No problem Yes they lay the gravel depending on the fraction in different stockpiles. And since there is a Scale in both wheel loaders, they always know how much they have in pile and loaded on trucks . On some of the trucks you can see written the tone on the dumper bed side but about 30 ton gravel on the ones with short trailer and 40 ton for the ones with long trailer :)

A video tip from dumping site for the gravel trucks ;) kzfaq.info/get/bejne/hrh2n9mrmb_OgJ8.html
