Bulk material transporting/storing skip, has lateral walls terminated with bottom wall near connection zone by stiffening section, where walls are made of distinct sheet metal and concavity of lateral walls directs loads along bottom wall

摘要

The skip has two lateral walls (2), a bottom wall (3) and an end wall, where the walls (2, 3) are made of distinct sheet metals. The walls (2) are terminated with the wall (3) near a connection zone by a longitudinal hollow stiffening section (4) when lateral edges of the wall (3) are connected to longitudinal edges (5) of the section. The concavity of the walls (2) directs loads in a direction of a longitudinal axis of the wall (3).
