STRUCTURE FOR A DUMP TRUCK WHOSE DUMPBOX RESTS ON A CRADLE-FRAME, THE LOWER PART OF SAID DUMPBOX FITTING INTO SAID CRADLE-FRAME

摘要

The present invention relates to a new construction method for dump vehicles. The box (6) rests on a fixed cradle (5) which acts as a frame (1) and that the lower portion of said box (6) comes to be embedded in the cradle and this because the section of the cradle corresponds to the section of the lower portion (10) of the box of smaller dimensions, to allow embedding of the box in the cradle. Said box and said cradle are constituted by volumes with practically concentric cross sections so that the lower portion (10) of said box fits exactly into said cradle. The invention applies to dump vehicles.
