There is also provided a lock- ing combination on the frame and on the chassis capable of holding the frame (7) relea- sably locked to the chassis (3) when the said frame has reached the high position aforesaid. The bogie also in- cludes a horizontal fifth- wheel support (133) mounted on the frame for pivotal movement about a vertical axis whereby to allow it to sway laterally, one of the fifth-wheels (9) being mounted at the other end of the support. The bogie further includes an assembly (153, 155) for automatically centering the first wheel on the frame when the latter reaches its high position.
