Automatic Mechanical Compactor
- Humboldt - H-4169
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" (305mm) height of drop or 10 lb. hammer with 18" (457mm) drop.
Compactor accommodates 4" (102mm) or 6" (152mm) I.D. molds. 4" (102mm) round hammer, or 6" (152mm) pie-shaped hammer compensate for sample drop during compaction. The weight is concentrated ot the foot, allowing free fall of the rammer. Hammer changes are made from in front of the compactor.
Automatic counter registrers number of blows per compaction and can be preset to stop the machine. A start-stop switch controls the operation independatly 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" (152mm) dia. molds to completely cover the soil surface.
- Includes 5.5 lb (2.5 kg), 10 lb. (4.5 kg) circular-faced and pie-shaped hammers and 4" (102mm) and 6" (152mm) molds.
- Overall dimensions: 56"Hx16-1/2"Wx30"D (1422x419x762mm).
- Max height in operation: 66" (1677mm). Meets ASTM D558, D559, D560, D698, D1557, D1558; AASHTO T99, T134, T135, T180.
