M-100 Automatic Soil Compactor w/ Molds & Hammers
Unit is designed to automatically compact soil samples rapidly and to produce the accuracy of hand compaction. For standard or modified compaction tests with 5.5 lb. hammer with 12" height of drop or 10 lb. hammer with 18" drop. Compactor accommodates 4" or 6" I.D. molds. 4" round hammer, or 6" pie-shaped hammer compensate for sample drop during compaction. The weight is concentrated at the foot, allowing free fall of the rammer. Hammer changes are made from in front of the compactor. Automatic counter registers number of blows per compaction and can be preset to stop the machine. A start-stop switch controls the operation independently from the counter control. Compaction mold is mounted on the round base; the circular base indexes automatically with each blow to ensure uniform sample compaction. A pie-shaped compactor foot is used with 6" dia. molds to completely cover the soil surface. 115V, 60Hz, 1ph AC
