1. Supporting structure for a setting down dump truck, having pivot arms (7, 8) located on supports and operating cylinders (16, 17) for the operation thereof, characterized in that the supports are parts of a flat l-shaped frame (1), whereby the web of the l-frame consists of at least two longitudinal runners (2, 3) serving to support the structure on the chassis (4) of the vehicle and to take up the load, and whereby the beams of the l-frame consist of at least one rear and one front lateral runner (5, 6) connected to the longitudinal runners, in that the two pivot arms (7, 8) are mounted to a shaft (9) located in the area of the rear lateral runner (6), and in that there are provided two bars (10, 11) extending in lateral direction of the structure outside of the longitudinal runners (2, 3) and connected to the lateral runners (5, 6), whereby the section modulus of the two bars (10, 11) is considerably lower than the section moduli of the two longitudinal runners (2, 3). |
