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.
