A wheel dolly for lifting and transporting a flat tire attached to an aircraft is comprised of a frame assembly having first and second laterally spaced frame members that are pivotally coupled to each other at one side. A ram is interposed between the first and second frame members. A pair of tire lifting and support assemblies are pivotally coupled the frame assembly. A plurality of wheels is coupled to the frame assembly to allow the frame assembly to roll in any direction.

In the context of service and maintenance of heavy road vehicles, apparatus is provided that is configured to engage and support a rack and manoeuvre it into position relative to the vehicle to facilitate removal and installation of the wheels. The rack has a frame with a base and a pair of arms, each arm being pivotally attached to opposite sides of the base to pivot between an open configuration and a folded configuration. The apparatus may be expanded and contracted between an expanded configuration, where the rack engagement assembly is configured to engage the rack in the open configuration, and a contracted configuration where the rack engagement assembly is configured to engage the rack in the folded configuration.

The present invention relates to an apparatus for attaching or detaching a commercial vehicle tire hub drum. According to the present invention, the apparatus for attaching or detaching a commercial vehicle tire hub drum may comprise: a main body frame 100 having traveling wheels 110 mounted on a lower part thereof; a holding means 200 formed so as to face forward from the main body frame 100 for holding upright a circular load mounted on a commercial vehicle; an attachment/detachment means 300 for executing an attachment/detachment operation of the load from above the holding means 200; and a position adjustment device 400 coupled to the main body frame 100 to adjust the position of the holding means 200 and the attachment/detachment means 300. Accordingly, the present invention provides an apparatus for attaching or detaching a commercial vehicle tire hub drum, which, by using a hydraulic device providing a hydraulic driving force, can conveniently attach or detach a load of various sizes to a vehicle from a fixed position while simultaneously adjusting the vertical position of a load-holding means.

A towing vehicle for aircraft and method for towing an aircraft. The towing vehicle has a chassis, running gear that carries the chassis, and drive, which drives the running gear for moving the chassis. A support wheel receiving device is mounted on the chassis so that it can rotate around a vertical compensation axis of rotation, in particular within a 360 degree rotational range, relative to the chassis. A rotary drive drives the support wheel receiving device. A sensor array with alignment sensors senses alignment of the aircraft relative to the alignment sensors. The towing vehicle has a digital control unit to regulate rotational position of the support wheel receiving device as a function of the sensed alignment of the aircraft relative to the alignment sensors by the rotary drive to keep alignment of the support wheel receiving device relative to the aircraft within a prescribed range.

A rough terrain cart for a wheel chair includes a frame operable to support a wheel chair and a wheel chair user. A pair of cart drive wheels are rotationally mounted to the frame. A locking mechanism is engaged with the frame. The locking mechanism is operable to secure the wheel chair to the cart. A rotational mechanism is engaged with the frame. The rotational mechanism is configured to support a pair of wheel chair drive wheels of the wheel chair and is operable to enable the wheel chair drive wheels to rotate when the wheel chair is secured to the cart by the locking mechanism. A transmission system is engaged with the frame. The transmission system is connectable to the wheel chair drive wheels. The transmission system is operable to transmit torque from the wheel chair drive wheels to the cart drive wheels.

In one embodiment, a wheel righting apparatus includes a main frame and a wheel latching frame that is pivotally coupled to the main frame. The wheel latching frame is configured to be removably coupled to a wheel. The wheel righting apparatus also includes a winch assembly coupled to the main frame. The winch assembly is operable to move the wheel from a horizontal position to a vertical position by pivoting the wheel latching frame relative to the main frame.

A wheel detailing stand that provides for 3-point contact with a wheel mounted thereon is disclosed. The wheel detailing stand includes a base frame having a bottom frame member and a back frame member extending upwardly from the bottom frame member, a pair of bottom rollers attached to the bottom frame member where the pair of rollers are arranged in parallel and spaced apart from one another, and a back roller attached to the back frame member and oriented generally orthogonally to the pair of bottom rollers. The pair of bottom rollers and the back roller provide 3-point contact with a wheel positioned on the wheel detailing stand.
