ABSTRACT:
FIELD OF THE INVENTION
This invention relates to hydrant servicer carts, used in the refuelling of aircraft from pressurised underground mains accessed by hydrants at the loading/unloading aprons of airports.
OBJECT OF THE INVENTION
The invention seeks to meet the need for a servicer cart which can remain on the apron at a particular bay while being readily movable from one side of the aircraft to the other, and is capable of servicing the full range of aircraft which may use the bay at which it is stationed. Carts according to the preferred embodiments of the invention meet these requirements, while being readily maneuvered by a single operator, typically having self-propulsion for ordinary operating needs and being towable for maintenance.
DISCLOSURE OF THE INVENTION
There is disclosed herein an aircraft refuelling cart including:
a chassis having ground-engaging wheels,
a refuelling platform for supporting an aircraft refuelling person or persons and being mounted to the chassis,
means for raising and lowering the platform with respect to the chassis,
a hydrant hose having a coupler for connection to an airport fuel hydrant,
a fuel conveying boom which receives fuel from said hydrant hose, the boom being vertically extendable and retractable and capable of conveying said fuel, and
a fuel hose coupled to an upper end of said boom and receiving fuel therefrom, the hose including fuel delivery means accessible by an aircraft refuelling person upon the platform for attachment to an aircraft to convey fuel thereto.
Preferably, the refuelling platform is mounted to the chassis by means of one or more scissor-action mechanisms, each including a plurality of pivotally interconnected support members.
Preferably, the boom includes a plurality of rigid segments pivotally coupled end-to-end.
Preferably, each segment of the boom resides adjacent to and is substantially parallel and co-extensive with a respective one of said support members.
Alternatively, the support members of the or each scissor-action mechanism pivot about respective parallel pivot axes and each segment of the boom resides in a plane or planes which is/are substantially parallel to said pivot axes.
Preferably, the platform includes hand rails which are pivotally collapsible.
Preferably, the boom is partly supported by the platform.
Alternatively, the boom is independent of the platform, such a boom being independently operable, avoiding the need to maintain the platform at operating height throughout the refuelling process.
Carts as disclosed herein present a small footprint but are capable of refuelling the full range of high-wing aircraft currently in use at major airports.
