How do I prevent probe rods from falling down hole when pulling them out of the ground?
In years past, our best advice to you for preventing a tool string from falling back downhole was to use a trusty pipe wrench to help hold the rods while tripping out. Even our hard-working engineers and field teams used the old pipe wrench method during demonstrations and shows … but not with a smile on their faces!
No More! Get rid of the pipe wrenches and use the Geoprobe® Portable Hydraulic Rod Clamp that can be attached to most 6620DT, 7720DT, 7730DT, 7822DT, and 6712DT machines.
How Does the Rod Clamp Work?
The rod clamp uses an auxiliary hydraulic location on the machine with a detent button/handle on the control panel. The two-way auxiliary allows the rod clamp to open and close while maintaining constant pressure once the button or lever is let go. The adjustable rod clamp can be used with 1.25 in. to 3.75 in. rods. The rod clamp can either be put over the top of the rods or you can unpin the front of the clamp (hinged) to put it around the rods if the top of the rods are engaged with the probe machine. The rod clamp weighs about 30 lb.
Rod Clamp Advantages
Don’t fight those pipe wrenches any longer. The Geoprobe® Portable Hydraulic Clamp makes pulling rods out just as easy as driving them in!
A must for one-man operations, deep hole work with the Macro-Core® system, and for holding inner rods for dual tube systems.
Uses an auxiliary hydraulic circuit on the machine with a detent button / handle on the control panel that maintains pressure when the button or lever is released.
Two-way auxiliary hydraulics allows powered opening and closing of the clamp.
Used with 1.25-inch up to 3.75-inch rods.
For use with the 7822DT, 7800, 7730DT, 7720DT, 6712DT, and 6620DT machines.
