TECHNOLOGY solution. Compared to a 60m airline link between rig and compressor, direct flow because of the on-board compressor requires a much smaller compressor to get the job done. It also eliminates the need for hauling the compressor around behind a tow vehicle. This complete system now only has two engines – the excavator and the compressor – reducing fuel consumption, maintenance and repairs. The drilling machine is also fitted with two separate independent fire suppression systems supplied by Integrated Air Solutions. Suitable for any engine compartment, this triple action system from Fogmaker, Sweden, attacks all three components in the fire triangle – heat, oxygen and fuel. Using high-pressure water mist (50-micron droplets) the system can supress and extinguish engine and hydraulic compartment fires in 10 seconds with only water, and 3% AFFF and cool down the compartment to prevent re-ignition. With no powder or mess, clean-up is fast and easy, minimising downtime. After a discharge, it’s a simple matter of replacing the detector hose and refilling the piston accumulator and the system is ready to go. More add-ons The conversion of the JS205 also included the incorporation of a few additional buttons on the joystick so that all functions can be seamlessly controlled from inside the cabin, putting the operator in complete control. Another important safety feature is the inclusion of a dead man switch that puts the machine into limp mode in the event of a problem. A second JS205 drilling machine has already been manufactured and according to Roelofse a third unit will be ready in March 2018. “We keep it simple with accessible parts and quick easy and maintenance, so that the machine is the ideal workhorse for drilling applications on the African continent,” says Reolofse. Kemach Equipment has dedicated one person to site and Integrated Air Solutions has appointed a mechanic to support the Liyema Drilling team. ■ “The drilling machine is also fitted with two separate independent fire suppression systems supplied by Integrated Air Solutions.
