I'm right with you there Tombie.
In my last 12mths of working in coal mines , especially draglines , we were forced to use platform ladders. Instead of one 7'/8' ladder we actually needed 3 different size platforms which had to be carried on our vehicle.
At first it was a pain in the arse but once we got used to using the platforms it was so much better and safer to work off, especially inside the draglines where there is so much machinery in close proximity.
As you would know the biggest pain was carrying the gear you needed to the area or equipment you were working on , because the park up could be 100mtrs away. And in a wash plant , how many flights of stairs one had to climb.
But the extra safety afforded by platforms far outweighed the effort needed to carry them to the job.
