Cover of the box for loading and transporting materials, especially loose, highly dusty materials

Abstract

The subject of the application is a box cover (1) for loading materials, especially bulk materials with high dustiness, having rolled-up rollers with a sheet of protective material attached to the side of the box (1). The cover is characterized in that a roller (2.1, 2.2, 2.3, 2.4) with a sheet of protective material (3.3, 3.4) is attached to each side of the box (1), which, at the part attached to the roller, has a width similar to the width of the roller (2.1, 2.2, 2.3, 2.4). The sheet of protective material (3.3, 3.4) decreases in width towards its end not attached to the roller. On the side edges of the sheet of covering material (3.3, 3.4) there are strips of elastic material (4.3, 4.4), to the side edges of which hooks, preferably locks (5.3, 5.4), are attached, and at the end not attached to the roller (2.1, 2.2, 2.3, 2.4) there are fastening elements. Preferably, the fastening elements to the material feeder are hooks (6.3, 6.4).Hooks are attached to the inside of the box sides, which are compatible with the fastening elements. The roller (2.1, 2.2, 2.3, 2.4) has a self-winding mechanism or a manual winding mechanism.
