Sample Ejector for 4in Molds Only

Gilson Sample Ejectors quickly and easily extrude compacted soil or asphalt specimens from 4in and 6in (101.6mm and 152.4mm) Soil-Density or Marshall molds. Adapter ring accessories allow soil samples from 2, 2.5, or 3in (51, 64, or 76mm) diameter Shelby tubes to be extruded.

A 12,000lbf (53.4kN) capacity hydraulic jack with a 5.75in (146mm) stroke is mounted in a robust three-column reaction frame constructed of plated steel. Molds are positioned vertically over the piston on a load platform that prevents the emptied mold from falling back over the jack. The frame opening is adjustable for mold lengths up to 11.75in (298mm).

Specimens longer than 5in are extracted by repositioning the Adapter Ring after maximum piston travel. The spring-loaded piston automatically returns to the start position when the release valve is opened. Adapter Rings are quickly changed with two wing nuts, and Extruder Discs are secured to the top of the piston.
