Compression Testing Machine Electrically Operated Manufacturer,Supplier and Exporter in India
Product Code : EL-CACTE-9445
Jlab Export is a leading Compression Testing Machine Electrically Operated Manufacturer,and suppliers in India
An electric pumping unit does the work on this compression testing machine, so the operator only sets the pace with a control knob. The load shows on a 4 digit digital indicator calibrated in kN. Micro switches stop the motor as the load nears full capacity, and relays keep it from restarting on its own after a power failure.

Batch Cube Testing for Students
A common student project compares mixes with different water-cement ratios. Each batch is mixed in a Laboratory Concrete Mixer, its workability is measured with a Compaction Factor Apparatus, and cubes are cast and compacted on a Vibrating Table.
With many cubes to crush on test day, the electric pump saves the effort of hand pumping. Students watch the digital indicator climb at an even rate and adjust the knob to hold that pace. Plotting strength against water-cement ratio shows strength falling as the ratio rises.
Frequently Asked Questions
What stops the machine from being overloaded?
Micro switches switch off the motor when the load approaches the maximum capacity of the gauge. The pump cannot then drive the load past what the indicator is set for, even if the specimen has not yet failed.
What happens if the power fails during a test?
Relays in the control circuit stop the motor from starting again by itself when the power comes back. The operator has to restart it, so the ram does not move without someone at the controls.
Can the loading pace be changed during a test?
Yes. The control knob on the pumping unit sets the pace, and an experienced operator adjusts it while watching the digital indicator rise. The aim is a steady increase in load until the specimen fails.
Why does the loading pace matter?
Concrete loaded very fast shows a higher strength than the same concrete loaded slowly. Keeping the same steady pace for every cube makes results from different days and different students comparable.
