Bogie for telescopic hangar of framed bays - uses rollers on both horizontal and vertical axles being sited with former by frame post

摘要

The bogey runs in flush embedded longitudinally slotted box section tracks, being used on e.g. horizontally telescopic framed hangars, and being fixed to the toe rails of the movable frame bays. Each bogie inc. rollers (15, 12) on both horizontal and vertical axles, the former providing vertical support and the latter restraint, with both types running on internal track faces parallel to their axles. Each bogie is sited by a frame bay end post, with roller (12) facing and in the immediate post vicinity. The retaining roller may be mounted with its axle offset in an open ended housing (10), the latter being welded to a vertical plate (7) which affixes to the rail. The two castors (15) locate on stub axles cantilevering on each side of a notched (13a) block (13) with a knife edge (7a, 13a) bearing transmitting the vertical loads from plate.
