  • Patent number: 6431816
    Abstract: A fluid power load-clamping system includes at least one fluid valve for variably regulating the maximum fluid pressure causing closure of the clamp. Preferably the valve increases the maximum fluid pressure automatically in relation to the measured magnitude of the weight of the load to regulate the load-gripping force. A controller causes the valve to permit a relatively high maximum fluid pressure as the clamp closes toward the load to enable high initial clamp closure speed. Thereafter the valve automatically reduces the maximum pressure as the clamping surfaces close into a predetermined relationship with the load, and then increases the maximum pressure to regulate the gripping force. Other preferable features include an automatic limit on the rate of lift of the load during weighing, and compensation of the weight measurement for the longitudinally-extensible position of the lifting mechanism, to maximize the accuracy of the load-weight measurement.

    Abstract: A method for handling conventional stacks of baked goods trays for the baking industry. A platen is moved underneath side-by-side stacks of trays. The platen supports the underside of the stacks of trays and prevents lateral movement of the bottom of the stacks by guiding the platen into channels that exist in the bottom of the trays. The platen is attached to an upright which is tiltable and which extends along one side of the baked goods trays when on the platen to support the stacks along their vertical height. Tilting of the upright causes the platen to lift and the trays to tilt against the upright where they are supported underneath and along the side and thus can be moved and handled. By utilizing the split platen and the tall tiltable upright with a motorized vehicle, an economical and efficient method of handing baked goods tray stacks is possible, eliminating significant manual labor and risk of worker injury.

  • Patent number: 5364224
    Abstract: A material storage hopper tiltably supported on the bed of a hopper support frame is disclosed, which frame is liftable either by a fork lift or a three point hitch such as used on farm and garden tractors. The frame is ground mountable such that the hopper can be used to store and dump materials while in a stationary, stand alone condition, separate and apart from the three point hitch of a tractor. The frame includes a bracket containing elongated slots in which a pin at the end of the third or central arm of a three point hitch is slidably inserted to permit the frame to level itself when elevated by the hitch above its ground mounted position. The slotted bracket also permits the frame to be self leveling when returned from an elevated to a ground mounted position.

  • Patent number: 5256023
    Abstract: An intermodal transportation system for hauling bulk materials, particularly municipal solid waste, by rail and truck utilizes multiple rectangular, open-top boxes each having a removable lid. The system includes a forklift with an articulated frame actuated by hydraulics which engages channels formed in the box or in the lid. Lock bars on the box are clamped by locking members carried on the forklift to hold the box on the forks during an over the-side dumping movement. The forklift empties the box with a roll-out motion combining a forward rotation of a lifted box with a backward movement of the box. A reinforced flatbed railcar receives up to four 21 foot long boxes and lids with a total carrying capacity of up to 100 tons. Each car contains upright corners that guide the boxes onto the railroad car and then restrain it. The containers are flush with the upper surface of the railroad car when engaged in the corners.

  • Patent number: 5244336
    Abstract: A mobile lifting apparatus having an extendable boom assembly supported by a plurality of hydraulic cylinders extending upwardly from a wheeled chassis, and further having a fork attachment coupled to the extendable boom assembly. The fork attachment is configured to engage palletized loads and permits such loads to be raised and transported upon extension of the hydraulic cylinders. The fork attachment includes a buttress assembly that remains relatively stationary as the boom assembly is horizontally extended and retracted. The fork assembly further includes a pair of forks that are pivotal relative to the buttress assembly around a generally horizontal axis. The forks are coupled to the horizontally extendable portion of the boom assembly so that extension and retraction of the boom pivots the forks to change the angular orientation of the forks relative to horizontal. Such angular movement of the forks facilitates engagement and disengagement of the forks with the palletized load.
