Built for Tough !
Easy to set up the rig with its versatile and flexi-boom structure. This Gemsa design boom structure, gives fast and secure drilling from vertical to horizontal ( with minimum ground clearance ) , inclined and even face drill to drill surface.
Robust mast structure can be easily accessed and maintained. Operator has excellent accessibility for minor and major maintenance work.
GEMSA DW Model Drill Head is a modular , compact design for maximum flexibility and with easy interchangeability of individual components. It can drill in both ways.
It is based on proven and tried technology with simple design, which ensures continuous and uninterrupted operation ,even in the harshest conditions.
Machine Controls
Drilling : Hydraulic -Manuel Control
Tramming : Hydraulic Pilot Control
Tramming : Radio Remote Control (Optional)
Dust Collector: PLC control
Smart Dust-Clean System
Marmorok NK200 dust collector system reduces the impact on the surrounding environment while
lowering running costs.
System cleans each filter independently and continuously
during the drilling operation. The suction capacity remains
regardless of drill rod length and rock conditions.
During drilling sequence the stopper valves are open to let air through the filters and reach the required suction. On certain intervals one valve closes and a short air pulse is introduced in
the closed filter section to clean the filter. After the clean-sing sequence both valves are open again until the next clean-sing sequence comes in action on next filter.
