DragNav

The Leica DragNav option for Series 3 Dragline Monitor delivers high precision GPS guidance and positioning on draglines. It allows operators to adhere to designs, minimize re-handle and coal losses, and increase of the rate of coal uncovered.

Leica DragNav provides operators with real-time feedback on their position relative to the pit constraints and coal seams. This includes three graphical viewing screens: Pit, Dragline and Cross Sectional.

Advantages:

• Reduced need for surveyors to stake block alignments.
• Avoid the difficulties of referencing the distance and offset in bad weather.
• Achieve correct spoil placement to plan on the first pass.
• Reduce ore loss.
• Large gains in stripping volumes achieved as the digging of dirt beyond the coal strip can be prevented.
• Re-handle is minimized as operators are guided where to dig and dump in the most efficient manner.
• The pit design including key lines and surfaces can be sent directly to the dragline by radio telemetry, helping to guide operators towards higher efficiency.
• Actual dig and positioning data can be imported back into mine planning software so engineers can view the actual digging process.
• Real-time feedback for operators makes it easy to navigate to the top or bottom of the ore body.
• The operator can see the tub and boom heading in real time as well as the Fill, Dump and Drag paths.
• Row by row review of overburden blasting.
• Tub slippage alarms for the operator and office improves safety.

Other Options for Series 3 Dragline monitor:

• Leica SIMS for draglines: Allows operators to dig more and work faster whilst preserving the structural integrity of the dragline.
• Leica SIMS Plus for draglines: All of the features of Leica SIMS are included plus there are extra reporting and safety features.
