摘要:
A hanging-type transport apparatus for bolt-pulling machine, which transports a bolt-pulling machine hanging therefrom via a trolley and a hoist over a pressure vessel on which many bolts are mounted. The transport apparatus has a track setting unit with a guide along the outer periphery of a cover of the pressure vessel, and has a guide mechanism based upon the guide to restrict the degree of freedom of the bolt-pulling machine in the air. The guide mechanism is provided with a position detector to detect the position of the bolt-pulling machine. The invention further relates to an apparatus for controlling the positioning of the transport apparatus, such that the hanging-type transport apparatus is started at a slow speed, gradually accelerated to reach a predetermined speed, and is gradually accelerated to reach a predetermined speed, and is gradually decelerated prior to reaching a desired stop position.
