Marshall Automatic Compactor
Marshall Automatic Compactor, 220v-50hz-1ph Standard ASTM : D1559 / AASHTO : T 245

This ruggedly constructed machine has been designed to eliminate the laborious process of hand compaction. It automatically compacts the specimen and stops off the motor after the preset number of strokes has been completed on the automatic digital display counter. The trip mechanism is structured so that the hammer falls at the same height at every stroke. The unit incorporates a compaction wooden pedestal. The drive mechanism lifts the 4,53 Kg compaction hammer, plated against corrosion, to the height of 457 mm. and allows free fall at 60 blows per minute
