A torque box chassis frame for firefighting vehicles or the like constituting a platform for extendible aerial ladders. The vehicle torque box chassis frame includes elongated lower and upper members significantly spaced from each other having rigid bracing structure interposed therebetween resulting in a rigid elongated box of significant rectangular cross section dimension. The torque box chassis frame rear end is defined by a rigid ladder turntable support including its own vertical rigid columns, and spaced outrigger support tubes for receiving hydraulic outrigger jacks are integrally defined on the torque box chassis frame to provide firm support of the torque box upon the ground eliminating the influence of the vehicle suspension system.
Cette invention concerne une poutre-caisson conçue pour un véhicule incendie ou véhicule assimilé et constituant la plate-forme d'une échelle aérienne télescopique. La poutre-caisson se compose de deux membrures allongées, inférieure et supérieure, considérablement espacées l'une de l'autre et ayant entre elles une ossature rigide qui en fait un caisson allongé rigide de section rectangulaire de dimensions appréciables. L'extrémité arrière de la poutre-caisson est définie par un support rigide de plaque-tournante d'échelle comportant ses propres montants raidisseurs. Des tubes support de stabilisateurs espacés dans lesquels se logent des vérins de stabilisation sont montés sur la poutre-caisson pour le supportage ferme de celui-ci au sol après de relevage complet de la suspension du véhicule.
