★ Unique modular design, including the sample support seat, lifting device, the protection of falling hammer device, power system, control unit.
★ The transmission part adopts a full set of imported all-digital AC servo system. The force value detection part adopts the piecewise linear correction method to ensure the high precision and high stability of the machine.
★ Adopt multiple force sensor bridge structure, improve the deviation resistance of large size pipe
★ The innovation pull-type diameter measurement system, the sample is easy to install, more direct measurement, can accurately measure the pipe diameter changes.
★ The shear test frame is installed in combination with the host, which is easy to install the basement compaction device, and the shearing force is applied to the socket of the well through the flexible steel strip to adapt to the cutting test of various specifications.
★ With overload, over current, overvoltage and over-temperature protection, with mechanical, electrical, software and other security features to ensure safe and reliable operation.
★ Modular structure, to meet the user needs to expand the function of the instrument
