<p>The invention concerns a chock or wedged block for trucks and industrial vehicles. It is made from a single whole element (11) cut from steel sheeting, with longitudinal right angled bent borders (14',15', 16') folded on to itself in correspondence with two transversal parallel lines to form a wedge shaped body, welded laterally at least at the point where the areas of the right angled edges (14',15' 16') are adjacent so as to form a solid structure with a rectangular base (A), an inclined reinforced plane as a wheel rest (B) and a reaction strut (C) between the base and the wheel-rest plane. <IMAGE></p> |
