Disclosed is a carriage of a dump truck, comprising a box body and a longitudinal center sill (7), wherein the box body is arranged on the longitudinal center sill (7), two ends of the box body are inclined end walls (1), and the end wall (1) comprises an upper end wall (11), a lower end wall (12) and a transition wall (13); the upper end wall (11) is located at the upper side of the longitudinal center sill (7), the lower end wall (12) is located at the lower side of the longitudinal center sill (7), the slope of the lower end wall (12) is greater than or equal to that of the upper end wall (11), the transition wall (13) is connected to the upper end wall (11) and the lower end wall (12), and the slope of a line connecting the upper and lower ends of the transition wall (13) is greater than that of the upper end wall (11). In a terminal unloading region, when goods pass the transition wall (13), the frictional resistance generated by the transition wall (13) is smaller than that generated by the upper end wall (11), so that the goods can obtain an additional downward acceleration which facilitates the goods to pass; and after passing the transition wall (13), the frictional resistance generated by the lower end wall (12) is less than or equal to that generated by the upper end wall (11) so that the acceleration facilitates smooth unloading of the goods. As compared with the prior art, the terminal unloading region has a better unloading effect.
