Earthwork Equipment Capacities
(OP)
Does anyone know if the rated capacities of a Caterpillar 621F and D300E are theoritical, based on the actual volume of the bowl or dump or do they take into account the loose (uncompacted) nature of the material being hauled? If they are theoritical does anyone have a factor to use to approximate the uncompacted volume?





RE: Earthwork Equipment Capacities
The rated mass load is based on how much the vehicle is able ot carry without exceeding the maximum gross vehicle weight and therefore stepping outside it's rated brake safety certification.
Depending on the density of the material going into the bowl, either the volume or the mass could end up being the limiting factor to how much the scraper or truck is able to carry.
