Automatic CBR Loading Machine , 50 Kn

STANDARDS : EN 13286-47; BS 1377:4; ASTM D1883; AASHTO T193;  NF P94-078; AS 1289.6.1.1; UNI CNR 10009

ParsRos  Automatic CBR Loading Machine frame  is composed of a robust and compact two column frame with adjustable upper crossbeam driven by

an electromechanical ram with a maximum capacity of 50 kN and data acquisition and processing system.

The Automatic CBR Loading Machine is  designed to load the penetration piston into the soil sample at a constant rate to measure the applied load and piston

penetration at predetermined intervals.

The ram speed can be set between 0.5 mm/min to 5 mm/min by using the Digital Readout Unit. This main feature allows the userto perform tests complying to

BS, EN, ASTM or AASHTO standards with the same machine.

Max movement and mound are controlled by safety switch .cylinder stroke while controlling stability measuring instrument and mound.

Rapid adjustment of the platen is also provided by up and down buttons which are located on the front panel of the digital readout unit.

Default Platen rate is 1mm/min or 1.27 mm/min also maintained under load thanks to an overpowered electric motor.

For safety, the upand down travel of the lower platen is limited the use of limit switches.

The measuring system consists of a 50 kN capacity load cell fitted to the upper cross beam to read stability values and the 25 x 0.01 mm displacement Sensor fitted

to the column.

Features of the Digital Cbr Test Machine

Graphical data  on  the  screen  is  refreshed  simultaneously during test procedure

Capable to Access and use previously done test data

Able to edit test parameters of the testing equipment through Software

Graphical outputs and reports can be saved as a MS Excel worksheet

Maximum flexibility to edit report and graph templates

TFT Graphic Display Data Acquisition and Control Unit

Communication port

Large graphic touch screen display 240 X 128 pixel,

Effective resolution 16 bit ,

Effective sampling rate 40 Hz ,

Features Of the Software

The   software continously updates load and displacement until the end of test. When the test is completed,the sharpest slope of the

graph is calculated. The point that this line crosses displacement axis is commented as an offset. This offset is subtracted from the

displacement value at peak point and called as flow.
