Weekly inspection schedules an all heavy mining gear is a vital element of mining engineering upkeep requirements of crucial and pricey mining machinery.
The particular focus of these inspections is always on those key high stress parts and areas of the machines that have a history for stress and fatigue fractures.
Repairs and refurbishment of a stressed or cracked part are always quicker to do to complete the earlier the difficulty is noted.
Case in point:
A 390 ton Terex RH170 excavator on-site at a coal mine goes thru is usual weekly maintenance inspection and is found to have a noticeable stress fracture in the vital H-link. The machine is instantly taken off line. Every hour of down time = money lost for the mining company.
The engineering team are called out to the mine to appraise the issue and get on with the business of getting the machine back on line as swiftly as possible. The 5 man Mining Engineering Fast Response Team have the broke 2.4 ton H-link removed from the machine and a replacement fitted to the makers spec is five hours flat.
The machine is re-certified and back on line inside six hours of the team arriving on site. But that is the easy part. The Broke 2.4ton H-Link is loaded and transported back to the workshop facility where the team do a thorough inspection on the fracture and confirm the best plan to fix and refurbish the H-link.
Backed by years of expertise the mining engineering team is well capable in what must be done to fix the cast and grade steel H-link. Although this 2.4 tonne part is sizable, the team have at their disposal a considerable range of heavy lift kit and all the required tools to get the job done quickly , effectively and safely.
A well established and step-by-step process of cleaning, grinding, pre-heating and air ark gouging lays bare the breaks and prepares them for the critical cross and mix 81NI Mig welding that will not only repair the breaks but will actually reinforce what are known to be weak or potential failure areas.
Engineering a world's best practice repair on this urgent piece of equipment needs both the talent and focus of the mining engineer and the conformity to a very technical process of preheating, gouging, run off plates, grinding and layering of the 81NI Mig welds.
The final result is a completely redecorated H-link that's completely repaired, cleaned, repainted, re-certified and returned to the mining company prepared to be swapped out to another machine if the eventuality pop up.
The 24/7 engineering fast response team members pride themselves on providing mining engineering services that get high worth mining machines back on line in the shortest time possible, making sure any down time and subsequent loss of revenue to the mine is keep to a minimum.
