Mechatronic Engineers’ Mechanical Compression Testing Machine designed for the determination of compressive strength of cement by testing concrete cylinders of diameter 15 cm x 30cm high (6” x 12”) and concrete cube mould of 15cm and 10cm. The machine works on the hydraulic system. Where the pressure is supplied with a hand-operated pressure pump which lifts the hydraulic ram for applying a load to the concrete cylinder or cube under test kept between the two top and bottom platens. The top platen is attached to a lead screw, which has spherical seating for self-alignment and is fitted with a hand wheel for adjustment. The applied load is indicated on the 6” Dia hydraulic gauge which is marked in 1 tone division and is fitted with a maximum red pointer, in addition, to live pointer. A release valve is provided on the hydraulic pump to release the pressure when the specimen breaks.

The entire system is supported on a stout and perfectly balanced steel structure with extra-thick steel plates both at the top and bottom. The machine is nicely painted in hammer tone spray.

Channel type Load Frame: In these load frames “C” channels are used, they are welded at the top as well as the bottom and withstand high loads. A hydraulic jack is fitted at the center of the base of the load frame, over which can be fitted lower platen and spacer block with help of centering pin. A lead screw passes through the top of the frame. To the lower end of this lead, the screw is fixed the upper platen with a spherical seat for self-alignment. The platens are accurately machined, hardened, and polished. The lower platen has concentric grooves to correctly place the specimen.
