Product name：YZW-30A microcomputer controlled rock direct share apparatus 
Product introduction

YZW-30A series microcomputer control electronic rock direct shear apparatus on the basis of the national industry standard (SL264-2001): Water Conservancy and hydropower engineering rock test procedures > (JTG, E41-2005) "provisions of the highway engineering rock test procedures > and developed, the test machine based on the existing domestic and foreign products, mining drive technology with dual AC servo motor (the first domestic), sensor technology, computer control and software technologies, the development of a new generation of rock and concrete test equipment, can be used for rock structure (such as joints, layer, film, splitting and surface position), the rock itself and concrete or mortar and rock cementation surface shear test, and concrete combined with other materials surface shear strength test. The test equipment fully listen to the engineering department and scientific research departments, to overcome the uneven traditional electro-hydraulic servo drive stability, oil leakage and high failure rate and difficult To eliminate the shortcomings, this machine has the advantages of compact structure, beautiful style, simple maintenance, convenient operation, the whole test process available microcomputer automatic control of the Win7; is a domestic initiative, and with the international advanced level.

Loaded with AC servo, the normal load is more accurate, more stable and smoother.
