HM-530 Mechanical Soil Compactor automatically counts the number of hammer blows and shuts off when a preset number is reached. The sample mold indexes to a new position with each count to assure uniform compaction.
The Compactor can be used with the 4in (102mm) ID molds, 5.5lb (2.5kg) weight with 12in (305mm) drop. The HM-530 also accomodates the 6in (152mm) ID molds using either the standard 5.5lb (2.5kg) weight with 12in (305mm) drop or the modified 10lb (4.5kg) weight with 18in (457mm) drop. The standard 2in (51mm) hammer can be replaced by one of the same 3.14in2 area, but with pie-shaped face to cover entire sample surface with 6in molds. The hammer lift compensates hammer drop for soil thickness in the mold during compaction. The free-fall hammer has weight concentrated at the foot and adjusts easily from 5.5-10lb by addition of a surcharge weight.
HM-530 Compactor includes a 2in (51mm) round, 5.5lb (2.5kg) hammer, a pie-faced hammer for use with 6in molds, and a surcharge weight to increase total hammer weight to 10lbs (4.5kg). 4in (102mm) and 6in (152mm) standard compaction molds, and a digital automatic counter with start/stop switching are also included. Overall Dimensions: 12.5x29.5x56in (318x749x1,422mm), WxDxH.
