An excavator, or any large piece of heavy equipment, is a major capital asset for any business and the objective is to extract as many hours of economic life from this asset. One way to do this is to extend the working lifecycle of the excavator as far out to the future as makes financial sense. But it is not only the lifespan that you want to optimize. You also want to optimize the efficiency and reliability of the machine – you do not want it to be sitting idle for long periods of time.
Here are seven tips to extend the life of your excavator from the Canadian Mining Journal (https://www.canadianminingjournal.com/features/seven-ways-to-extend-the-life-of-your-excavator/) Tip 1: Maintain a clean cab
The cab and windows should always be clean in order to maximize job site safety and productivity. Operators need good visibility, and with a lot of wind and fine particles, it’s easy for those windows to be caked with dirt and dust.
Use an approved cleaning solution to wash windows. Not all windows are made with the same materials – even on similar models from the same manufacturer. Check each individual machine’s manual to be sure you are using a solution that’s compatible with your windows.
Once clean, make sure all windows are in place and intact – not gouged, cracked or seriously scratched. This type of damage can compromise a window’s integrity and increase its likelihood of breaking or shattering.
Clear the cab of any unnecessary clutter and materials. Get rid of loose spare parts or trash that could affect your ability to control the machine. You also never want items to get caught behind the seat, under pedals, or in any other location that can impede machine control.
Tip 2: Take care of the tracks
To start, clean out the tracks daily. Muddy, rocky terrain can be extremely abrasive and will collect around the tracks, track shoes, undercarriage, and swing bearing. Clean-out is important because – if left in there – the accumulated mud hardens and accelerates the wear on the undercarriage and tracks and can cause roller damage.
You should also complete weekly checks of the tracks’ tension. Look for too much sag, which could damage the tracks or the rollers. See your operator’s manual for the correct track sag specifications and procedure.
Tip 3: Fix damages immediately
Once you realize your excavator is damaged, take action immediately. The longer you go without addressing it, the more wear and tear affects the machine – even on other components that aren’t broken. Repairing damages immediately helps mitigate additional maintenance costs you could otherwise incur. Contact your authorized equipment dealer to discuss a complete machine inspection and repairs.
Tip 4: Pay attention to alerts
Your excavator’s telematics is an important tool you should utilize to increase the lifespan of your machine. If you ignore alerts, you’re missing one of the key advantages of telematics.
Once you receive an alert, act on it. Merely reading the alert negates the purpose of having that valuable data at your fingertips. Contact your authorized dealer to discuss support options for telematics. Another critical alert is conducted through fluid sampling. Fluid sampling is essential to maximize uptime, limit downtime, and keep operating costs low.
Tip 5: Refuel your machine
After your shift, refuel the machine. The air in the system or the tank can result in synthetic moisture, which will water down the fuel. When refueling, top-off your DEF tank with clean, filtered diesel exhaust fluid (if equipped). On excavators, the DEF tank is typically wider and shallower than on other machines. If you don’t top it off, it can swash around in the tank creating foam and clogging the system, which can generate diagnostic trouble codes and machine downtime. In colder temperatures, keep water out of the fuel filter, so it does not freeze.
Tip 6: Inspect screen guards
On equipment where present, inspect screen guards over the windows and cab openings. Be sure they’re secure and in good condition. With such a wide range of materials such as sharp rocks and large pieces of debris, it’s important to keep those in top condition.
Tip 7: Inspect fire extinguishers and water tanks
Be sure fire extinguishers and water tanks are operable and easily accessible. Check the water pressure of the tanks. You want to ensure your safety and the well-being of your coworkers.
