Machine used to compact and prepare proctor specimen. Sturdy design with front door acc. CE regulations and electrically operated drive system to lift and release the compaction rammer, to automatically move it from center to outer compaction and to turn the proctor mould during compaction. The complete test procedure with number and place of compaction blows per each layer is controlled by a microprocessor system with software according to each standard. Up to two standards (EN+DIN or DIN+ASTM etc.) can be memorized by the system. The machine can be installed on every stable base. The compaction height as well as the angle of rotation of mould per drop are controlled by easy exchangeable drive and angle plates. The rod of the rammer is increasing the height of the machines to 2300 mm (10-1855) resp. 2700 mm (10-1865). Different accessories sets acc. each standard (10-1855/65E10..) comprising the special operation software, interchangeable drive and angle plates as well as rammers have to be ordered in addition. The proctor moulds as per different standards (10-1752..) are also not included and are required in addition!
