YJW Microcomputer Controlled Electro Hydraulic Servo Compression and Shear Testing Machine
YJW compression and shear testing machine is especially used to test the mechanical performance of elastomeric pad bearings for highway bridges. It can carry out compressive elasticity modulus test, sheear elasticity modulus test, allwable shearing angle test, ultimate compressive strenghth test, friction coefficient test, allwable rotational angle, axial compression deformation test, radial deformation test, etc.
 
The main body of the compression and shear testing machine adopts four- column structure, which is of high rigidity and able to undertake deformation tests. The microcomputer controls the automatic continuous smooth loading and load holding. It also automatically complete data collection, data storage, curve drawing, report printing, etc.
