The machines comprise two S.Steel column frame with adjustable upper crossbeam. The frame has 50kN capacity and the test speed is 1.27mm/min but returning speed is 5mm/min for easy re-testing.
Cantrol designs two types of CBR testing Machines:
- Digital load readout CBR test machine
- Automatic load and penetration CBR test machine
Automatic CBR test machine equipped with 30kN loadcell and 10N resolution with LVDT sensor for measuring penetration of piston. The gear motor is controlled by software to maintain the speed of loading (1.2mm/min)
Overload software protect the machine from overloading. Software calibration of load and displacement designed to calibrate the load and displacement accurately.
After setting up the mold on machine (and staring the test), all data will be saved in real time and shown on 7” touch screen display. Machine will stop automatically at the failure point and it will be returned in zero point position.
