apparently crown thinks this is a trade secret?
there is no public information available on the aisle spec's for any of thier trucks... DOH!

but if you measure the total length of the truck with forks tucked in and add 2ft your truck should operate sufficently in that width of asile.
Most reach trucks will turn within the inside front load wheel and almost turn on a dime inside the inside loadwheel given on which way your turning.

I'm assuming in the neighborhood of 8ft to 10ft asile width range.
