摘要

Perfected extensible box of a multiple truck for self-truck; of the type of those presenting the sides of the boxed above; characterized because the extreme posterior part of the box, defined by the corresponding zones of the sides, floor and gate, are related between and also are solidaries to the zone of the displacable chassis of the box, producing the displacement of extension of the box by means of a central hydraulic cylinder, supporting the displaced part on two faced vertical hydraulic supports; under the articulation of the porton, a tray with extreme wheels is also displaced with the moving part of the box, in whose movement the wheels of the tray discuss for a guides that presents the chassis of the truck for that effect. Whose guides remove in arched extreme zones, whose curvature cooperative in the slotting of the tray in vertical position and downwarding favoring this positioning two springs that act elastically on and related to the tray that avoid the turning of the tray in such vertical position; while the rear defense of the truck is moving outward through a hydraulic cylinder the same space that the case has been displaced.
