Problems solved by technology
In this way, the shear resistance performance of the rubber bearing is tested. The existing problem of this hydraulic compression shear testing machine is that the connection structure between the vertical loading cylinder and the loading plate is not easy to disassemble, and it is not particularly convenient to use. When used with two vertical loading cylinders, it is even more inconvenient when some loading cylinders need to be separated from the loading plate
