located essentially in the center of the vehicle and surrounded by the passenger passage is a supply hole located. This shaft can hold auxiliary equipment for the vehicle or for use with the aircraft while it is on the ground. An elevator 60 (FIGS. 4, 5 and 6), the elevator cage, is preferably located in the supply shaft 62 (see also FIG. 12) is softer in an elevator shaft is defined by upright frame members 64, by cables.66 (Fig. 12), which run over fixed rollers 68 and their opposite Ends are attached to drums 70 driven by a motor 72 (see also FIG. 4), for example, perpendicularly moveable. The elevator cage is 5 ° from the ramp (Fig. 4) across Platform 74 accessible. The elevator shaft points to the side

a door on this platform. When the elevator cage 62 is raised to the level of the lower platform 52 (FIG. 5), takes place the transition between this platform and the elevator cage similarly through a door 76, and when the cage is raised to the level of the upper platform 56 (FIG. 6), the transition between the platform and the elevator cage 62 is through a Door 78.

The angle of inclination of the bridge can of course be increased by this a mini-space, - that the hydraulic cylinders. 84 can be used to adjust the inclination of the platform in order to bring the subsequent platform into an inclination, which corresponds approximately to the inclination of the bridge to be set.

As shown in detail in FIGS. 7, 8 and 11, each bridge 32 contains a base part Io4 and a part Io6 which can be extended with respect to the base part Io4. Anti-friction rollers Io8 and Ho are arranged between the parts Io4 and Io6 in mutually perpendicular planes in order to facilitate the telescopic movement of the parts. To move the part Io6 of the bridge in the extended position relative to the base part Io4 of the bridge, devices are provided which, in the embodiment shown, consist of springs 112 which are compressed in cylinders 114 pivotably connected to the base part Io4 at point 116. The springs 112 are compressed between the bottom of the cylinders 114 and rods 118 sliding in the cylinders 114 which are pivotally connected at point 12o to a portion 122 of the extendable part Io6 of each bridge.

Attached to the end of each section 122 at 128 (Pig. It 8 and 9) is a soft trap roller I30 which is in position in contact with the side of a plug tool when the bridge 32 is in its lowered, extended position, such as it in dashed lines in Pig. 3 and Io is shown. The arrangement is such that the springs 112 can compress or expand as a result of relative movement between the vehicle and the aircraft, while maintaining contact between the pinch rollers 130 and the aircraft, without either the bridge or the aircraft structure overload.

An examination of the interaction between boarding bridges and aircraft has shown that there is considerable vertical and lateral movements of the larger aircraft in relation to the bridge structure are to be expected, and with such relative movements the Abfangwüaze Ij5o will be easy in terms of rotate the vertical movement of the aircraft, maintaining the necessary connection between the bridge and the plug-in tool remains without generating friction against the aircraft structure or overstressing the bridge arrangement. At the same time a || relative lateral displacement between the bridge structure and the aircraft by compressing or expanding cPr springs 112 added, causing a retraction or extension of part I06 of the bridge with respect to the base part Io4 of the Bridge is effected between the layers shown in solid lines and in dashed lines in FIG. One poor alignment between the aircraft and the bridge structure is taken up by the angular displacement of the section 122 with respect to the part Ιοβ of the bridge, one of the

This There is interaction between the plug stuff and the bridge structure schematically in Pig. Io shown in which the aircraft body is indicated by dashed lines in different layers and the bridge structure in a similar manner in different layers with dashed lines Lines indicated 1st.

Each bridge structure further has side guard rails (see Fig. 8), which one on the base 1g4 of each bridge 32 have attached railing section I32 and a part 134, into which the railing section I32 is inserted telescopically. Part 134 is attached to part Ιοβ of the bridge.

The entire driving structure is self-propelled, for example, with an internal combustion engine I36 (FIG. 4). This internal combustion engine is attached in the main frame 36 and has a Drive shaft I38 and a differential I4o with wheels 22 connected to the drive, via which the vehicle can also be controlled via a linkage 142. The opposite set of Wheels 21 can also be fitted with the aid of a similar linkage 144 being controlled. Both linkages 142 and 144 can with respect to their pair of wheels are locked in straight alignment to a waggle to prevent the vehicle if it is controlled via the linkage opposite the locked linkage »

At opposite ends of the vehicle are on the Platforms 52 and 56 operator stations 146 (Fig.5 and 6) are provided adjacent to the pairs of bridges, of which the Forward and backward movement of the vehicle, control
