Due to the rough, muddy and angulating terrain, a 6-wheel drive articulated dump truck; the CAT 745C was the preferred vehicle of choice to suit these requirements.
QMW utilized the load sense hydraulics on the 745C hoist circuit to provide hydraulic pressure and flow to the hydraulic motor/pump combinations. Product delivery is electric over hydraulic controlled via an IFM controller and PVG control valve. Software was developed on the IFM controller to include activation of Hydraulic Power, Flow meters, Delivery meter & reset, Product Pump On/Off function, reel retraction and levels indicators via pressure transducers, all integrated through the programable logic controller (PLC).
A remote control was integrated into the system to control the ‘’reel retraction’’ for each of the 15 hydraulic rewind hose reels which allows the service person to select which reel to retract on the IFM control screen, and actuate the remote control, walking in the chosen reel and guide with ease and efficiency. This can be done per reel whilst still pumping other products = faster servicing & re-fueling.
