The invention relates to the field of elevator safety detection, and discloses an elevator speed governor lifting force testing device. The elevator speed governor lifting force testing device comprises a testing table, a lifting mechanism, a clamp, a tension sensor and a control system. The lifting mechanism comprises a drive assembly, a lead screw and a movable platform. The lead screw is arranged in the vertical direction, one end of the lead screw is connected with the output end of the drive assembly, the other end of the lead screw is connected with the top of the testing table, and themovable platform is connected with the lead screw through a lead screw nut. The clamp is mounted on the movable platform through the tension sensor, a speed governor is mounted at the top end of the testing table, one end of a steel wire rope of the speed governor is connected with the clamp, and a counter weight is hung at the other end of the steel wire rope of the speed governor. The inventionfurther discloses an elevator speed governor lifting force testing method. The elevator speed governor lifting force testing device and method have the beneficial effects that the structure is reasonable, the operation is convenient, the test is started through one key of a computer, the test result is directly read, and the testing accuracy and efficiency are effectively improved.
