A dolly for placement beneath a landing gear of an aircraft that enables transport of the aircraft without rolling the tire of the aircraft. The dolly includes a platform for a tire to rest on and a channel for positioning the tire. The dolly includes a winch for translating the dolly and aircraft tire relative to each other such that the landing gear is brought to rest on the platform, and one or more stops for securing the aircraft landing gear with respect to the dolly. Once positioned, the dolly can be used while transporting the aircraft, either by hand pushing, a hand towbar, a motorized tug with a towbar, or other mode. The dolly is useful for moving aircraft with a damaged landing gear or flat tires.

A nut pickup and fastening device for automatic tire mounting includes a nut setting unit that arranges a plurality of nuts to align with the bolt arrangement of the wheel disk of a vehicle body, and a pickup fastener coupled to the tip of a robot arm. The pickup fastener may include a tool frame unit, a plurality of nut runners provided on the tool frame unit corresponding to the set nuts and configured to provide torque for nut fastening, and a plurality of holding sockets coupled to the tip of each nut runner, configured to pick up and hold the nuts from the nut setting unit.
