description The elevator safety gear wedge block performance testing machine is characterized in that the elevator safety gear wedge block performance testing machine comprises a rack (1), a motor (2), a transmission mechanism, a counterweight mechanism, a testing rotating disc (3), a testing lever assembly, a weight assembly, a buffer support assembly, a turning assembly, a releasing mechanism and a material pushing sensor; the buffering support assembly is located on the testing lever assembly, the releasing mechanism is located below the testing lever assembly, the material pushing sensor is located on the edge of a safety tongs wedge block to be tested, and the releasing mechanism is connected with the testing lever assembly. The turning assembly is installed on the rack, and a turning tool bit makes contact with the outer side wall of the testing rotary disc (3) after moving. The testing machine simulates the most real elevator use condition, the braking surface of the safety tongs wedge block and the side wall of t
