Heavy Machinery Parts
We think about repairing cars as hard or heavy work, but is worthwhile taking time out to think if the engineers and mechanics who work on heavy machinery or plant as they are sometine known. in some ways the technology is the same as our cars, in others simpler and in other harder to work on.
The technology does seem to enjoy replacement parts more than the domestic car. Take an excavator undercarriage for example (the whole rubber tracked assembly of an excavator), this can be repaired or even replaced if need be, but on a domestic car, often parts like this are just too expensive new to justify the replacement. Even small parts such as clip on rubber pads, that attach to rubber tracks. these parts are readily available and because it often costs the business more money in down time that the parts themselves, these are easily and quickly replaced , often on site.
So the relaity is that these machine are often heavier and dirtier, but can often be repaired easier than a car, because of the bolt on process of these vehicles. It would great is cars were more like this, but in reality, they could cost more and just not look as good as they do today.
