Motorized Compression/Tension Machine Manufacturer,Supplier and Exporter in India
Product Code : EL-CL-8846
Jlab Export is a leading Motorized Compression/Tension Machine Manufacturer,and suppliers in India
This motorised frame runs both compression and tension tests. It applies up to 2000 kN in compression, for crushing concrete cubes and cylinders, and up to 500 kN in tension, for pulling steel bars. The operator controls the loading rate by hand, with a pacer to follow.

Running a Test at a Steady Rate
The load or tensile rate is regulated by hand. The pacer shows the rate the test should follow, and the operator adjusts the control so the load rises in step with it. A steady rate matters, because concrete loaded too fast gives a higher reading than its real strength.
Strength Testing Practicals in the Concrete Lab
Students cast cubes in Cube Moulds and cylinders in a Cylindrical Mould from the same mix and compact them on a Vibrating Table. The specimens are cured and crushed at set ages. Comparing the two shapes from one batch shows that a cylinder fails at a lower stress than a cube. Batches made at two or three water-cement ratios show how strength falls as water is added.
In tension, students pull lengths of steel reinforcing bar to failure and note the yield and maximum loads. Dividing each load by the bar area gives the yield and tensile strength, which they compare with the specified grade of the bar.
Frequently Asked Questions
What can this machine test?
It crushes concrete cubes, cylinders and other compression specimens up to 2000 kN. It also pulls steel bars and other tension specimens up to 500 kN, on the same motorised frame.
How fine are the load readings?
Compression loads read in 0.1 kN divisions and tension loads in 0.01 kN divisions. The finer tension divisions suit the smaller loads seen when bars are pulled.
How much room is there for specimens and fixtures?
The columns are 280 mm apart and the piston stroke is 100 mm. The span sets the widest platen or grip set that fits between the columns, and the stroke limits how far the piston travels in one test.
What is the remote button switch for?
It operates the readout units from a separate button, so the operator can stand clear of the specimen while it is loaded to failure.
How does it differ from the Digital Compression Testing Machine?
That machine is a compression frame with an electric and hand pumping unit. This one also runs tension tests up to 500 kN. It reads the load through a load cell and a two-channel digital indicator, and its loading rate is paced by hand.
