Patent number: 9248844Abstract: The invention relates to an arrangement comprising a travelling mechanism girder and a running wheel block fastened detachably thereto, wherein the running wheel block is comprised of a housing with at least one connection surface and a running wheel which is mounted in the housing and protrudes out of the housing. To facilitate the exchange of running wheel blocks, alignment of the running wheel block with respect to the travelling mechanism girder is secured through the use of a machined groove, in which a machined plate is held in a form-fitting manner, arranged on the connection surface of the running wheel block. After the running wheel block has been properly aligned, the plate is fixedly connected to the travelling mechanism girder, maintaining the alignment. The invention also relates to a method for the installation of an arrangement consisting of a travelling mechanism girder and a running wheel block.Type: GrantFiled: April 12, 2012Date of Patent: February 2, 2016Assignee: Terex MHPS GmbHInventors: Thomas Schlierbach-Knobloch, Richard Kreisner, Gregor Jansen

Patent number: 8448578Abstract: A guide-roller arrangement for gantry cranes (1) has two rotatably mounted axial carriers (21) on which the guide rollers are seated. The guide rollers (11, 12) are mounted on journals which are arranged in the carrier plate (15) in a manner eccentric to the axis of rotation (41) of the axial carrier (21). The selected eccentric position of the journal can be fixed in a formfitting manner with the aid of toothing formations (29, 36) on the axial carrier and on the carrier plate.Type: GrantFiled: November 14, 2008Date of Patent: May 28, 2013Assignee: Konecranes PLCInventor: Markus Golder

Patent number: 8029710Abstract: Apparatus and methods are disclosed that are useful for robotic gantry systems that are lightweight while at the same time offering rigidity or stiffness for implementation in Contour Crafting construction and material delivery techniques. The present disclosure is directed to robotic gantry system and material transport apparatus that use of very light structural members that have sufficient compressive strength, but which may otherwise be weak in the presence of bending forces, in conjunction with cables that provide stiffness against bending. Use of such cables provides needed tension while at the same time allowing the robotic gantry system to be very light compared to solid structures, e.g., those with I-beams, etc. Material delivery systems including passive articulated arms are also disclosed.Type: GrantFiled: November 2, 2007Date of Patent: October 4, 2011Assignee: University of Southern CaliforniaInventor: Behrokh Khoshnevis

Patent number: 7793593Abstract: A gantry crane comprising a bridge communicating with a trolley. The two ends of the bridge are connected to a main column whose lower end is connected to rollers. Various hinged joints allow for movement of the components towards and away from each other which allows the crane to be assembled or disassembled without the need for elevated or hoisted operations.Type: GrantFiled: October 13, 2006Date of Patent: September 14, 2010Inventor: Xiaodong Huang

Patent number: 7597050Abstract: A crane return system is used for returning a crane component to a home position when there is a loss of power. A crane includes a bridge with a plurality of main wheels adapted to travel along at least one rail. The crane return system includes a plurality of auxiliary drive wheels supported by the bridge, the auxiliary drive wheels movable between a first position, in which the auxiliary drive wheels are recessed from the rail, and a second position, in which the auxiliary drive wheels are in contact with the rail. When power is supplied to the crane return system the auxiliary drive wheels are in the first position. A hydraulic fluid pressure vessel stores hydraulic fluid, wherein a substantially fixed mass of hydraulic fluid is contained within the crane return system, and a hydraulic cylinder is interconnected with the auxiliary drive wheels and selectively fluidly communicates with the hydraulic fluid pressure vessel.Type: GrantFiled: August 1, 2005Date of Patent: October 6, 2009Assignee: MHE Technologies, Inc.Inventor: Steven K.

Patent number: 7493864Abstract: A carriage is intended to be disposed transversely between essentially-parallel lateral girders. The carriage comprises stirrups that are disposed at the lateral ends and which each cooperate with a lateral girder in order to enable the movement of the carriage along the longitudinal axis (x) of the lateral girders; a central girder which is placed between the stirrups; first connectors which are provided between a first lateral end of the central girder and the first stirrup, and second connectors which are provided between a second lateral end of the central girder and the second stirrup. The aforementioned first and second connectors are arranged such as to enable the movement of one stirrup in relation to the other with six degrees of freedom and a limited amplitude.Type: GrantFiled: April 27, 2006Date of Patent: February 24, 2009Assignee: Cinetic LinkingInventor: Jean-Michel Corpelet

Patent number: 6733635Abstract: A coke oven buckstay moving device and method which can be used to quickly, reliably, and smoothly repair buckstays compared to conventional methods and devices. The coke oven buckstay moving means includes a main car, a subcar, a frame, and securing means. The main car is used when repairing pillered buckstays that support oven walls of the coke oven, and moves on a coke side platform or a machine side platform. The subcar is placed on the main car, and can freely move forward and backward in a direction of a lengthwise direction of the coke oven. The frame is provided in a standing manner on the subcar. The securing members are mounted to the frame and are used to grasp and secure the buckstays. According to the method, a damaged portion of the buckstay is secured to the subcar, cut, and then removed. Reversing the steps, a replacement buckstay is secured to the subcar, moved into position, and welded into place. The subcar is detached, and the oven repaired.Type: GrantFiled: December 22, 1999Date of Patent: May 11, 2004Assignee: JFE Steel CorporationInventors: Tatsuya Ozawa, Nozomu Tamura, Tetsuro Uchida, Nobuya Kamide

Patent number: 6622877Abstract: An overhead crane having an adjustable bearing assembly to adjust a wheel and axle of the crane in a horizontal direction in order to minimize skewing of the crane on a pair of parallel rails. A bearing retainer includes an outer surface sized to fit into an associated bore in an end truck of the crane, and an eccentric inner surface which engages the outer surface of a bearing. When the bearing retainer is rotated, the wheel and axle extending therethrough are moved in a horizontal direction. The bearing retainer includes a closed end having a surface which is engageable by a tool to allow for the rotation of the bearing retainer. A locking ring releasably fixes the bearing retainer and therefore the bearing to the frame of the crane as desired.Type: GrantFiled: June 4, 2001Date of Patent: September 23, 2003Assignee: MHE Technologies, Inc.Inventor: Thomas E.
