Vehicle fittings.-The bracket devise described in the parent Specification supporting the unloading hopper b is modified to provide more clearance beneath the bracket arms, to be readily dismantled, to provide lifting tackles for raising the hopper into place, and to permit of supporting the hopper at a greater height and with greater outreach. The bracket arms q are supported towards their outer ends bv chains r hung from derrick arms s. The arms q and s are pivoted on sockets q<1>, s\ adjustable on a bar o, at each end of the wall a of the wagon, and a hook p also adjustable on the bar o secures the bracket structure o, q, s to me wall at any desired height. The derrick arms s are anchored by cables t passing over sheaves t<1> and secured to eyes t<2> adjustable on the bars o. The derrick arms carry headsheaves u<0> and lifting tackle, not shown, for raising the hopper b by means of the eyes b'. The wheels u on the hopper are set back from the front edge to increase the outreach when the wheels engage the stops q<3>. In use, the tilting of the hopper is limited by links w pivoted to the arms q, and temporarily pivoted to the hopper at w<1>, and notched segments v are also provided on the hopper for engagement in various positions with a bar q<2>. In a modification, Fig. 3, suitable for use on low wagons, the bars o are integral with the hooks p and extend upwards forming a guideway on which the bracket structure q, x, s, can be raised by a hand winch V.
