Alrighty, my first speed modeling challenge! This was interesting, I've never looked this closely at forklifts before.
I box-modeled almost everything, beveled some edges here and there, used a few bend modifiers. It was pretty straight-forward. I've never modeled a wheel like this before, so I'm not completely happy with that, but I did learn from it. And I didn't even get to the big tall pieces on the front of the forklift, so it's incomplete. I'm still happy with how much I got done in 100 minutes though- the time really flies by!
