Patent ID: 8177472

Claim:
A process to invert a structure having a longitudinal axis, a first end, a second end, a topside and an underside, the process enabling mounting of mobility means on the underside of the structure when the structure is in a form of a vehicle body, the process comprising: attaching a rocker to the first end of the structure when the topside of the structure is facing a ground, the rocker contacting the ground; attaching a sling driven by a hoist to the second end of the structure; and rotating the structure about an instantaneous axis of rotation extending perpendicular to the longitudinal axis and being located on the rocker, by lifting the second end of the structure with the sling driven by the hoist, wherein the rocker comprises: a fastener that permits attachment of the rocker to the first end; a nib that, when the rocker is attached to the first side, extends under the topside and contacts the ground; a bar that, when the rocker is attached to the first end, extends perpendicular to the longitudinal axis; and a convex profile that extends from the nib to the bar.
