Tiltable ramp for platforms (docks) for loading and unloading lorries

摘要

Tiltable ramp of the type consisting of a platform 1 with a wing 3 articulated to its front edge and which is articulated at the back to a bedplate 5 installed on the platform, which is characterized in that the means of actuation on said wing 3 are extremely simple to construct and operate and include, under the edge where it is articulated to the platform 1, a projection 22, a tooth 27 and two fins 36 forming a fork. The first rests against the platform 1 in the passive position of the wing 3, being rotated into its active position by a flexible rod 25 which links said projection 22 to the bedplate 5. Against the tooth 27 is applied a lever 28 articulated under the platform 1, which blocks and releases the active position of the wing 3, and to the fins 36 is articulated a bar 37 with a spring 41 which, suitably guided under the platform 1, damps the passage into the passive position of the wing 3.
