摘要

The skip (5) is made from vertical metal sheets (7) and horizontal metal sheets welded together at right angles. The vertical sheets are welded with the plane bottom metal sheet to reinforce their connection. A stiffener section (9) is welded between the interior lower end of the vertical sheet and the longitudinal edge of the bottom sheet. The upper walls of the vertical sheets are provided with a stiffener section (11) and the rear frame is provided with stiffener sections (13).
