Purpose :

Machine used for testing compressive strength of concrete cubes

Description :

This machine consist loading unit and pumping unit. 

Loading Unit: Loading unit have high stiffness welded frame or similar tested for stability. Heavy duty spherical seat in lubricating oil bath, allowing initial free

alignment at the initial contact with the specimen and automatic jamming up to

the end of test. The hydraulic jack shall be fixed to the base , the upper plate

must have aligning action & shaft attached which passes to the cross head and

can be raised and lowered for initial clearance for adjustment the lower plate

rests on the jack ram and shall be positioned with the help of centering pin. The

lower and upper plates of the machine shall be hardened, ground and polished.

Pumping Unit: The double stage hydraulic pump shall be a motorized unit

connected to a jack by means of a steel connecting tube. This should consist

Dual stage pump, centrifugal for fast approach and multi-piston for loading,

DC/ACmotor.

Automation and Computerization: This whole system fulfill following features.

1. Automatic performance of the complete test cycle with closed lube digital feedback.
2. Full computerized system with dual user interface display and PC.
3. Compatible with new intuitive easy to use data manager software.
4. Reduced power consumption and silent operation by Energy Saving Technologies.
5. Internal graphic printer including load time plot.
6. Simultaneous display of load-specific load, actual load rate and load / time graph; LAN connection to PC; advanced memory management; multi coefficient calibration. Recording facility of up to 10 test profiles for each channel including type of test (e.g. compression, flexural, indirect tensile), specimen size and shape, load rate, standard in use and other general information. Each one of the recorded test profile should be recalled automatically to save time.
7.   Hardware : Touch screen colour graphic display, sampling rate 50/sec, large storing capacity on USB pen drive, test data downloadable to PC, internet port.

8. Safety features: Includes Max. Pressure valve to avoid machine overloading; piston travel limit switch; emergency stop button; front door and rear transparent fragment guard.
