Abstract
Abstract A mobile machine of the kind having an elevatable and travelling load-supporting carrier comprising, a supporting base structure rotatable about a vertical axis, an articulated structure of pivotally interconnected booms having horizontal pivots and including a main boom and at least one auxiliary boom which main boom is pivotally supported by a horizontal pivot member mounted to a part of the supporting base structure and which one auxiliary boom or the auxiliary boom furthermost from the main boom is pivotally connected at its end remote from the boom interconnecting pivot to the load-supporting carrier.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
218 words
A mobile machine comprising a vehicle having a forwardly disposed cab for the driver and a rearwardly disposed body, a main boom having at its rear end a supporting base structure of such nature that it is swingably mounted on a generally vertical axis on the rear end of the body, means pivoting the main boom on said base structure so that in retracted position said main boom extends forwardly in the machine, an auxiliary boom pivotally mounted on the front end of the main boom, a load-supporting carrier pivotally mounted on said auxiliary boom, the pivot axes of said booms being parallel and extending transversely of the booms and the pivot axis between the booms being located forwardly on the machine when the main boom is substantially horizontal, means for swinging said main boom between a lower limit position where it extends below the horizontal at an acute angle to the horizontal and through the arc of more than 90* above the horizontal to an upper limit position, and mechanism including a fluid pressure thrust unit mounted on said main boom and connected by linkage to said auxiliary boom for angularly moving said auxiliary boom about its pivot on the main boom through an arc of at least about 180* in any position of the main boom.
Claim 2
Dependent Claim
218 words
A mobile machine comprising a vehicle having a forwardly disposed cab for the driver and a rearwardly disposed body, a main boom having at its rear end a supporting base structure of such nature that it is swingably mounted on a generally vertical axis on the rear end of the body, means pivoting the main boom on said base structure so that in retracted position said main boom extends forwardly in the machine, an auxiliary boom pivotally mounted on the front end of the main boom, a load-supporting carrier pivotally mounted on said auxiliary boom, the pivot axes of said booms being parallel and extending transversely of the booms and the pivot axis between the booms being located forwardly on the machine when the main boom is substantially horizontal, means for swinging said main boom between a lower limit position where it extends below the horizontal at an acute angle to the horizontal and through the arc of more than 90* above the horizontal to an upper limit position, and mechanism including a fluid pressure thrust unit mounted on said main boom and connected by linkage to said auxiliary boom for angularly moving said auxiliary boom about its pivot on the main boom through an arc of at least about 180* in any position of the main boom.
Claim 3
Dependent Claim
61 words
A mobile machine as claimed in claim 1, wherein said auxiliary boom is movable to a retracted position where it lies adjacently parallel to one side of said main boom, and means is provided in the connection between said booms to provide so that said auxiliary boom has an available total angle of swing of 360* relative to said main boom.
Claim 4
Dependent Claim
66 words
A mobile machine as claimed in claim 2, wherein the means for angularly moving said auxiliary boom about its pivot relative to the adjacent main boom is connected to said auxiliary boom through the intermediary of indexing means whereby the arc of angular movement of the auxiliary boom determined by the said means can be selectively displaced relative to the said adjacent boom in predetermined increments.
Claim 5
Dependent Claim
97 words
A mobile machine as claimed in claim 2, wherein the lengths of the main boom and the auxiliary boom are so related to one another and to the dimensional characteristics of the vehicle that when the articulated structure is in the retracted condition and the said auxiliary boom is in the angular movement quadrant between its retracted condition and a downwardly extended condition the load-supporting carrier which is pivotally attached thereto can be brought into coincidence with the entrance opening of the driver''s cabiN to provide a direct personnel transfer path between the cabin and the carrier.
Claim 6
Dependent Claim
27 words
A mobile machine as claimed in claim 4, wherein the load-supporting carrier is substantially wholly within the width of the vehicle when in the personnel transfer position.
Claim 7
Dependent Claim
37 words
A mobile machine as claimed in claim 1, wherein the pivot connecting the main boom to the supporting base structure is at a higher level than the roof of the cabin for the driver of the vehicle.
Claim 8
Dependent Claim
92 words
A mobile machine as claimed in claim 1, wherein a winch is mounted on the supporting base structure, and adjacent the transverse pivots of the articulated boom structure and the load-supporting carrier there are provided freely rotatable pulleys arranged to accommodate a lifting rope leading from the said winch to a crane hook below the said carrier or the movable end of the main boom to provide that the main boom can be used as a crane jib and the or the furthermost auxiliary boom can be used as a fly jib.
Claim 9
Dependent Claim
134 words
A mobile machine comprising a vehicle, a supporting base structure mounted on the vehicle roof for swinging about a vertical axis, a main boom having its rear end pivoted on said base structure, an auxiliary boom having its rear end pivoted on the front end of the main boom, a load carrier movably mounted on the auxiliary boom, the pivot axes of the booms being parallel and disposed transversely of said booms, and means disposed between the main and auxiliary booms for angularly swinging said auxiliary boom relative to said main boom, said means including indexing means for presetting the main and auxiliary booms at one of a predetermined number of angularly displaced positions from each of which said auxiliary boom may be swung through an arc of at least about 180* in operation.
Claim 10
Dependent Claim
134 words
A mobile machine comprising a vehicle, a supporting base structure mounted on the vehicle roof for swinging about a vertical axis, a main boom having its rear end pivoted on said base structure, an auxiliary boom having its rear end pivoted on the front end of the main boom, a load carrier movably mounted on the auxiliary boom, the pivot axes of the booms being parallel and disposed transversely of said booms, and means disposed between the main and auxiliary booms for angularly swinging said auxiliary boom relative to said main boom, said means including indexing means for presetting the main and auxiliary booms at one of a predetermined number of angularly displaced positions from each of which said auxiliary boom may be swung through an arc of at least about 180* in operation.
Claim 11
Dependent Claim
32 words
The mobile machine defined in claim 8, wherein said indexing means comprises an index member connectable at a predetermined number of angularly disposed positions to a thrust transmitting connection between the booms.
Claim 12
Dependent Claim
51 words
The mobile machine defined in claim 9, wherein said indexing member is a plate fixed to said auxiliary boom, a fluid pressure motor is mounted on the main boom, and said motor actuates a pivotal linkage connectable at any one of a predetermined number of angularly spaced points on said plate.
