STRATEGIES TO SIGNIFICANTLY REDUCE SCHEDULED MAINTENANCE DOWNTIME DECREASE SCHEDULED MAINTENANCE DOWNTIME EQUIPMENT DOWNTIME MANAGEMENT IS SOMETHING THAT THE AIRLINE INDUSTRY HAS LARNED AND MASTERED, THE LARGEST MINES IN THE WORLD HAVE ALSO IMPLEMENTED THESE SAME TECHNIQUES – WE ARE ATTEMPTING TO BRING THESE TECHNIQUES TO THE REST OF THE INDUSTRY. PLEASE NOTE THAT THESE TECHNIQUES ARE NOT EXPENSIVE TO IMPLEMENT, THEY ACTUALLY SAVE MONEY AND MOST HAVE RETURN OF INVESTMENTS THAT ARE MEASURED IN MONTHS RATHER THAN YEARS. TIME BETWEEN SCHEDULED MAINTENANCE CAN SIGNIFICANTLY BE INCREASED VIA THE USE OF HIGHLY ADVANCED/IMPROVED FILTERS AND LUBRICATION. WE ARE AIMING TO IMPROVE THE LIFE OF FILTERS AND LUBRICATION OIL BY A MINIMUM A FACTOR OF 5. TIME BETWEEN SCHEDULE MAINTENANCE CAN ALSO BE MINIMIZED VIA THE USE OF HIGHLY ADVANCED/IMPROVED TIRE/UNDERCARRIAGE TECHNOLOGY, VIA THE USE OF THE LATEST AND MOST ADVANCED SHOP MANAGEMENT TECHNIQUES, AND VIA THE MOST ADVANCED ROAD MANAGEMENT TECHNIQUES DEVELOPED BY WORLD RENOWN EXPERTS THAT HAVE IMPLEMENTED THESE TECHNIQUES IN THE LARGEST MINES IN THE WORLD, AUSTRALIA. UNSCHEDULED MAINTENANCE CAN BE SIGNIFICANTLY REDUCED VIA IMPROVEMENTS IN THE RELIABILITY OF THE COOLING SYSTEM (FAN, PUMP, RADIATOR, COOLANT & HOSES), THE HYDRAULIC SYSTEM (PUMPS, HYD. MOTORS & CYLINDERS), AND OTHER SUPPORTING COMPONENTS.

DECREASE SCHEDULED MAINTENANCE DOWNTIME INCREASE LIFE OF LUBRICANTS & HYDRAULIC OILS/FILTERS ULTRA HIGH PERFORMANCE SYTHETIC ENGINE AND TRANSMISSION OIL KIDNEY LOOP ULRA FILTRATION ONBOARD OIL ANALYZERS IN ORDER TO KNOWN EXACT MOMENT WHEN OIL NEEDS TO BE CHANGED ULTRA ADVANCED HYDRAULIC OIL ULTRA ADVANCED GREASE - OUR GOAL IS TO INCREASE THE LIFE OF ALL LUBRICANTS BY A FACTOR OF 5X - Lubricant life is to be extended by switching to a highly advanced synthetic lubricant that lasts many times longer than conventional lubricants. - Lubricant life is often limited by the amount of metal contamination, we solve this by the use of a kidney loop ultra filtration system that keeps oil as good as new. This ultra filtration system removes water, soot and metallic contaminants. - Lubricant life is also limited by the TBN and TAN #s, we propose the use of onboard continuous monitoring analyzers in order to know the exact moment when these levels change from acceptable to unacceptable levels.

DECREASE SCHEDULED MAINTENANCE DOWNTIME IMPROVE MAINTENANCE SHOP EQUIPMENT PORTABLE KIDNEY LOOP FILTRATION EQUIPMENT HIGHLY ADVANCED FLUID S DISPENSING AND MANAGEMENT ANALYZERS FUEL OIL LUBE OIL GREASE TANK FARM RECEPTION & FILTRATION EQUIPMENT FOR: New fuel oil, lube oil, hydraulic oil and grease contain many contaminants that create premature wear on equipment and components. These contaminants are almost never filtered as it is assumed that since these products are new they should be contaminant free. By treating these products before they get into the equipment we are insuring a decrease of unscheduled maintenance. Once equipment gets to the shop it needs to be out as fast as possible – we have access to world class fluid dispensing equipment specialized in getting the job done as fast as possible. Oil analyzers, viscosity, oil in water and water in oil analyzers are key to getting quick results and getting equipment out the door so that the equipment is mostly working and not at the shop.
