An overhead traveling vehicle and an overhead traveling vehicle fault processing system are provided. The overhead traveling vehicle includes: an overhead traveling vehicle main body; a main walking part, installed on the overhead traveling vehicle main body and configured to drive the overhead traveling vehicle main body to walk on tracks; an auxiliary walking part, installed on the overhead traveling vehicle main body and configured to drive the overhead traveling vehicle main body to walk on the tracks; and a control part, configured to control one of the main walking part and the auxiliary walking part to be on the tracks and to control the other one of the main walking part and the auxiliary walking part to leave the tracks.

A walking device with a self-adaptive track gauge and wheel pressure for preventing rail gnawing comprises a first rail, a second rail parallel to the first rail, a driving trolley disposed on the first rail, a driven trolley disposed on the second rail, two beams connected between the driving trolley and the driven trolley and each of which having a sliding groove, and an electric hoist disposed on the two beams. The driving trolley is hung on the first rail through a first bearing wheel, and the driven trolley is hung on the second rail through a second bearing wheel. The driving trolley is connected with a driving motor, and the driving trolley is configured to drive the driven trolley to synchronously move along length directions of the first rail and the second rail through the two beams, so that the electric hoist is driven to synchronously move.

A hoist and crane assembly is presented. The hoist and crane assembly contains an extendable and retractable hoist and crane subassembly that longitudinally moves in and out from the hoist and crane assembly. Further, the hoist and crane subassembly also contains a lateral rail system for moving shipping containers side to side within an associated trailer, for example. Yet further, means for moving shipping containers from the rear to the front of an associated trailer are also contained within the hoist and crane assembly.
