  • Patent number: 10480152
    Abstract: A swivelable adapter device for use with skid steer loaders consists of a mounting plate and a swiveling work tool plate for holding, rotating, and positioning various skid steer attachments. Rotation about a longitudinal axis of skid steer arms is accomplished using a barrel within a barrel assembly allowing work tool plate to be positioned from angles between horizontal and vertical. A mounting plate is attached to skid steer arms and is rigidly affixed to an inner barrel. An outer barrel with a notch plate and a work tool plate slides over a greased inner barrel. Swivel operation of the work tool plate is accomplished by hand eliminating the need for hydraulic systems. Once positioned, the work tool plate is locked to a notch plate using a locking latch. The swivelable adapter device is reinforced with metal plates to handle torsion forces created by heavy loads such as trees.

  • Patent number: 9969574
    Abstract: A wheelbarrow carrier provides transportation and dumping from a connection to a standard trailer hitch or tractor three-point mount. A pivoting ramp is used to load the wheelbarrow and a locking mechanism locks the wheelbarrow foot in place and the ramp in an upward position, once the wheelbarrow has been rolled onto the ramp and the ramp has pivoted from a downward position to an upward level position. The ramp pivots once the wheel of the wheelbarrow has rolled past the pivot point sufficiently to tip the ramp. Once the wheelbarrow is locked in the upward (level) position, a motor is activated to rotate a boom to which the ramp is attached with respect to a frame that is connected to the vehicle mount.

  • Patent number: 7699141
    Abstract: The invention is a device mounted on a forklift to provide the operator with information of the distance from the pallet load to the upright part of the fork/tines. The invention has a source of a range determining signal such as sonic waves but other signals such as infra red or radar waves may be used. The emitted signals hit the palletized goods and are reflected to a detector or sensor and processed. The range information is transferred to a distance display device. The range/distance between the upright part of forklift tines and the palletized load combined with knowledge of the length of floor parallel tines of the forks will provide information to prevent any excessive penetration of the pallet hollow which excessive penetration can cause damage to either truck trailer walls, warehouse structures, or other palletized loads.

  • Patent number: 5478196
    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.

    Abstract: Container handlers comprise a plurality of double-acting hydraulic cylinders to effect the various side shift, twist lock, tilt, height adjustment, and spread modes of operation. Separate control valves and hoses, entrained over the mast assembly having the attachment thereon, are required to effect such functions selectively. This invention is directed to a programmed electro-hydraulic control circuit when reduces the required number of hoses to two and provides a non-complex system which can be operated expeditiously.

  • Patent number: 4294572
    Abstract: An internal fluid communication system in combination with a fluid operated power cylinder, such as that used on industrial lift trucks, in which a pair of tubular sections in telescopic relationship is disposed lengthwise within the power cylinder, forming a fluid passageway through the cylinder for transmitting fluid from one end of the cylinder to the other. The cylinder may be of either the ram or the cylinder and piston type. Two or more tubular sections may surround the first tubular section and form a plurality of parallel fluid passages passing through the power cylinder from one end to the other without communicating with the operating fluid in the cylinder. In the embodiment of the invention applicable to a cylinder and piston type hydraulic motor, one tubular section is disposed in the piston rod and the other tubular section passes through the piston and is in telescopic relationship with the tubular section in the piston rod.
