Compression Testing Machine Electrically-cum-hand operated. The machine embodies an Hydraulic system designed to meet the requirement of Indian Standards Specification 516-1959 for compression tests on concrete Cubes upto 5cm x 5cm x 5cm 7.06cm x 7.06cm x 7.06cm, 10cm x 10cm x 10cm and 15cm x 15cm and also concrete Cylinders upto 10 x 20cm, 15 x 30 cm height

Loading Unit :- The hydraulic jack of is fixed to the base. The upper platen has got a self-aligning action and is attached to a screw, which passes thru the cross-head plate, and can be raised or lowered for initial clearance adjustment. The lower platen rests on the jackram and is positioned with the help of a centering pin. Loading is accomplished by the upward movement of the lower platen.

A dust cover is provided on the jack to prevent any dust from going into the cylinder. A spacer with a centering locating pin is provided to test small specimens. The lower and upper platens of the machine are hardended , ground and polished. Guidelines are marked on the lower platen to keep the specimen coaxial with the hydraulic jack.

Pumping Unit :- The motorised pumping unit, which is housed in an elegant console is of double plunger type and is driven by a single phase 220/440 Volts 50 cycles electric motor. The pumping unit is a separate unit connected to the jack by means of a Rubber Hose Pipe. A junction box is suitable fixed to connect the motor to the mains thru a push button starter.

Hose Pipe. A junction box is suitable fixed to connect the motor to the mains thru a push button starter. The pumping unit is fitted with a 20 cm diam dial hydraulic Pressure Gauge with 100 division i.e. calibrated against N.C.B. Tested proving ring. A max red pointer is provided to facilitate taking readings after failure of the specimen. The Machine is fitted with a hand wheel control which enables the rate of application of load to be varied. The Machine is Equipped with Facilities for Hand Pumping in Case of Power Failure.

The electric pumping unit is fixed with a micro-switch off the motor automatically as the load on the machine approaches the rated capacity Relays are incorporated in the pumping unit so that incase of break down of power supply, the motor will not re-start unless the starting switch is operated As fully described above but with One Pressure Gauge

Code : RSEP-047

IS : 516 BS 1881, ASTM C78
The machine consists of a hand frame. The lower platen has two rollers the distance between which is adjustable For 150 mm x 150 mm x 700 mm beam, the centre distance between rollers is 600 mm, while it is 400 mm for beams of size 100mm x 100mm x500mm. The upper platen has also a pair of rollers whose distance is adjustable. It is 200mm centre to centre, for 150mm x 150mm x 700mm size beam and 133 mm for 100 mm x 100 mm x 500 mm size beam. A pressure gauge to indicate load is fixed on the load frame. A small pumping unit is attached to the load frame. Total capacity of the machine is 100 KN and a 150mm dia pressure gauge 0-100 KN x 1 KN is fitted on the machine Since this is a hand operated light weight machine, its is useful for field laboratory also.
