SUSPENDED TYPE TRACK CONVEYING TRUCK AND CONVEYING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a suspended type conveying truck and a conveying system allowing the conveying truck to place and carry out objects to be conveyed directly from a plurality of shelves of different height located off a position directly below the conveying truck while avoiding a cost increase and a fall of reliability caused by providing all the shelves of a shelf device with slide mechanisms in the conveying system for use in a semiconductor manufacturing plant. SOLUTION: The suspended type track conveying truck travels in a suspended state on a track laid at the ceiling and grips the objects to be conveyed by a liftable grip mechanism 22 to convey them. The grip mechanism 22 is provided with a slide mechanism 23 extensible in a horizontal direction, and a gripper 24 supported to the tip of the slide mechanism 23 to hold and release the object to be conveyed.
