Abstract
The hoist for raising railways wagons when replacing axles has two uprights joined by an overhead cross beam. The wagon is supported on L-shaped brackets which are raised by hydraulic jacks in the uprights. Each bracket has two rollers which run in adjacent guide channels within the uprights. The inner guide channels terminate some distance above ground level. This enables the bracket (16) to swing outwards about the upper roller since the lower roller is no longer in its guide channel. With the brackets retracted the wagon can be moved from its position between the uprights.
