    Abstract: A facility for maintaining and servicing multiple units of equipment such as jet engines, after removal from an aircraft by conventional procedures, makes use of a multiple number of service bays serving as maintenance stations disposed on opposite sides of a central delivery way. An under hung bridge crane travels back and forth throughout the length of the central delivery way. Screw jacks at four corners of the crane are attached to and operate to elevate and lower a twin rail lifting bridge on which a jet engine unit is slung. The unit is supported by fixtures attached to trolleys which roll on the twin bridge rails. There is a mating twin rail lifting bridge in each bay with which the lifting bridge of the crane can temporarily interlock, so that the engine unit can be pushed on its trolleys from one lifting bridge to the other. Four corner located screw jacks also lift and lower the lifting bridge in each bay.

  • Patent number: 4316535
    Abstract: For use in a work processing line for workpieces, a workpiece storage system including a topologically closed loop track means having downwardly sloping surfaces coupled with elevators and lowerators in the loop, and work holding, gravity-operated pallets to run on said tracks having track engaging wheels equipped with retarding means responsive to wheel angular velocity and utilizing wheels of different diameters on the track depending on the loaded or unloaded condition of the pallets to control the speed of the pallets. Auxiliary track means, pallet loaders and unloaders, and switching mechanisms are incorporated in the system with elevators and lowerators to allow the storage system to function between multiple work processing lines, between single and multiple lines or between multiple and single lines to increase the flexibility of a work processing activity and reduce downtime.

  • Patent number: 4071135
    Abstract: A plurality of passenger cars are hung at equal intervals along an endless parallel chain and continuously travel in one direction between two horizontal platforms which are vertically spaced from each other and are maintained stationary with respect to the traveling of the cars. Guard plates are pivotably mounted to the outer wall surfaces of each car facing each the adjacent cars so that the plates can be rotated to fill the space between cars. Only when the cars horizontally travel along the platforms do the guard plates swivel to substantially hide spacings between the adjacent cars.

  • Patent number: 4070972
    Abstract: Propelling mechanism for forwarding a carrier of a power and free conveyor from the delivery end of a first carrier supporting track onto a track section of an elevator and thence onto the receiving end of a second carrier supporting track. The elevator includes a carriage to which the track section is attached and which is movable longitudinally to permit the track section to be extended from the elevator into registry with either the first or second carrier supporting track. A propelling member, consisting of a pair of roller chains connected in spaced side-by-side relation, is equipped at one end with a carrier pusher, is connected at the other end to an endless output chain of a reversible drive mounted on the carriage, and is supported and guided by tracks which extend parallel to the track section from the entrance end thereof and into a storage path parallel to the path of the endless output chain.

  • Patent number: 3952836
    Abstract: A composite transfer device for conveying material used in the construction of high tower-like structures, from a loading position at the base of the structure to a working platform which is raised as building proceeds. The device includes portions giving horizontal and vertical movement of a container, and includes a first transport unit at the loading level, a vertical hoist, and a second transport unit mounted on the working platform. The second transport unit includes a radial track movable around the working platform to deliver materials from the hoist, which is centrally situated, to different working areas around the structure. A special feature of the device is the use of a carrier frame which is square in plan view and which is supported on two hoist ropes attached to opposite corners of the frame, and which is also guided by guide tubes connected to the remaining two corners of the frame and which are located by downwards travelling reaches of the hoisting rope.
