for operating personnel dial the rail with instrument manpower such as crow bar, balancing weight is too big, and personnel's operation wastes time and energy, has the operation risk. The device is arranged on the iron floor, occupies the walking space of personnel and has potential safety hazard.
