Abstract
Abstract An arrangement for use on a vehicle, especially truck for transporting portable bridges, with the sections of a portable bridge being adapted to be arranged one above the other on support frames, and being adapted to be received on the support frames, by means of a bridge placing apparatus. The support frames are distributed over the effective length, behind the cab of the particular truck, and secured to the frame or the like thereof. The support frames are provided as independent components, releasably securable to the vehicle frame or to a loading platform, and the support frame immediately adjacent the cab is provided with a pivot drive arrangement for moving the sections of the portable bridge in the longitudinal direction of the vehicle.

Total Claims: 14
Claim 1
Independent Claim
158 words
An arrangement for use on a convertible load carrying vehicle, especially a truck independently usable also alternately when required for securely transporting portable bridges, said bridges including sections adapted to be arranged one above the other and being adapted to be respectively loaded onto and unloaded from said vehicle from and onto a bridge placing apparatus; said vehicle including a frame, and a cab mounted on the forward end of said frame; said arrangement comprising in combination therewith: a first independent support frame releasably securable near said cab on said frame of said vehicle for supporting bridge sections; a pivot drive unit operatively connectible to said first independent support frame for moving sections of said portable bridge in the longitudinal direction of said vehicle; and a second independent support frame releasably securable on said frame of said vehicle at a predetermined distance more remote from said cab than said first independent support frame for also supporting bridge sections.
Claim 2
Dependent Claim
158 words
An arrangement for use on a convertible load carrying vehicle, especially a truck independently usable also alternately when required for securely transporting portable bridges, said bridges including sections adapted to be arranged one above the other and being adapted to be respectively loaded onto and unloaded from said vehicle from and onto a bridge placing apparatus; said vehicle including a frame, and a cab mounted on the forward end of said frame; said arrangement comprising in combination therewith: a first independent support frame releasably securable near said cab on said frame of said vehicle for supporting bridge sections; a pivot drive unit operatively connectible to said first independent support frame for moving sections of said portable bridge in the longitudinal direction of said vehicle; and a second independent support frame releasably securable on said frame of said vehicle at a predetermined distance more remote from said cab than said first independent support frame for also supporting bridge sections.
Claim 3
Dependent Claim
47 words
An arrangement in combination according to claim 1, wherein said first and said second independent support frames respectively comprise: a base frame securable to said frame of said vehicle; and support members connectible to said base frame for providing support surfaces for sections of said portable bridge.
Claim 4
Dependent Claim
