We use a steel bridger across the pits at work, 10mm plate with strengtheners they rest in about 2 or 3 inch either side, we happily work all day with the 30ton coaches sat on them. If you not certain on the edges of the pit then why not cut edges further out so you've got more area to sit something on, at most it's only goin to have 2 ton spread across 4 point of contact anyway
