Abstract: Systems, methods and apparatus for automated vehicle wheel removal and replacement are provided. One system includes a computer system with applications for scheduling the replacement of tires for the vehicle. An electronically controlled lift device and robotic apparatus is configured for interaction with the computer system. The lift device mechanically adjusts arms for placement on lift points of vehicles. The robotic apparatus detects positioning of lug nut configuration for a wheel, removes lug nuts, and then removes the wheel from the wheel hub with gripping arms. The wheel and tire are then handed off to a separate tire changing machine. When a new tire is replaced the robotic apparatus then mounts the wheel to the original wheel hub, and then secures the lug nuts to the lug nut bolts.

Disclosed more particularly are a method and system for testing an overhead crane runway beam 3D alignment or an overhead crane runway rail 3D alignment using a 3D laser scanner.

Abstract: The present disclosure relates to a rotary joint for rotatable connection of the uppercarriage with the undercarriage of a crane, wherein they can each be connected with the uppercarriage on the one hand and the undercarriage on the other hand via a quick-release coupling.

Abstract: The lifting device according to the invention comprises a carriage (16) and a lifting unit (17), which are connected to each other by means of linear guides (29, 30). The carriage (16) comprises two side parts (19, 20) that can be adjusted in view of their distance relative to each other by means of a distance adjustment device (36). In doing so, they are centered by means of a centering device (45) with respect to the lifting unit (17), in particular with respect to the pulling means originating from the lifting unit (17).

Abstract: The invention provides a trolley wheel assembly for a conveyor system, e.g., an overhead conveyor system. In certain embodiments, the wheel assembly includes at least one wheel face having a contour (optionally a funneling configuration and/or one or more surface features) configured to facilitate flow of a fluid toward an open bearing assembly of the wheel assembly. In some embodiments, the wheel assembly includes an inner race, outer race, and bearings having a particular hardness arrangement, optionally together with a polymer wheel having certain filler features. Methods for cleaning such a trolley wheel assembly are also provided.

Abstract: A body-weight support system that allows individuals with severe gait impairments to practice over-ground walking in a safe, controlled manner is disclosed. The system includes a body-weight support system that rides along a driven trolley and can be controlled in response to the movement of the subject using the system.

Abstract: A hoist for a low space crane is disclosed, which comprises a hoist frame in which a load point transferred to a girder is positioned at a vertical surface of one side of the girder, and a balance of a biased load is maintained for thereby decreasing an entire weight of the system, and an equal distribution unit which installed between the hoist frame and the guide rail for absorbing an impact load transferred to the hoist frame and equally distributing the entire vertical load. A buckling phenomenon does not occur at the girder even when a relatively heavy object is transferred by providing the first and second support wheel parts on the first vertical surface of the girder.

Abstract: The invention relates to a chassis (1) for a cable or pipeline trolley (2), for travelling along a carrier rail, said chassis comprising at least one pair of carrier rollers (3) with a horizontal rotational axis and at least one pair of guide rollers (4) with a vertical rotational axis. The disadvantage of known chassis of this type is that they jolt at uneven sections of the carrier rail and a significant supply of replacement parts is required for repairs. The aim of the invention is to develop a chassis with improved driving characteristics, whilst at the same time reducing production and inventory costs. To achieve this, the carrier rollers (3) and guide rollers (4) are essentially arranged asymmetrically to a vertical axis (5).

Abstract: The object of the present invention is to provide a trolley for loading able to comply with a force other than a direction of movement based on a premise of usage of a circular pipe as a rail. The present invention is a single-track suspension trolley for loading applied to a single rail, of which at least an upper half part is formed in arch, having a V-shaped groove having symmetric taper planes slanting to a center at midspan, having a drum-shaped wheel running on the rail while the taper plane of the V-shaped groove is in a contact condition with the upper half part in two points, having a flame provided with a pivot side plate enabling to roll the wheel, and having a cargo handling member provided with the flame beneath the wheel. A wheel is connected integrally with a pair of piece having a conical surface, each of which is faced or a V-shaped groove is produced at a center of a cylindrical member by abrading thereof.

Abstract: A fall protection system has at least two widely spaced apart support members which support a rail assembly above a work area. The rail assembly includes a beam and a truss member. The beam has a generally vertical web and at least a lower generally horizontal flange. A trolley is adapted to slide or move across the flange. The truss member is mounted to a top of the beam and extends the length of the beam.

Abstract: A portable hoist is provided for lifting and moving heavy loads a short distance. The hoist has a rectangular frame which supports a movable carriage containing a winch and pulley. The rectangular frame is adjustable along corner legs which allows individual leg adjustment. Parallel longitudinal side frame members include tracks and channels for rollers to support and direct the carriage along the frame. The winch can be operated by an electric hand drill to enable an individual to move and lift several hundred pounds without assistance.

Abstract: A gantry truck assembly for rolling on a rail (16) where the rail has a top rail surface (42) and a side rail surface (48). The truck has a wheel (38) for rolling on the top rail surface. A flange (44) extends radially from the wheel and can contact the side rail surface (42). A side roller (56) is rotatably mounted to a lever arm (54) and is biased by a spring (62) to a position closer to the side rail surface than is the wheel flange. When a force greater than a pre-set limit is placed on the roller by the rail, the lever arm can pivot to allow the wheel flange to contact the side rail surface.

Abstract: The invention is a crane system for a building for the assembly of a gas bag for a lighter-than-air vehicle, the building having a floor and a roof thereover with a longitudinal, vertical and lateral axis. In detail, the crane assembly includes a plurality of crane carriage rail assemblies in the form of arches aligned with the lateral axis of and mounted within the building. The carriage rail assemblies are in a spaced relationship along the longitudinal axis. A plurality of crane carriages are movably mounted on each of the crane rail assemblies with each carriage including a winch mounted thereon having an extendible and retractable cable. A control system is provided for moving the crane carriages by rows aligned with the longitudinal axis of the building along the crane carriage rail assemblies to specific locations along the lateral axis and for adjusting the length of the cables of the winches in each of the rows as a function of the distance of each of the rows along the lateral axis of the building.

Abstract: A transfer system for controlling and initiating the flow of metered amounts of materials which may be radioactive ash, radioactive calcined salts, cement, flour, or pharmaceuticals comprising a vertical non-converging conduit which acts as a storage hopper; a stationary platform located at the downward end of the conduit to allow the radial outward flow of the material; a translatable hollow piston that acts externally but coaxially to the conduit and platform to interrupt the radial flow of material; a hopper located below the platform for accepting the material; and a housing that encloses and supports the hopper and platform and provides a dust tight seal around the apparatus of this invention.
