We disclose a carriage structure for conveying coils and the like, which structure comprises a wheel-mounted platform, a lift housing carried on the platform, a lift structure slidably mounted in the housing and engaging lift means mounted within the lift housing so that the lift structure is raised and lowered upon actuation of the lift means. The lift structure includes an upper projection shaped for closely fitted insertion into an opening in an external load support. Load bearing platen is rotatably mounted adjacent the upper surface of the projection and substantially within the confines thereof, and a turnaround mechanism for the platen is mounted within the confines of the projection and in operative engagement with the platen. In certain applications, a thrust bearing is mounted between the platen and adjacent surfaces of the projection. The platen and the projection surfaces can be shouldered to accomodate the bearing. The turnaround mechanism can b both double-acting and bidirectional for the application of maximum torque to the platen.
