Abstract
A self-propelled helicopter ground handling dolly (10) comprises a central framework on which are mounted two casters (16) and a fixed powered drive wheel (14), a single lifting arm (22) which lifts a lifting framework (22) designed to engage lifting points on the underside of a skid-equipped helicopter (114), a handle (24) offset from the longitudinal center of the dolly (10) to enable maneuvering said dolly (10) into position under the helicopter (114), and a hand held control (102) that permits the operator to control the forward and reverse motion of the dolly (10) and the lifting motion of the lifting arm (22) from a position near the end of the tailboom (118).
