PROBLEM TO BE SOLVED: To lessen the axial misalignment and inclination of the coaxial shaft of a conveyor and the vibration of the conveyor by balancing the point of application of the lifting/lowering force of the conveyor in relation to the weight balance thereof. SOLUTION: A rotary telescopic mechanism 20 is arranged for vertical movement so that the lifting/lowering force of a lift mechanism 30 works on it in alignment with the substantial axis A of a coaxial shaft 21 provided thereon with a conveying arm assembly. This arrangement balances the point of application of the lifting/lowering force well on the center of gravity of a conveyor 1 to thus prevent an axial misalignment or inclination of the coaxial shaft 21 and a vibration of the conveyor 1. |
