Gilson Company, Inc. Relative Density, Vibrating Table, 230V/60Hz HM-315

Apparatus is used to determine relative density of granular soils which normally do not respond well to conventional Proctor moisture-density compaction tests. Maximum density is determined by placing soil in special molds and densifying using a vibrating table and surcharge. Minimum index density is determined by loose placement in the molds using special pouring funnels, scoop, or shovel, depending on size of soil particles. HM-315 Vibratory Table has a cushioned steel 30x30in (762x762mm) vibrating deck activated by electromagnetic vibrator with over 100lb (45.5kg) actuator. The table has 750lbs (341kg) load capacity and requires 800 Watts, 12 amps at 230V. Table height is 21in (533mm). Vibration rate is 3,600VPM (3,000 at 50Hz) and amplitude adjusts in accordance with ASTM requirements. The solid state circuitry allows precise amplitude control even with fluctuating voltage supplies. HM-317 and HM-318 Cylindrical Mold Sets for 0.1 and 0.5ft3 (2.83 and 14.2L) capacity have attached carrying handles and guide brackets for the Gauge Set. They come complete with detachable guide sleeve with clamp assembly, surcharge base plate with removable handle, and surcharge weight with handle. Mold included with HM-317 Set is 6in (152.4mm) ID x 6.112in (155.2mm) IH; surcharge weight plus base plate has 56.5 ±0.5lb (25.5 ±0.2kg) total weight. Larger mold with HM-318 Set is 11in (279.4mm) ID x 9.092in (230.9mm) IH with 190 ±2lb (86.2 ±0.9kg) total weight of base plate with surcharge weight. HM-319 Gauge Set fits guide brackets of either Mold Set to measure distance from top of mold to top of base plate after densification (to compute volume change). Set includes a 2in (50.8mm) Dial Indicator, with 2in (50.8mm) travel and 0.001in (0.025mm) graduations, and a special holder to fit molds. A metal 3x12x1/8in (76x305x3.2mm) calibration bar is also included. HMA-60 Accessory Pouring Funnel Set is required for loose placement of 3/8in (9.5mm) and finer soil in HM-317. Set includes two 6in (152mm) diameter x 12in (305mm) long metal cylinders, each with funnel and 6in (152mm) long delivery spout attached to one end. Spouts are 1in (25.4mm) and 1/2in (12.7mm) in diameter.
