Compression Testing Machine

Loading Frame

The load frame is steel welded. It is designed to withstand a few million times of full cycles of loading without any sign of distortion or fatigue. These frames are light in weight. The base carries a fine finished hydraulic ram and the lower platen. The top plate has a spherical seating to take care of any irregularity of the specimen surface or slight misplacement of the specimen from the central axis. The front cover is made of an expanded sheet, which is provided as protection to the operator while at the same time giving an unobstructive view of the specimen under test. An additional frame is provided by the side of the main unit for testing of samples in flexure as per EN 196 is fixed on the left-hand side of the main loading unit

Power Pack

Powerpack is placed by the side of the loading unit and is connected to the main unit through quick-couplings. It is powered by a single-phase motor to load the unit to its maximum capacity. It has provision for fast lift and also for the selection between the compression unit or flexure unit.

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.
