<p>A self-propelled dolly for the movement of aircraft comprises a pair of laterally spaced apart first ground-engaging wheels (14) each mounted about a portion of a split first axle mounted in respective parallel members of a bifurcated chassis portion, the members defining therebetween a space to receive an aircraft wheel (36A); one or more second ground-engaging wheels (14A) mounted on a second chassis portion pivotably connected to the bifurcated chassis portion about a substantially vertical axis (23) to provide steering ability to the dolly, the second chassis portion including handle means (21) extending therefrom for control of the dolly by an operator; and a motor and drive means operatively connected to at least one of said ground-engaging wheels; the bifurcated chassis portion being formed in two sections pivotably connected together about a lateral pivot axis at an intermediate location between said first and second wheels, whereby said sections are lowerable and raisable at their mutually connected ends with respect to the ground, means to support an aircraft wheel being mounted on one of said sections and including releasable locking means to maintain said sections in the raised position, in which an aircraft with a wheel thereof supported above ground level by the dolly may be manoeuvred.</p> |
