And there is a disadvantage that the loud noise and vibration occurs in the trolley chain.

Such noise and vibration has a problem that greatly damages the working environment to reduce the work efficiency of the worker. In particular, since a large shock is transmitted from the hook and the trolley chain when accelerating from low speed to high speed or decelerating from high speed to low speed, such a repeated shock often causes a failure in the equipment.

In addition, the conventional ceiling-running logistics conveying system improves the speed as the conveyed objects are arranged at predetermined intervals suitable for low-speed conveyance for the worker's assembling work, so that the conveyed objects are improved at high speed. There is a disadvantage that the distance is secured a lot. Accordingly, there is a problem that the number of conveyed objects conveyed per unit time is small based on the same conveyance speed.

In addition, there is a disadvantage in that the number of objects to be transported and stored in the high-speed transport section is small in view of the role of the logistics transport system to temporarily hold and transport the objects to be processed between processes.

In order to solve the problems described above, the present invention is a ceiling running type that can reduce the noise, vibration and acceleration and acceleration and deceleration shock when the conveying object at high speed, and can reduce the distance between the conveying objects to a minimum during high speed conveyance.
