Patent number: 9139403Abstract: The object of the invention is a bridge crane, which comprises a main girder, which is fitted to travel supported by end carriages essentially at both ends and which bridge crane further comprises a hoisting trolley traveling supported by the main girder and a rope drum mounted on bearings to rotate in an essentially stationary position, from which rope drum the hoisting rope is guided to a hook traveling along with the hoisting trolley. The hoisting rope is supported from below for at least a part of its essentially horizontal section.Type: GrantFiled: January 18, 2011Date of Patent: September 22, 2015Assignee: KONECRANES OYJInventor: Teppo Lindberg

Patent number: 8181799Abstract: An actuation system includes a bridge crane, a trolley, and an end effector and is configured for moving a payload. A first actuator is operatively connected to the bridge crane. The bridge crane is configured for moving along an X axis in response to the first actuator being actuated. The trolley extends from the bridge crane. A second actuator is operatively connected to the trolley. The trolley is configured for moving along a Y axis in response to the second actuator being actuated. The end effector extends from the trolley and is configured for supporting a payload. A third actuator is operatively connected to the end effector. The end effector is configured for rotating about the Z axis in response to the third actuator being actuated to rotate the end effector. Each actuator is disposed in spaced relationship to the bridge crane, the trolley, and the end effector.Type: GrantFiled: November 30, 2009Date of Patent: May 22, 2012Assignees: GM Global Technology Operations LLC, Universite LavalInventors: Thierry Laliberte, Clement Gosselin, Simon Foucault, Boris Mayer-St-Onge, Dalong Gao, Robert J. Scheuerman

Patent number: 7992733Abstract: An assist system is configured for moving a mass vertically, along a Z axis. The assist system includes a vertical actuation system, a cable, a plurality of pulleys, an actuator, and a mass. The pulleys are operatively attached to the support structure and an assist device that is movable attached to the support structure. The cable is routed around each of the pulleys and attached to the support structure. One of the pulleys supports the mass. The mass moves vertically in response to the actuator.Type: GrantFiled: November 30, 2009Date of Patent: August 9, 2011Assignee: GM Global Technology Operations LLCInventors: Thierry Laliberte, Clement Gosselin, Simon Foucault, Dalong Gao, Robert J. Scheuerman

Publication number: 20090308828Abstract: The rail mounted displaceable device is a ceiling mounted hoist comprising two pairs of carrying wheels (2) arranged to run in the rail (1) and two motion wheels (4) actuated by a motor (7). The motion wheels (4) are rotatably fixed on a hinged bracket (5) a hinge (6) to a chassis (3). The displaceable device is provided with an actionable solenoid (8) for pressing said transport wheels (4) against the rail (1) in order to allow a displacement of the device along the rail (1) when the motor (7) is activated and to allow the carrying wheels (2) to rotate freely along the rail (1) when said motor (7) is deactivated.Type: ApplicationFiled: March 29, 2007Publication date: December 17, 2009Applicant: Invacare International SarlInventor: Steen Hansen

Patent number: 7514885Abstract: Methods and systems for medical imaging are provided. The system includes a gantry assembly having a stator, a first rotor rotatably coupled to the stator, the first rotor configured to rotate about an examination axis at a first rotational speed, and a second rotor rotatably coupled to at least one of the stator and the first rotor, the second rotor configured to rotate about the examination axis at the first and a second rotational speed, the second rotational speed being greater than the first rotational speed, the first and second rotors configured to be locked in position with respect to each other during rotation at the first rotational speed, the first rotor configured to be locked in position with respect to the stator during rotation of the second rotor at the second rotational speed.Type: GrantFiled: March 8, 2005Date of Patent: April 7, 2009Assignee: General Electric CompanyInventors: Danny Hausner, Yaron Hefetz

Patent number: 6345724Abstract: A crane apparatus is disclosed. A hoisting accessory is traversed by rotating rotating drums by driving of a traversing motor to take up or pay out wire ropes. Continuously variable transmissions are provided for changing rotational speeds of the rotating drums. A control device controls the continuously variable transmissions in a gear changing manner so that forces imposed on the drums by the wire ropes will be balanced. Thus, torques acting on the pair of drums are canceled out in all areas in which the hoisting accessory moves, whereby the capacity of the drive motor can be reduced.Type: GrantFiled: August 2, 2000Date of Patent: February 12, 2002Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Masanori Masumoto, Hisanori Abiru, Tetsuo Ichikizaki, Takashi Chikura, Tatsuya Hirano, Shinichi Masumoto, Ikko Yasunaga, Takashi Okada

Patent number: 6023862Abstract: A control system for a rope bucket, the rope bucket being designed for the hoisting and transfer of materials and adapted to be suspended from a hoist trolley transferable along an essentially horizontal travel path. The control system includes a hoist mechanism for hoisting the rope bucket, and a close mechanism for closing and opening the scoops of the rope bucket, and also for hoisting and lowering the rope bucket. The hoist mechanism includes two separate mechanisms, and similarly the close mechanism includes two separate mechanisms which also form the transfer mechanism of the hoist trolley.Type: GrantFiled: September 23, 1998Date of Patent: February 15, 2000Assignee: KCI Konecranes International PLCInventor: Juhani Sirjola
