This is a picture of one of the haul trucks at a mine I visted in Canada - it carries 220 tons of material. They will have 26 of these on site for just of their 8 jobs sites . It was delivered with 2 semis one in front and one in the back.
Albian sands (Royal Shell) that owns it has 80 of the 350 ton trucks on the north side of there site and 60 on the south side. Albian is one of about 20 sites that are actively mining oil and is considered one of the smallest. It takes one hour to go around the site in a pick up. This site has 50 years left at the current rate. It takes 3-5 bucket loads from the shovel to fill it.
As I have said before, we invaded the wrong country!
