<p>PURPOSE:To simplify the structure and control by introducing such an arrangement that a moving element such as trolley runs while supporting with its supporting device an object to be transported such as car boy, and therein performing unlocking simultaneously with the rotation giving force for the supporting device. CONSTITUTION:When a self-running element 5 supporting a body 34 with a hanger device 16 as a supporting device runs along a rail 1, the detaining part 48 of a lock device 41 is detained with a detent part 45 from the inside, and this detention is maintained by the resilience of a spring and contacting with a stopper 51. Thereby an arm member 18 of the hanger device 16 is fixed to a coupling frame 13. When the body 34 is loaded or unloaded, a cylinder of an operational device is driven to sink a roller 62 at the bottom of piston rod, and now the part to be operated 49 is swung downward, and the detent 45 is disengaged from the detaining part 48. The following depression of a follower member 40 puts the arm member 18 in the condition of being moved open round a shaft 17.</p> |
