Then, the pallet 9 loaded with cargo is transferred from the rear platform 4 to the front platform 3, and is carried into the cargo compartment +1 with the longitudinal direction of the pallet 9 facing the door Ila as shown in Figure 3 (a). and install it. The unloading operation is performed in the opposite manner.

[Problem to be solved by the invention] By the way, in recent years there have been Boeing 767 class aircraft in service at airports, or Boeing 74
Since the fuselage is structurally thinner than that of a 7-class aircraft, the pallet 9 loaded with cargo should be loaded into the cargo hold with its longitudinal direction facing the longitudinal direction of the fuselage. Therefore, as shown in FIG. 3(B), it is necessary to carry in/out the cargo compartment 12 with the width direction of the pallet 9 facing the door 12a. Therefore, the width of the cargo compartment door is It is formed to 125 inches + α.

However, in the conventional aircraft cargo handling vehicle described above, the width dimension of the front platform 3 is such that the width dimension of the front platform 3 is such that the width dimension of the front platform 3 is such that the width of the front platform 3 is such that the cargo compartment of the aircraft (cargo compartment It is designed so that cargo handling services can be performed for doors with a maximum width of 96 inches + α). Therefore, in order to carry out cargo handling work on an aviation JFA (cargo door width is 125 inches + α) that has a cargo compartment configured to carry in/out with pallets 9 in the width direction, it is necessary to use the front platform and rear platform. It is necessary to make the width dimension of the pallet slightly larger than the longitudinal dimension of the pallet. Therefore, a cargo handling vehicle that is wider in overall width than the conventional cargo handling vehicle is required, but in this case, the following problems arise.

■As the overall width of the vehicle increases, driving operability and maneuverability deteriorate.

■The ground area required for public services will increase.

■There is a risk of collision with other ground service equipment within the airport.

- Due to the above problems, in order to provide cargo handling services to various aircraft, it is necessary to use two cargo handling vehicles dedicated to each aircraft, which reduces the operating efficiency of each vehicle.

The present invention has been proposed in view of the above-mentioned circumstances, and an object of the present invention is to provide an aircraft cargo handling vehicle that can perform cargo handling services for multiple types of aircraft with narrow cargo door widths.

[Means for Solving the Problems] The present invention provides an aircraft cargo handling vehicle configured to carry cargo in and out between a platform and a cargo hold of an aircraft. It is characterized by comprising an auxiliary platform rotatably provided on one side, and a driving means for raising the auxiliary platform to the same plane as the platform and lowering it from the same plane.

[Function] According to the present invention, the auxiliary platform is rotatably provided on one side of the platform in the cargo transport direction, and in the case of an aircraft with a wide cargo door, the auxiliary platform is moved flush with the platform by the driving means. For aircraft with narrow cargo hold doors, the auxiliary platform is lowered to the stowed state and the platform is used to load and unload cargo. Loading/
Carry out the removal. As a result, cargo handling operations can be performed on multiple models of aircraft with different cargo compartment door widths, improving cargo handling efficiency. Furthermore, since the auxiliary platform is stored below the side of the platform when cargo handling operations are not being performed, the overall width of the cargo handling vehicle does not increase, ensuring safety and maneuverability during driving operations.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

FIGS. 1A and 1B are a plan view and a rear view, respectively, showing the configuration of a front platform 20 of an aircraft cargo handling vehicle according to this embodiment.
