Crandall railway dry docks are hauled by special welded-steel, open-link hauling chain pulled by the sprocket teeth of the chain wheel and returned for down-hauling by a smaller sized stud-link backing chain.

The above diagram is an example of a Crandall endless loop chain system arrangement for a typical two-chain railway. The components of this system are individually described in the links at left.
