Laboratory Compression Testing Machine

The Compression Testing Machine consists of a steel cross head and steel base with two solid pillars connecting the base and cross head firmly tightened by nuts. The hydraulic jack of 200Tons / 2000KN capacity is fixed to the base. The upper platen has got a self aligning action and is attached to a screw which passes through cross head and can be raised or lowered for initial clearance adjustment. The lower platen rests on the jack ram and is positioned with the help of centring pin. Loading is accomplished by the upward movement of the lower platen. A dust cover is provided on the jack to protect any dust from going into the cylinder. A set of two spacers with center locating pin is provided to test small specimens.

The upper and lower platen of the machine are hardened , ground and polished . Guidelines are marked on the lower platen to keep the specimen coaxial with the hydraulic jack.The motorised pumping unit which is housed in an elegant console of double plunger type and is driven by 3 phase 440 volts 50 Hz electric motor and provided with a push button starter. The pumping unit is a separate unit connected with high pressure copper tube to the jack.

The pumping unit is fitted with three 20cm. dia.
Pressure Gauge : 0-200T, 0-100T and 0-50T or 0-2000KN, 0-1000KN and 0-500KN.,placed at an angle on the pumping unit for easy readability. A maximum red pointer is provided to take the readings after failure of specimens.
