<p>The method involves placing a strap (15) under mechanical tension around a cylindrical spillplate (12) of an orifice (10) of a tank (2), where a pivot hinge (130) and tilting bolts (140) are fixed on the strap enclosing the spillplate. The tilting bolts are uniformly distributed around a lid (100), so as to uniformly hold the lid in a closed position, where the lid is hinged to the spillplate by the pivot hinge, and is kept closed by the tiltable bolts arranged along the circumference of the lid. An independent claim is also included for a composite transport tank.</p> |
