The manual pressure equipment is used for maintaining the constant lateral pressure in the Hoek triaxial cells and consists of: a hydroponic hand pump with oil reservoir (TGE-3800), a precision LPI digital readout unit (TC-4920LP), a pressure transducer (TGM-0200) and a 1.5m long flexible hose with quick release coupling.
Any capacity which depends on the rigidity and sizes of the rock specimens to be tested, EN or ASTM automatic compression testing machines can be used for appliying the vertical loads required for the triaxial and uniaxial tests. As an option for weaker rock specimens, the compression machines can be upgraded with option UTC-0210 special calibration procedure to have Class 1 starting from 1% of the full range of the capacity
