It is a motor driven mechanical compactor useful for soil compaction into 100mm or 150mm dia moulds.  Two sets of rammers are provided, one of 2.6 kg, and arranged for 310mm drop and other 4.9 kg and arranged for 450 mm fall. For Compaction soil into 150 mm dia moulds, 100 mm face dia rammers having weights 2.6  kg and 4.89 kg are used. Where as for 100 mm dia moulds they are of 50mm dia. The rammer assembly is provided with  a ratchet and pawl arrangment to lift it from the top of the soil layer.  When the rammer reaches the required height the pawl release the rammer which falls freely on soil surface.  The release mechanism is operated by an arm moving up and down which is connected to a reduction gear coupled to the motor through another arm. An automatic blow counter fitted to the compactor is used to set the number of blows.


The base plate of the specimen mould is to be fitted to the rotaing base plate of the instrument which makes 1/5th revolution per stroke.  The equipment is suitable for operation 230 volts, 50 cycles, single phase, A.C. supply  Moulds are to be ordered separetely.
