Why is it that big semi trucks last for hundreds of thousands of miles, but some cars start breaking at just about 100,000?
I myself work in the mining industry in australia. Recently was at a site near coober pedy in the middle of nowhere. Maintenance is a big part of it.
The Short Answer
I myself work in the mining industry in australia. Recently was at a site near coober pedy in the middle of nowhere. Maintenance is a big part of it. The road trains we had are tri-drive kenworth 908s or something but would do 6 trips a day so close to 600kms a day from site to rail siding and back a few times but every time they pulled into the yard they were checked over. Fluids, belts, tires, filters and signs of new or increasing damage/wear. One thing I noticed was different was service intervals. Regular light vehicle gets serviced ever 5000kms or 10000kms the trucks all get serviced based on hours worked like 250hrs they get fluid samples taken, 500hrs tires rotated and belts inspected or changed, 1000hrs hrs they have the oils and filters changed etc etc so each time certain hours roll around its due for something. A fair bit would come down to driver abilities/abuse I would imagibe aswell
