  • Patent number: 4658924
    Abstract: An aircraft ground-handling vehicle has a rear turntable carried by a platform (37) which can be tilted to present a sloping surface to a nose-wheel of an aircraft. The platform (37) is positioned within the wheel base of the vehicle. A lifting arm (39) is extendable beyond the platform (37) to engage the nose-wheel axle and is raised by lifting rams (43) to raise the nose-wheel clear of the ground. The rear vehicle chassis supporting the platform (37) is then extended beneath the nose-wheel which is lowered onto the platform. The nose-wheel is then clamped, and the lifting arm (39) and the chassis (33) are retracted and the platform (37) returned to the horizontal. The aircraft can then be manoeuvred to its desired position. The vehicle does not cause damage to the ground surface or aircraft nose-wheel or tire and is not required to have a substantial weight as is the case with hitherto known such vehicles.
