Abstract

An apparatus is described for deicing an aircraft in one pass of the aircraft through the apparatus with the apparatus including a pair of spaced-apart deicing devices. Each of the deicing devices comprises a vertically disposed support tower having an upstanding boom pedestal rotatably mounted on the upper end thereof. An elongated, telescopic boom assembly is pivotally mounted on the pedestal for selective extension and retraction with respect thereto. An elongated support is pivotally mounted on the outer end of the boom assembly and has an operator'"'"'s cab selectively movably mounted thereon. Spray nozzles are mounted on the operator'"'"'s cab to enable the operator to spray deicing fluid onto the aircraft.

Claims

1. An apparatus for deicing an aircraft in one pass of the aircraft through the apparatus, comprising a pair of spaced-apart deicing devices, each of said deicing devices comprising:

a vertically disposed support tower having upper and lower ends;

said lower end of said support tower being rigidly fixed to a supporting surface;

an upstanding boom pedestal rotatably mounted, about a vertical axis, on the upper end of said support tower;

an elongated, telescopic boom assembly having inner and outer ends, pivotally mounted about a horizontal axis on said pedestal for selective extension and retraction with respect thereto;

an elongated support, having inner and outer ends;

said inner end of said elongated support being pivotally mounted, about a horizontal axis, to said outer end of said boom assembly;

an operator'"'"'s cab selectively movably mounted on said outer end of said elongated support;

at least one deicing spray nozzle mounted on said operator'"'"'s cab for spraying deicing fluid onto an aircraft;

said deicing spray nozzle being in fluid communication with a source of pressurized deicing fluid.

2. The apparatus of claim 1 wherein said operator'"'"'s cab is rotatably mounted, about a horizontal axis, to said outer end of said elongated support.

3. The apparatus of claim 1 wherein said elongated support includes an automatic cab leveling device for maintaining said operator'"'"'s cab in a predetermined attitude regardless of the angular position of said boom assembly with respect to said pedestal.

4. The apparatus of claim 1 wherein said support tower is hollow to permit the passage of electrical wires, hydraulic lines, and deicing fluid lines therethrough.

5. The apparatus of claim 4 wherein said pedestal has an interior passageway formed therein to permit the passage of electrical wires, hydraulic lines, and deicing fluid lines therethrough.

6. The apparatus of claim 2 wherein a hydraulic motor is provided for rotating said operator'"'"'s cab with respect to said elongated support.

7. The apparatus of claim 1 wherein said operator'"'"'s cab is enclosed.

8. The apparatus of claim 1 wherein said boom assembly comprises an outer boom section having inner and outer ends, at least one intermediate boom section having inner and outer ends, and an inner boom section having inner and outer ends;

said inner end of said outer boom section being pivotally secured to said pedestal;

said inner end of said elongated support being pivotally secured to said outer end of said inner boom section.

9. The apparatus of claim 1 wherein said boom assembly includes a supporting means for supporting electrical wires, hydraulic fluid lines, and deicer fluid lines thereon.

10. The apparatus of claim 9 wherein supporting means includes at least one tube member longitudinally movably mounted on said boom assembly which has the electrical wires, hydraulic fluid lines, and the deicer fluid lines extending therethrough.

11. The apparatus of claim 9 wherein said supporting means includes at least one linked carrier having the electrical wires, hydraulic lines, and deicer fluid lines mounted thereon.

12. An aircraft deicing apparatus, comprising:

a vertically disposed support tower having upper and lower ends;

said lower end of said support tower being rigidly fixed to a supporting surface;

an upstanding boom pedestal rotatably mounted, about a vertical axis, on the upper end of said support tower;

an elongated, telescopic boom assembly having inner and outer ends, pivotally mounted about a horizontal axis on said pedestal for selective extension and retraction with respect thereto;

an elongated support, having inner and outer ends;

said inner end of said elongated support being pivotally mounted, about a horizontal axis, to said outer end of said boom assembly;

an operator'"'"'s cab selectively movably mounted on said outer end of said elongated support;

at least one deicing spray nozzle mounted on said operator'"'"'s cab for spraying deicing fluid onto an aircraft;

said deicing spray nozzle being in fluid communication with a source of pressurized deicing fluid.

13. The apparatus of claim 12 wherein said operator'"'"'s cab is rotatably mounted, about a horizontal axis, to said outer end of said elongated support.

14. The apparatus of claim 12 wherein said elongated support includes an automatic cab leveling device for maintaining said operator'"'"'s cab in a predetermined attitude regardless of the angular position of said boom assembly with respect to said pedestal.

15. The apparatus of claim 12 wherein said support tower is hollow to permit the passage of electrical wires, hydraulic lines, and deicing fluid lines therethrough.

16. The apparatus of claim 15 wherein said pedestal has an interior passageway formed therein to permit the passage of electrical wires, hydraulic lines, and deicing fluid lines therethrough.

17. The apparatus of claim 13 wherein a hydraulic motor is provided for rotating said operator'"'"'s cab with respect to said elongated support.

18. The apparatus of claim 12 wherein said operator'"'"'s cab is enclosed.

19. The apparatus of claim 12 wherein said boom assembly comprises an outer boom section having inner and outer ends, at least one intermediate boom section having inner and outer ends, and an inner boom section having inner and outer ends;

said inner end of said outer boom section being pivotally secured to said pedestal;

said inner end of said elongated support being pivotally secured to said outer end of said inner boom section.

20. The apparatus of claim 12 wherein said boom assembly includes a supporting means for supporting electrical wires, hydraulic fluid lines, and deicer fluid lines thereon.
