<p>PURPOSE: To simply convert the direction of running, and thereby shift running to a separate running path by mounting each direction converting device onto a tuning support board where a direction converting rail is supported by a turning wheel while the crossed axes angle of a running rail is being freely turned. CONSTITUTION: When a running truck 2 of a crane, which is moved over a running rail 5, is shifted to a separate running rail 5, the running truck 2 of a crane is moved to a cross position, and respective bogie cars 2b are rested over a direction converting rail 11 of each direction converting device 10 so as to be suspended. An electrically driven cylinder acting as a turning drive means 20 of each direction converting device is driven, and a movable rod is advanced/retreated. A turning support board connected to the movable rod of a electrically driven cylinder 21 by a pin 23 is turned around over a turning wheel 16, a turning support board 12 is suspended by a stopper, and the direction converting rail 11 thereby agrees with the axial line of the intended running rail 5. Namely, the bogie car 2b to be rested over the turning support board 12 is thereby converted in direction.</p> |
