| 摘要 | Apron transloading device for air freight with a platform which is adjustable as to height and which comprises conveyor means while a bridge with further conveyor means is pivotally connected to said platform. Also pivotally connected to said platform is a tiltable platform which is adjustable selectively so as to form a continuation of the conveyor means on said first mentioned platform or a continuation of an additional conveyor means provided on said bridge. | ||||||
| 权利要求 | 1. An apron transloading device for air freight transloading installations which includes: a first platform, first conveyor means supported by said first platform, adjusting means operatively connected to said first platform for adjusting the latter as to height, bridge means linked to one end portion of said first platform so as to be pivotable about a substantially horizontal axis, second conveyor means supported by said bridge means, a second platform pivotally connected to said first platform for pivoting about an axis substantially parallel to said substantially horizontal axis about which said bridge means is pivotable, said second platform being adjustable selectively so as to form a continuation of said first conveyor means or a continuation of said second conveyor means. 2. A device according to claim 1, in which said first conveyor means is variable as to its angle with regard to said first platform. 3. A device according to claim 1, in which the pivot axes about which said first and second platform and said bridge means are pivotable form extensions of each other. 4. A device according to claim 1, which includes: third conveyor means arranged at that end of said bridge means which is located remote from said first platform, and a third platform tiltable about a horizontal axis and arranged adjacent that end of said bridge means which is remote from said first platform, and fourth conveyor means provided on said third platform and pivotable selectively into a first position so as to form a continuation of said second conveyor means or into a second position so as to form a continuation of said third conveyor means. 5. A device according to claim 4, which includes inductive proximity initiators respectively arranged on marginal areas of said pivotal second platform and of said pivotal third platform on one hand and on the respective adjacent marginal areas of said first conveyor means and of said second conveyor means and of said third conveyor means on the other hand for adjusting the second and third platform so as to form a continuation of the respective adjacent conveyor means. 6. A device according to claim 1, which includes guiding means extending transverse to said bridge means and adjacent that end thereof which is remote from said first platform, and carriage means arranged at said last mentioned end of said bridge means and movable on said guiding means. 7. A device according to claim 6, which includes driving means associated with said carriage means, and freely movable supporting means movably supporting said first platform. 8. A device according to claim 6, which includes a frame work extending upwardly from said carriage means and adjustably supporting that end of said bridge means which is remote from said first platform for adjustment as to height. 9. A device according to claim 1, in which said bridge means comprises at least two sections telescopically movable relative to each other and respectively equipped with interengaging fingers, each of said fingers comprising roller means forming part of said second conveyor means. 10. A device according to claim 1, in which said first conveyor means includes central roller means and lateral roller means arranged on opposite sides of said central roller means, the direction of rotation of said lateral roller means being at a right angle to the axis of rotation of said central roller means, and lifting and lowering means associated with at least one of said central roller means for selectively lifting and lowering at least one of said central roller means. |
