Automatic Marshall Compactor

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.

This compactor is suitable only for Marshall moulds diameter 4“.
The compactor is supplied complete except for the mould which must

be ordered separately.
It cannot be sold in CE markets without safety guards.
