Patent ID: 8851546

Claim:
A load-carrying lateral extension designed to be assembled along a length a longitudinal side of at least one load-carrying platform carrying the load of a load transport vehicle, to act as a supporting surface for bearing loads or for circulation of an operator, wherein the load-carrying lateral extension comprises: a side beam ( 12 ) integral with or fixed along the longitudinal side of the at least one load-carrying platform; a rigid longitudinal junction component ( 10 ) forming an exterior limit of the load-carrying lateral extension; a multitude of individual preferably rectilinear supporting components ( 5 ) being retractable by pivoting around respective vertical axes towards each other, and connecting the side beam ( 12 ) to the rigid longitudinal junction component; each of the rectilinear supporting components is: articulated pivotally at a first extremity thereof so as to pivot on the side beam ( 12 ) around the vertical axis, the vertical axis being located on an inward side of the side beam; supported at the first extremity over a fraction of a length thereof by a load-carrying surface of the side beam; articulated pivotally at a second extremity thereof on the rigid longitudinal junction component ( 10 ); and at the second extremity thereof, each of the rectilinear supporting components engages the rigid longitudinal junction component ( 10 ), and is cantilevered laterally in relation to the at least one load-carrying platform, so as to form the supporting surface acting as a means of support and a route for passage and circulation of the operator.
