Automatic potable rock direct shear testing apparatus
Instrument reading value
This type uses a manual hydraulic pump for pressurization, and the hydraulic pump instrument reads the MPa value for normal and shear loading strength values. The kN value is selected through a calibration conversion table. Normal and shear displacement deformations are manually read using a dial gauge. It mainly consists of normal loading device, horizontal shear loading device, shear box, displacement device (optional) accessories, etc.
