Appl. No.:

10/092833

Inventors:

Daniel J. Olson - Orland Park IL

Assignee:

Mi-Jack Products, Inc. - Hazel Crest IL

International Classification:

B60P 300

US Classification:

212273, 212343, 414460, 414591

Abstract:

A hydraulic system for actuating opposed arms of a grappler for a gantry crane dampens swaying motion of the arms. Within a conduit which carries pressurized fluid to and/or from actuators to pivot the arms, a dampener includes a restrictor having an orifice to restrict the flow in at least one direction. Each of the dampeners can include a respective check valve to permit free flow through one direction of the conduit and to direct reverse flow through the orifice. In a specific embodiment, a load is received between opposed arms of the grappler to seat upon shoes which extend inwardly from the arms. To urge the shoes to remain in secure lifting contact under the load, flow is restricted when the swaying load moves the arm outwardly, permit free motion of the arm when the swaying motion pulls the arm inwardly.

International Classification:

B66C013/04

US Classification:

212270, 212272, 212276, 294907

Abstract:

A system and process are provided for controlling motion of a grappler of a gantry crane to avoid damaging an object to be lifted. In an embodiment, a speed of grappler movement is automatically reduced when in close proximity to the object. Furthermore, the grappler automatically stops when positioned appropriately to permit a latching mechanism to engage the object for lifting. Normal speed grappler motion is restored when the latching mechanism is fully engaged. In a particular embodiment, the grappler includes a plurality of height sensors at various positions along the grappler to determine the respective height of the grappler above a top of the object. Vertical motion of front and rear ends of the grappler are independently actuated and controlled to permit appropriate control when the grappler and/or the object are not level.

International Classification:

F04B 49/00
F16D 31/02

US Classification:

417 34, 60431

Abstract:

A control system and method for obtaining power on demand from a diesel engine in order to operate vehicle functions and accessories. The method comprised of: (1) determining a flow rate necessary to operate each of a plurality of function hydraulic pumps and an vehicle drive pump associated with the engine; (2) comparing the flow rates of the various hydraulic pumps to determine the greatest flow rate; (3) establishing an engine speed necessary to deliver the greatest flow rate; (4) comparing the engine speed necessary to deliver the greatest flow rate with a current engine speed; and (5) adjusting the current engine speed to provide the greatest flow rate required.

Abstract:

The packaged medical article can comprise the medical article and a protective layer capable of inhibiting exposure of the medical article to a color change activator prior to use of the medical article. The medical article comprises a plastic portion and an active color changing specie, wherein the color changing specie is capable of changing color after exposure to a color change activator. The method for producing a medical article can comprise: combining thermoplastic resin with a blocked color changing specie to form a resin mixture and manufacture processing the resin mixture to form a packaged medical article. This manufacturing processing comprises forming the resin mixture into the medical article and packaging the medical article to form a packaged medical article. The color changing specie will not affect the structural integrity of the medical article when it changes color.

Daniel Olson - Orland Park IL, US

International Classification:

B66C001/66

US Classification:

294/081510

Abstract:

A swing arm style grappler for a gantry crane is equipped with contact shoes configured to engage in horizontal, flush contact at the underside of a standard load. The grappler includes a plurality of pivotable arms movable between an unclamped position, wherein the arms are positioned outwardly free from the load, and a clamped position wherein the arms are positioned inwardly to clamp the load. Each of the arms has an elongate portion, one of the shoes being mounted to a lower end of the elongate portion. The shoe includes a lifting shelf which projects generally inwardly at an angle such that, when the arms are in the clamped position, the shelf is horizontal.

International Classification:

H04N 718

US Classification:

348 61

Abstract:

In a gantry crane having a movable grappler adapted for lifting standard containers, a system is provided to aid in positioning the grappler relative to the container. The grappler is equipped with at least two corner video devices located near corners of the grappler for viewing the corner locking holes of a container below. In an embodiment, an additional distal video device is mounted to a side of the grappler opposite the cab to view the relative orientation of a side of the container relative to the side of the grappler. In an embodiment, a plurality of alignment sensors are mounted to respective sides of the grappler to detect the relative position of corresponding sides of the container vertically below. In an embodiment, a pair of height sensors are mounted to the grappler to measure a height of the grappler above the upper surface of the container. Additionally, indicators are provided in the cab to indicate information transmitted from the alignment sensors and/or height sensors.
