Patent Abstract
An operator cab for an operator of heavy equipment, the cab including a first opening and a second opening through which an operator can enter or exit the cab. The cab is mounted on the heavy equipment next to an implement for performing work. The first opening and the second opening of the cab are not generally parallel to each other. The cab is operable to rotate to a first position with respect to the deck of the heavy equipment, such that the operator can exit through the first opening and onto the deck. The cab is also operable to rotate to a second position with respect to the deck of the heavy equipment, such that the operator can exit through the second opening and onto the deck. The multiple openings in the cab assist the operator in safe ingress and egress to and from the deck and cab.
