Abstract

Abstract The disclosure relates to means for transporting a landed helicopter on the deck of a ship at sea. A probe on the helicopter is grasped in a trap device mounted on a turntable provided on the deck of the ship. A dolly device is then moved into position and the helicopter clamped to it. The dolly device is guided by suitable rails so that, once the helicopter is clamped to it and unclamped from the trap device, the helicopter under full restraint can be moved along the deck to a parking space.

Dependent Claim 139 words
Means arranged and adapted for the conveyance of a helicopter on the deck of a ship, comprising: a. a load carrier; b. guide means fixed in relation to a deck of the ship; the guide means being adapted to restrain and to guide the load carrier and to position the load carrier under the helicopter after the helicopter has landed; c. a central member provided on the underside of the helicopter; d. anchor means carried by the load carrier; and e. operating means whereby the anchor means can be operated partially to embrace that central member to anchor the helicopter relative to the load carrier; whereby in use the landed helicopter is first secured to the load carrier, and the helicopter is then moved bodily about the deck by the load carrier under the guidance of the guide means.
Claim 3
Dependent Claim 60 words
Means for the conveyance of a helicopter according to claim 1, and in which: a. a guide rail constitutes the guide meaNs; and b. wheels are provided on the load carrier, these wheels being arranged to engage the guide rail and to locate the load carrier relative to the guide rail against all movements except movements along the guide rail.
Claim 4
Dependent Claim 68 words
Means for the conveyance of a helicopter according to claim 2, and in which: a. the guide rail is in the form of a metal strip shaped on opposite sides to form two guide tracks; and b. the said wheels include a plurality of wheels arranged to engage a first of the guide tracks, and at least one wheel arranged to engage the second of the guide tracks.
Claim 5
Dependent Claim 51 words
Means for the conveyance of a helicopter according to claim 1, and in which: a. the helicopter carrier is arranged to guide the load; and b. the weight of the helicopter is transferred directly to the said deck or to members, other than the load carrier, carried by the said deck.
Claim 6
Dependent Claim 29 words
Means for the conveyance of a helicopter according to claim 1, and in which: the helicopter carrier is arranged both to guide the load and to carry its weight.
Claim 7
Dependent Claim 125 words
Means for the conveyance of a helicopter according to claim 1, and in which: a. the load carrier is arranged both to guide the helicopter and to carry the weight of the helicopter; b. a first part of the load carrier is acted on by the guide means; c. a second part of the load carrier is connected to the first part in a manner ensuring that most of the weight of the helicopter will not be transferred to the guide means; and d. the said second part is provided with wheels by which the weight of the helicopter is at least for the most part carried by the deck of the ship and not by the said first part and by the guide means.
Claim 8
Dependent Claim 179 words
Means for the conveyance of a helicopter according to claim 1, and in which: a. the load carrier is arranged both to guide the helicopter and to carry the weight of the helicopter; b. a first part of the load carrier is acted on by the guide means; c. a second part of the load carrier is connected to the first part in a manner ensuring that most of the weight of the helicopter will not be transferred to the guide means; d. the said second part is provided with wheels by which the weight of the helicopter is at least for the most part carried by the deck of the ship and not by the said first part and by the guide means; e. the second part of the load carrier is arranged for movement axially of the guide means to a position in which it can assume the weight of the helicopter; and f. jack means provided on the said second part by which the weight of the helicopter can be assumed by the said second part.
Claim 9
Dependent Claim 62 words
Means for the conveyance of a helicopter according to claim 1, and in which: a. wheels are provided on the load carrier and engage a deck of the ship to carry the weight of the helicopter; and b. jack means provided on the helicopter carrier are operable to transfer the weight of the load from the deck to the wheeled load carrier.
Claim 10
Dependent Claim 42 words
Means for the conveyance of a helicopter according to claim 8, and in which: a. the jack means are hydraulic jacks; and b. a complete hydraulic system for the raising and lowering of the said jacks is carried by the load carrier.
Claim 11
Dependent Claim 68 words
Means for the conveyance of a helicopter according to claim 1, and in which: a. the central member is a probe carried by the helicopter; b. a trap device carried by the ship is arranged to seize and secure the probe when the helicopter lands; and c. the trap device is arranged to release the probe only when the helicopter has been secured to the wheeled load carrier.
Claim 12
Dependent Claim 76 words
Means for the conveyance of a helicopter according to claim 10, and in which: a. skid-type landing gear is provided on the helicopter; b. a turntable on the deck of the ship carries the trap device; c. the wheeled load carrier is movable between the skids into position to engage the probe after the turntable has been turned to bring the skids of the landing gear into paraLlelism with a longitudinal axis of the guide means.
Claim 13
Dependent Claim 68 words
Means for the conveyance of a helicopter according to claim 1, and in which: a. the load carrier is arranged to move axially of the guide means into proper relationship to the helicopter; b. a central member is provided on the helicopter; c. the anchor means are arranged to move laterally of the guide means to anchor the said central member of the helicopter to the load carrier.
Claim 14
Dependent Claim 74 words
