Publication number: 20220289530Abstract: A changing device easily and safely changes the posture of the backstop of a crane between a support posture and a storage posture. The backstop posture changing device is provided with a first support member, a second support member, a push-up mechanism, and a connection member. The first support member and the second support member are rotationally connected to a backstop and a lower boom respectively. When a cylinder rod of the push-up mechanism is extended with respect to a cylinder body, a push-up member pushes up the first support member and the posture of the backstop is changed from a storage posture on the lower boom to a support posture in which it is possible to support a boom while the crane is in a working posture.Type: ApplicationFiled: August 28, 2020Publication date: September 15, 2022Applicant: KOBELCO CONSTRUCTION MACHINERY CO., LTD.Inventors: Eiji MIYA, Taisuke TSUNOO, Hitoshi SAKURAI, Hideo INOUE, Kouichiro NAGAI

Patent number: 9206021Abstract: Provided is a crane which comprises a luffing jib including a lower jib and an upper jib coupled to the lower jib in such a manner as to be separable from the lower jib, the lower jib is attached to a head of a boom to have a laid-down posture at a position between the boom and a strut when the upper jib is separated from the lower jib, when the boom is lowered and laid down to allow the head of the boom to come into contact with a ground and when the strut is lowered and laid down to allow a distal end of the strut to come into contact with the ground, and the lower jib has a length which causes no interference with the strut when the lower jib has the laid-down posture at the position between the boom and the strut.Type: GrantFiled: September 20, 2013Date of Patent: December 8, 2015Assignee: KOBELCO CRANES CO., LTD.Inventors: Hitoshi Kurotsu, Teppei Maedo, Eiji Miya, Keiko Inada

Patent number: 9139404Abstract: Disclosed is a raisable-lowerable member which comprises a boom and a jib. The boom comprises a first supporting portion configured to rotatably support a jib foot when the jib is set in a protruding posture; and a second supporting portion configured to rotatably support a supportable portion of the jib when the jib is set in an enfolded posture. A position adjusting and holding unit of the jib is configured to couple, to the frame, a specific site of the second link in such a manner that a relative position of the second link with respect to the frame in a rotational direction of the second link is adjustably changed to allow the rotational axis of the second joint portion to become coincident with the rotational axis of the jib foot, and to hold the second link at the changed relative position.Type: GrantFiled: March 14, 2014Date of Patent: September 22, 2015Assignee: KOBELCO CRANES CO., LTD.Inventors: Keiko Inada, Hitoshi Kurotsu, Daisuke Takaoka, Yasuo Ichikawa, Eiji Miya

Patent number: 8827091Abstract: [PROBLEMS] To provide a rotating frame of an upper rotating body such that total productivity can be improved, the cost can be reduced, and model change can be facilitated. [MEANS FOR SOLVING PROBLEMS] Many models having different lifting capacities are divided into a plurality of classes each including a plurality of models. A rotating frame 17 is determined on the basis of the model having the largest lifting capacity in each class. An upper rotating body is constructed using the rotating frame 17 as the base. In addition, each of winches 5 to 7 is mounted on the rotating frame by using a mounting structure standardized in the same class. On the other hand, left and right deck frames 18 and 19 are divided into sections on which different pieces of equipment are mounted, and the sections are separately attached to the rotating frame 17.Type: GrantFiled: March 31, 2005Date of Patent: September 9, 2014Assignee: Kobelco Cranes Co., Ltd.Inventors: Shozo Yokoyama, Tomohiko Murata, Kenji Onuki, Hirohito Sato, Kunio Wakamatsu, Shinji Goto, Yutaka Kobayashi, Eiji Miya

Patent number: 7216774Abstract: The present invention provides a crane where a spreader retainer is disposed on a rear surface of an extreme end of the lowest boom portion used both for a tower boom and a normal boom, a distance between an upper spreader, which constitutes a boom raising/lowering apparatus, and a lower spreader at the maximum boom raise angle and the length of the lowest boom portion are set such that the upper spreader can be lowered to the position of the spreader retainer if the boom raising/lowering apparatus lays the boom on the ground, and a boom raising/lowering rope is then loosened for disassembly of either the tower or normal boom. Consequently, the upper spreader can be lowered to the position of the spreader retainer on the lowest boom portion when the boom is disassembled either for the tower crane or normal crane specification.Type: GrantFiled: October 19, 2004Date of Patent: May 15, 2007Assignee: Kobelco Cranes Co., Ltd.Inventors: Tokihiko Mizuta, Osamu Toudou, Keisuke Fukumoto, Eiji Miya, Yasuhiko Murayama

Patent number: 6386698Abstract: A method of transfer printing for increasing the reproducibility in achieving high-precision, high-brilliance transfer prints by controlling the print density of yellow sublimate ink on the transfer material within a specified range of yellow density. The invention has application in transfer printing methods where a digitized image is produced on a transfer material by printing the image from a PC by a ink jet printer using sublimate ink. The printed image on the transfer material is transferred to a print medium by heat processing. The other colors of the image are adjusted based upon the print density of yellow sublimate ink falling within the specified range.Type: GrantFiled: June 13, 2001Date of Patent: May 14, 2002Assignee: Megami Ink Mfg. Co., Ltd.Inventors: Shoji Suga, Eiji Miya, Hideo Uchida, Tadao Arai
