The new generation of rock and concrete testing equipment developed by computer controlled electronic rock direct shears according to national industry standards (SL264-2001), rock test rules for water conservancy and hydropower projects , (JTG E41-2005) rock test rules for highway engineering, and by using dual-channel AC servo motor driving technology (first in China), sensor technology, computer controlled and software-processing technology. Can be used for direct shear tests of rock structures (such as joints, layers, inside, inside, crack surfaces, etc.), rock and concrete or mortar and other rubber joints and shear strength test of material bonding surface.
