Patent number: 4883185Abstract: 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.Type: GrantFiled: November 2, 1987Date of Patent: November 28, 1989Assignees: The Hokkaido Electric Power Co., Inc., The Kansai Electric Power Co., Inc., Shikoku Electric Power Co., Inc., Kyushu Electric Power Co., Inc., The Japan Atomic Power Company, Mitsubishi Jukogyo Kabushiki Kaisha, The Japan Steel Works, Ltd.Inventors: Takashi Fujitani, Hiromi Uemura, Toshiaki Kishimoto, Masayuki Uchiyama, Isao Shirasu, Hideyuki Kurokawa, Takashi Nishioka, Kenji Kikukawa, Yoshinori Sato
