Abstract
A suspension type transporter suspends a bolt drawing machine through a trolley and a hoist above a pressure container having many bolt attached thereto and transports the bolt drawing machine to a target position. A track settling portion having a guide is provided on an outer periphery of a lid of the pressure container. The suspension type transporter for the bolt drawing machine comprises a guide mechanism which restricts movement of the bolt drawing machine in the air by the guide. The guide mechanism of the transporter is provided with a position detector which can detect a position of the bolt drawing machine. A positioning controller of the suspension type transporter controls the transporter so that the transporter starts at slow speed, is then accelerated to a prescribed speed and is gradually decelerated near the target position.
