I run some pretty big machinery, but off the top of my head I believe this to be the biggest hyster I have run... A Hyster 1050, a 105,000 and some change capacity, the total machine weight empty if I remember correctly is 234,000 lbs..
This is a picture I took from my cab of my partner loading some poles onto a barge.
Believe it or not but its pretty damn common to tip these machines over onto their noses in my industry. Varying terrains and ramp angles with big loads that shift the load centers beyond the machines capacities..
