ABSTRACT:
A trailer (10) constructed in conformance with European specification has three wheeled rear axles (56, 58, 60) and is adapted for the gravity unloading of a container (18) loaded with particulate lading. A container support frame (20) is pivotally connected about a horizontal axis (86) positioned between the rearmost axle (60) and intermediate axle (58) and is raised by hydraulic cylinder (92) at an unloading site as shown in FIGS. 5 and 9 for the gravity unloading of the particulate lading into a hopper (100) positioned rearwardly of the rearmost axle (60) on a rear overhanging trailer portion (72). A rotary valve (116) in the hopper feeds the particulate lading into a high velocity air stream in a lower pneumatic hopper portion (120) for pneumatic discharge.
