Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
119 words
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.
Claim 2
Dependent Claim
119 words
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.
Claim 3
Dependent Claim
24 words
A device according to claim 1, in which said first conveyor means is variable as to its angle with regard to said first platform.
Claim 4
Dependent Claim
29 words
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.
Claim 5
Dependent Claim
95 words
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.
Claim 6
Dependent Claim
77 words
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.
Claim 7
Dependent Claim
47 words
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.
Claim 8
Dependent Claim
