Yes- it almost certainly will be covered. Most (if not all) homeowners policies provide coverage for driveways, walkways, etc. See your policy for specific language.

As long as there is sufficient evidence that the crane caused the damage (rather than normal wear and tear) it will almost certainly be covered. Your homeowners insurance will then subrogate against the tree removal company.
