Compression (Cube) Testing Machine Electrically – Cum-Hand Operated,
Model EM (E & H). The press frame same as for EM (H) including hydraulic ram assembly, to and bottom platens, heavy and sturdy lead screw with spherical seating, but the Hydraulic Electric-cum-hand pumping unit having the following characertstics.

Pumping Unit. The double glunger pump is a motorized unit, which is housed in an elegant cabinet, is driven by three phase, electric motor 440 volts, A.C. supply (NB : Machine can be supplied for operation 220/230 volts. 50 cycles phase A.C. supply also-as may be indicated in the order.) The pumping unit is a separate unit connected to the jack by means of a steel connecting tube. A junction box is suitabily fixed to connect the motor to the main through the push bottom starter.

The pumping unit is fitted with 20 cm dia dial pressure gauge (Hydraulic) with 200 division-in tones or in KN< (as per the rated capacity of the machine) A maximum red pointer is provided to facilitate taking reading after failure of specimens. The pressure gauge is fixed at an angle for easy readability. 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 electrical pumping unit is fixed with a micro switch to off the motor automatically as the load on the machine approaches at rated capacity. Relays are also incorporated in the pumping unit so that in case of break down of power supply the motor will stop and would not restart unless starting switch is operated.

Capacities : 10 tonnes, 25 tonnes, 50 tonnes, 100 tonnes, 200 tonnes or 100 K.N., 250 K.N., 500 K.N., 1000 K.N., 2000 K.N.
