PURPOSE:To permit stabilized good hooking and traveling actions of heavy panels by a method in which left and right-handed vertical wheels are placed on vehicular bottom walls facing each other, and while directed by projection of guide, the bearing of receiving wheel of the vehicular body is separated in order and the vertical wheels are traveled from the vehicular bottom walls to the bottom of wheels. CONSTITUTION:A hook vehicle 1 is positioned in the wheel sheath 24 of a travel rail 2, left and right-handed vertical wheels 15 are placed on wheel bottoms 23 and floated on the rail leg 28, and at the same time the hook shafts 12 are hung down from between slide grooves 26. The hook shafts 12 of two hook vehicles 1 are rotatably connected on the front and back sides of the upper end of a panel. The collision of wheels with the inner wall of the sheath 24 and the separation of wheels can thus be completely prevented to ensure the stable and good balanced traveling of wheels on the center line 20. |
