COMPRESSION TESTING MACHINE

The machine is designed for portability, operating convenience and accuracy. It is a compact and self contained. Unit ideally suited for mobile and field laboratories.

Specimens upto 15cms cubes and 15 cms dia x 30 cms high cylinders can be accommodated. Load measurement is done by a 15 cms dial bourdon tube type hydraulic pressure gauge calibrated in 100 divisions, fitted with a maximum pointer (lagless pointer). The gauge is calibrated against an RTC tested proving ring. The machine is of four pillar  construction, giving excellent lateral rigidity. The hydraulic loading unit is located on the base of the loading machine. The hydraulic jack is precision machined. The piston and cylinder are ground and lapped to fine tolerances. The lower platen can be centrally located on the base, and has concentric grooves for centering the specimen. Spacer is provided to test small specimens. The upper platen is mounted on a swivel arrangement for self aligning action. The pump is fitted integral on the testing machine along with oil reservoir. The hand operated pump is of two speed 

concentric piston type. The  load frame  is  of  four  column construction with a fixed upper head holding the ball seated platen. The testing of concrete cubes  upto 15cm.

Load gauge is calibrated in kilonewtons  and  is  fitted  with  a maximum load pointer.

Load capacity – 100 / 150 / 200 Tons

Machine & gauge are calibrated, correct to ±1%,the range from 10% to 100% of maxm. load
