Geoprobe® Design Engineers unveiled the new Hydraulic Liner Extruder at this years Field Days events, and the response from Geoprobe® machine owners has been send me one! Its simple to use and can be adapted to most Geoprobe® machines with auxiliary hydraulics, such as the 6610DT. It mounts to the machines side receiver hitches in just a few minutes, says Dave Golden, Project Lead, and its perfect for pushing sluggish or stuck liners from the Macro-Core® sample tubes. A two-piece adapter converts the extruder assembly to accommodate larger diameter DT325 sample tubes. It wont get every liner every time, Dave added, but our customers will appreciate having this device in the field for all of the stuck liners it does free.
Using the Hydraulic Liner Extruder is simple. A Macro-Core®, DT22, DT325, or DT45 Sample Tube with the sluggish liner is threaded on to the front end of the extruder. As the hydraulic "push" is applied to the opposite end of the extruder, the liner is slowly pushed from inside the Sample Tube and out the end of the extruder.
