The utility model discloses a weight-free elevator overload detection instrument. The weight-free elevator overload detection instrument comprises four electromagnets, four connecting chains, an electric cylinder, a pressure sensor and an electric cylinder bottom plate, the device is simple in operation, does not need to rent and transport weights, saves material resources and manpower, relatively shortens the time spent on inspection, achieves the loading test of an overload protection device during the regular inspection of an elevator, and guarantees the normal operation and safety of the elevator. Meanwhile, the reading of the pressure sensor is controlled and read, and the pressure reading is converted into the weight, so that the detection personnel can quickly judge the load weight of the elevator when the elevator weighing switch acts, and the elevator overload detection is more accurate compared with elevator overload detection by using a weight. 本实用新型公开了一种免砝码的电梯超载检测仪器，所述免砝码的电梯超载检测仪器包括有：四电磁铁、四连接链、电动缸
