ABSTRACT:
Subframes (30, 70) are supported for pivotal movement under the action of hydraulic cylinders (36, 76) to selectively engage drive rollers (42, 82) with wheels (14,16) of an aerial weapons handling trailer (10). Drive motors (48, 88) are operatively connected to the drive rollers (42, 82) to propel the aerial weapons handling trailer (10) and are further adapted to lock the drive rollers (42, 82) against rotation. The drive motors (48, 88) are mounted on housings (46, 86) supported for pivotal movement about the axes of the drive rollers (42, 82). Hydraulic cylinders (58, 98) are utilized to selectively pivot the housings (46, 86) when the drive rollers (42, 82) are engaged with the wheels (14, 16) and locked against rotation, thereby rotating the wheels (14, 16) to position the aerial weapons handling trailer (10).
