  • Patent number: 4822237
    Abstract: Extended-reach lift apparatus for remote accessing of low-clearance areas is provided. The apparatus includes a vehicle whose frame supports a vertically pivotable telescoping boom which is elevatable by means of hydraulic rams. An extended tilt head is provided on the free end of the boom which includes parallel upper and lower link members of equal length. A work implement support having a discrete work implement tilting cylinder is attached to the remote ends of the upper and lower links of the tilt head. A hydraulic cylinder extending between the boom and the lower link of the tilt head provides separate tiltability of the tilt head while the design of the tilt head mechanically assures the maintenance of the attitude of the work implement without requiring additional hydraulic compensation during such tilting.

  • Patent number: 4802813
    Abstract: An elongated metal apparatus which comprises at least one longitudinal gripping member and preferably a pair of longitudinal gripping members in spaced apart relationship, which are anchored to a slab of concrete and can be used in conjunction with a forklift to physically lift and move the slab of concrete to another location to thereby expose the area beneath the concrete. The apparatus enables a user to remove a section of concrete without the necessity of breaking up and discarding the section of concrete and having to subsequently re-pour the concrete. The apparatus includes a central tunnel or channel for receiving a fork of a forklift, a pair of side members which permit the apparatus to be affixed to the concrete using anchor bolts, and a pair of covering members which cover the area of the anchor bolts to prevent then from flying out and injuring someone if one or more of the anchor bolts should shear loose during the lifting or moving process.

  • Patent number: 4793463
    Abstract: A turnover device for turning over articles as they are conveyed along a production path. The turnover device comprises a frame, two spaced apart and parallel axis, first and second carrier arms mounted respectively on the axes for rotational movement, first and second meshing gears mounted on the axes respectively, and a drive motor and lever. The first and second meshing gears have pitch diameters such that, as the two carrier arms counter-rotate from a start position to a finish position, the first carrier arm will rotate through an arc of approximtely 108.degree. and the second carrier arm will rotate through an arc of approximately 72.degree.. The arms are then rotated to their start position. An article placed on a first carrier arm will drop off onto the second carrier arm and be carried back down to a horizontal orientation which is flipped end to end with respect to its starting orientation.

  • Patent number: 4792036
    Abstract: A transporting device of the conveyor belt type, in which a transporting belt, on which the material to be transported can be supported, is capable of being moved along a transport path by a driving mechanism and carried using rolling bodies. The transport path is equipped with an electrical travelling-wave stator (10). Permanent magnets (16) are provided arranged in series, which communicate with the transporting belt (20) in a power-transmitting fashion and form a linear motor with the travelling-wave stator (10) with an air-gap between the pole faces of the attracting permanent magnets (16) and the travelling-wave stator (10). The permanent magnets (16) and the travelling-wave stator (10) are held at air-gap space (a) by rolling bodies (14).

  • Patent number: 4792272
    Abstract: A container handling apparatus having a pair of side frames and a cross frame. The apparatus also has four lift mechanisms for attachment to a container. Each lift mechanism is mounted on one end of a secondary lift arm. Four primary lift arms are connected to the side frames and to the midpoint of each of the secondary lift arms. A cam follower on the lower end of each secondary lift arm follows a cam horizontally along one of the side frames. Hydraulic cylinders rotate the primary lift arms about a pivot connection to the side frames. This causes the upper ends of the secondary lift arms to move vertically to raise and lower the lift mechanisms and the container. Transducers connected between the primary arms and the side frames equalize the amount of rotation of each of the primary lift arms and automatically keep the positions of the four lift mechanisms at the same height.

  • Patent number: 4738353
    Abstract: In belt conveyors having two parallel belts (1) with feeders, movement of the belts must be synchronized. The known method of achieving this is by means of electrical systems. The present invention entails a radical simplification of this synchronization by using a single belt (1) crossing over below the conveyor, the two parallel sections on the upper side of the conveyor thus moving snychronously. The conveyor according to the invention is less expensive and more reliable than previously known conveyors, nor is it dependent on a source of electric power.
