  • Patent number: 5909996
    Abstract: A wheel lift head assembly is pivotally mounted adjacent the rear end of a truck frame and is hydraulically operated for raising and lowering one end of a vehicle to be towed behind the truck. The wheel lift head assembly includes a crossbar member having a pair of hollow tubes pivotally mounted at opposite ends thereof with a pair of J-shaped wheel engaging members slidably mounted therein. A retainer is secured to an end of each J-shaped arm to prevent the withdrawal of the arm from the pivoted guide tube and a J-shaped arm provides engagement on opposite sides of the wheels of the vehicle to be towed to prevent lateral slipping of the wheels. A tiltable truck bed is mounted on the truck for pivotal movement between a horizontal position and an inclined position. At least one support post is provided at the rear of the tiltable truck bed for supporting the end of the tiltable truck bed on the ground and notches are formed in a forwardly facing surface of the support post.

  • Patent number: 5897282
    Abstract: A catalyst loading system for utilizing catalyst from a bulk supply located adjacent but not on the upper tube sheet of a catalytic reactor and for mechanized measuring of multiple identical quantities of catalyst and for mechanized loading of catalyst pellets into the reaction tubes of the reactor to achieve even drop rate, compaction and outage of the reaction tubes. From the bulk supply, multi-compartment catalyst charging hoppers are individually filled in rapid and accurately measured fashion by mechanized filling equipment having a predetermined sequence of operation that ensures accuracy of volumetric catalyst measurement. The charging hoppers are used for delivery of measured volumes of catalyst of a reactor tube loading mechanism which may take the form of a mobile cart framework being selectively positionable relative to the upper tube sheet and reaction tubes of a catalytic reactor to be charged with catalyst pellets.

  • Patent number: 5897285
    Abstract: A cargo truck is provided having a loading ramp assembly to aid in loading and unloading items from a cargo box on the truck. The loading ramp assembly is adjustable between a loading position wherein a ramp is provided between a deck of the cargo box and the ground, and a storage position to allow transport of the cargo truck. The loading ramp fits within a pocket between the truck frame and the cargo box when in the storage position. The pocket is formed by long C-shaped box sills that support the cargo box. The ramp is formed by two side rails, a ramp floor between the side rails, and support braces between the ramp floor and the side rails to prevent buckling of the side rails upon application of a load to the ramp. The braces extend below the bottom of the box sills when the ramp is in a storage position. The braces allow for lower profile side rails, thereby reducing the amount the cargo box must be raised above the truck frame to accommodate the ramp assembly.

  • Patent number: 5897288
    Abstract: A fork for a fork lift truck is attached to the typical mast mounted carriage by means of upper and lower hangers. Lateral adjustment of the position of the fork relative to the carriage involves engagement and release of a pin structure carried by the upper hanger. The upper hanger incorporates a pin which is vertically movable between a first position in which the pin engages slots in the upper mounting bar of the carriage and a second position in which the pin is recessed permitting lateral, relative movement between the fork and the carriage. A spring urges the pin to the first position where the pin engages slots in then carriage mounting bar. By lifting and turning the pin can be held in a second position so that the fork is slidable laterally along the carriage mounting bar.

  • Patent number: 5893696
    Abstract: A High-rise Automated Garage (HAG) for offstreet parking consists of up to 40 stories (levels) car storage structure and a bank of elevators in the middle of this structure. Elevators are oriented along the garage and can pick-up cars from a flat driveway along the garage. Car handling carriages of the elevators can lift cars as cargo, using their wheels as the pick-up points, and move them horizontally into elevator's platform. In the case of one elevator failure, cars parked in the zone served by this elevator can be relocated by attendants into the zone served by an operating elevator, thus providing the capability of returning cars to the owners in a reasonable time. HAG has two loading (unloading) lanes. This allows an increase in the driver time for arriving and releasing the car to two elevators' cycles.

  • Patent number: 5890867
    Abstract: A dump truck having a dump body which includes a rotatable feedgate for adjusting the size of a passageway through a rear opening at the rear of the dump body. The rotatable feedgate is rotatably mounted within the rear opening to provide for improved control of the flow of materials within the dump body which pass through the rear opening when the feedgate is positioned into an open position. A side guide is incorporated into the rotatable feedgate to provide additional control of the flow rate of materials through the rear opening especially at low feed rates. The rotatable feedgate design includes a rotatable feedgate position for open mode hauling whereby the feedgate is repositioned in the rear of the dump body. An opening plate is also provided to be used to provide an alternative arrangement for sealing the tailgate opening while the rotatable feedgate is attached or detached from the dump body.

  • Patent number: 5888048
    Abstract: A system for automatic loading of wafer boats onto a cantilever paddle for insertion of the wafer boats into a furnace tube includes an end effector carriage moving on a track and supporting an end effector having spaced, parallel pads to engage opposed outer side portions of a wafer boat. The end effector receives a wafer boat from a robotic arm of an elevator. The robotic arm moves transversely relative to the track to position the wafer boat over the track on which the paddle carriage moves. The end effector carriage moves the end effector pads under the wafer boat, lifts it from a pair of elevator tines, moves the wafer boat over a desired part of the paddle, and lowers the wafer boat onto the paddle. The end effector carriage then returns the end effector to an initial location.

  • Patent number: 5885045
    Abstract: A system includes an interface for receiving a pod having a carrier that receives wafers, and that is initially enclosed within a base and a pod cover. The system also includes a mechanism that transfers an exposed carrier between the interface and a platform of a mass-transfer machine included in the system. The machine includes a gantry arm for transferring the carrier between the platform and a transfer station. A retainer assembly is positionable over the carrier at the transfer station, and over a process carrier that is used in a processing tool. Moveable retainers of the assembly receive and hold wafers. The machine includes an elevator that moves between the transfer station and the process carrier. The elevator extends and retracts for transferring wafers between the retainers and either the carrier or the process carrier. A turntable, that receives the process carrier, permits automatically reorienting wafers.
