Re: What size bottle jack for bus?
an entire 72 passenger bus weighs about 20K pounds. so a 10 ton jack should be more than sufficient, since you're only lifting a quarter or half of the weight of the bus at any given time.
make sure to get one with a long stroke. My bus was stuck in the sand and i had a bottle jack that only lifted about 4 or 5 inches. That wasn't enough to accomplish anything useful.
