  • Patent number: 4529066
    Abstract: In a mast crane wherein a tension member controls the position of a carriage along an upright guide rail, the tension member is connected with a load transmitting element against which an abutment on the carriage bears down under carriage weight. A brake shoe carrier that has a link connection with the carriage carries two brake shoes, and by swinging about said link connection it clampwise engages them against opposite carriage-guiding surfaces on the rail. A linkage connecting the load transmitting element with the brake shoe carrier causes brake-engaging swinging of the carrier when the load transmitting element drops away from the abutment upon failure of the tension member. A spring biases the brake shoe carrier for such swinging, but its force is normally overcome by weight of the carriage. The link connection of the brake shoe carrier with the carriage is arranged for brake self-energizing once the brake shoes engage the rail.

  • Patent number: 4370932
    Abstract: An apparatus is provided for the interconnection of two mobile carriages which are connected by a rigid beam and guided along parallel guide rails. The apparatus permits the simultaneous and identical movement, with respect to both direction and distance, of the carriages along the respective guide rails. The apparatus comprises two generally symmetrically disposed cables, each of which is attached at one end to an end of one rail and at its other end to a diagonally opposed end of a parallel rail. Intermediate the attachment points, the cables connect the carriages by resting on and being supported by return pulleys which are integral with the carriages. Each cable thereby describes a generally Z-shaped configuration. The Z-shaped configurations are symmetrically disposed in order to cause, during the displacement of one carriage, the tensioning of one of the cables, and thereby cause the other carriage to be identically and simultaneously displaced.

  • Patent number: 4286911
    Abstract: A semi-automated warehousing system for unitized loads, such as load carrying pallets, which are retained in storage racks arranged in a multiple lane, multiple tier array, is disclosed. The system employs a man operated stacker crane that travels upon a fixed rail and serves as a host vehicle for a radio controlled transfer vehicle which is powered by a rechargable battery. An elevator, which forms part of the crane, is mounted between masts of the crane and a man carrying cab is secured to the elevator. The transfer vehicle can move laterally away from the crane, in either direction, in response to radio command signals controlled by the operator in the cab. The transfer vehicle rides on support rails in the storage rack and, upon command, deposits or picks up a pallet. The battery which powers the transfer vehicle is recharged each time the vehicle returns to the elevator portion of the crane.
