Wall Mount Prisms, Monopods & Accessories

Still reaching for the BACK?
If you're still hanging plumb bobs and string, surveying doesn't have to be that difficult. Wall Mount Prisms allow all surveyors to secure control points at a comfortable and accessible height while increasing accuracy and speed of use. All grade lines and azimuth are easily established using proven calculation techniques at a fraction the time reducing down time for your mining crews.

The New Era of “Tunnel Measuring”
Mechanized mining techniques have created the need of navigating underground more efficiently with reduced overhead costs. Tunnels and drifts underground have increased in size to allow for today's large mechanized machinery making it more difficult for surveyors to reach up and position their control points in the back or (ceilings). Using Wall Mount Prisms and utilizing common Coordinate Geometry techniques frees up the surveyor to place control where ever required at chest height. This simple but revolutionary idea allows surveyors the safety, speed and accuracy for marking up drifts for line, grade, tope and all other mining related surveying tasks.

The system consists of 3/8” stainless steel sleeves which are counter-sunk into the drift wall leaving nothing to be struck or bent. 
The prism adaptors are inserted into the sleeve and have a standard Leica prism mount that adapts to all Leica prisms.  The adaptor shoulder rests on the sleeve providing excellent repeatability.  The only thing left behind in the wall is the stainless steel sleeve.
Installation Procedure
* Drill a 3/8” x 4” hole in the drift wall
* Slide the Stainless Steel Sleeve onto the Setter Tool (pounder)
* Friction fit the sleeve (slightly counter sunk)
* Insert the Stainless Steel Adaptor
* Attach the Leica Prism (see Figure 1)
monopod installation
This new system is being used in dozens of mines with excellent results, offering a simple solution to wall surveying using conventional prisms.  The Leica prism offsets are known entities and listed as options within the Total Station when measuring.

What is a Monopod?

A Monopod is a mining Line and Grade tool to be used with a Laser Theodolite or Total Station. The internally threaded Bronze Wall Inserts are drilled (1 ¼”) countersunk into the drift wall, and anchored using Hilti Grout. The Monopod Wall Mount is then threaded into the Wall Insert and becomes a stable platform for a Laser Theodolite, giving miners a coordinated control station to lay out line and grade. The Laser Theodolite displays horizontal angle and percent grade directly on the working face for easy markups.
