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 nominal 55 blows per minute.
This compactor is suitable only for Marshall moulds diameter 4“.
The compactor is supplied complete except for the mould which must be ordered separately.
