A transport cradle for a skid-supported helicopter having a pair of laterally spaced and generally parallel support skids. The cradle comprises a main frame (2, 102) comprising a pair of laterally spaced elongate support arms (4, 104) extending generally parallel to each other and a cross support (6, 106) coupling together first ends of the elongate arms (4, 104). Each support arm (4, 104) is coupled to a support wheel (12, 112) towards a second end. At least one clamp (24, 124) is coupled to each support arm (4, 104) to engage a respective helicopter skid after the cradle has been presented to a helicopter supported on the ground by its skids. A drive unit (8, 108) is coupled to the cross support (6, 106) at a pivot (10, 110) positioned between the elongate arms(4, 104), the drive unit (8, 108) including a steerable drive wheel (14, 114) and a second drive unit wheel (16, 116). The steerable wheel (14, 114) and the second drive unit wheel (16, 116) are located within the drive unit (8, 108) on either side of the pivot (10, 110). The main frame is supported by the support wheels (12, 112) and the pivot (10, 110) between the cross support (6, 106) and the drive unit (8, 108) in at least a first configuration. |
