The moving bottom of the skip 1 is constituted by the carrying run of a belt 5. Each of the two ends of this run is turned through 180 DEG by a drum 6, 7, and then again through 180 DEG still in the same direction by a roller 11, 12, in order to finally attach itself to the chassis at 14, 15. The two rollers 11, 12 are carried by a single or double carriage system 13 which nuts 16 and rotating longitudinal screws 17 displace in order to displace double quantities of the carrying run of the belt 5. The latter is supported by a table 25 possibly equipped with rollers. A flap 2 which can be raised allows the discharging of material thus transported by the belt. <IMAGE>
