Abstract
Abstract A container handling vehicle which may utilize a lift truck chassis with (a) telescoping means allowing the container handling devices to move parallel to the longitudinal axis of the chassis, (b) channel means allowing the container handling devices to move vertically, and (c) channel and roller means for allowing the vertical channels to move in a transverse direction, relative to the longitudinal axis of the vehicle. An alternate embodiment replaces stability producing outriggers with sets of hydraulically actuatable wheels, mounted at right angles to the vehicle main propulsion wheels, which hydraulically actuatable wheels produce improved stability of the vehicle.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
254 words
A load handling vehicle comprising a chassis, a frame mounted on the chassis, the frame comprising telescoping members extending longitudinally of the chassis and track members extending transversely of the chassis at the ends of the telescoping members, mast means mounted for transverse movement within the tracks, load handling arms mounted for vertical movement on the mast means, at least one outrigger means pivoted on the frame by means of pivot means, means on the outrigger means adapted to contact the surface upon which the vehicle is supported, said outrigger means being pivotable about a horizontal axis from an inoperative position substantially parallel to the vehicle frame to an operative position wherein said means on the outrigger means contacts the surface supporting the vehicle, track extension means mounted on said outrigger means and so located with respect thereto that said track extension means are brought into position in substantial alignment with the end of the track member when the outrigger means is extended to its operative position thereby providing an extension to the track member to enable the mast means to move beyond the end of the track member when picking up or setting down a load placed adjacent the vehicle, said outrigger means further being of a length and said pivot being so located whereby said means on said outrigger means acts as a vehicle fulcrum intermediate the vehicle and a load laterally adjacent the vehicle, and further including means for moving the outrigger means from and to its operative and inoperative positions.
Claim 2
Dependent Claim
254 words
A load handling vehicle comprising a chassis, a frame mounted on the chassis, the frame comprising telescoping members extending longitudinally of the chassis and track members extending transversely of the chassis at the ends of the telescoping members, mast means mounted for transverse movement within the tracks, load handling arms mounted for vertical movement on the mast means, at least one outrigger means pivoted on the frame by means of pivot means, means on the outrigger means adapted to contact the surface upon which the vehicle is supported, said outrigger means being pivotable about a horizontal axis from an inoperative position substantially parallel to the vehicle frame to an operative position wherein said means on the outrigger means contacts the surface supporting the vehicle, track extension means mounted on said outrigger means and so located with respect thereto that said track extension means are brought into position in substantial alignment with the end of the track member when the outrigger means is extended to its operative position thereby providing an extension to the track member to enable the mast means to move beyond the end of the track member when picking up or setting down a load placed adjacent the vehicle, said outrigger means further being of a length and said pivot being so located whereby said means on said outrigger means acts as a vehicle fulcrum intermediate the vehicle and a load laterally adjacent the vehicle, and further including means for moving the outrigger means from and to its operative and inoperative positions.
Claim 3
Dependent Claim
30 words
The vehicle of claim 1 wherein said means on the outrigger means adapted to engage the surface upon which the vehicle is supported comprise wheel means mounted on the outrigger.
Claim 4
Dependent Claim
35 words
The vehicle of claim 1 wherein the pivot means is located adjacent the end of a track member whereby the outrigger means is located directly below the track member when in a normal inoperative position.
Claim 5
Dependent Claim
38 words
The vehicle of claim 1 wherein said outrigger means is pivotally attached about a horizontal axis adjacent an end of a track and is located below and substantially parallel to said track when in a normal inoperative position.
Claim 6
Dependent Claim
21 words
The vehicle of claim 1 further including means on the load handling arms for gripping containers within standard fixtures located therein.
Claim 7
Dependent Claim
45 words
The vehicle of claim 1 further including means extending from the mast means to pivotally support the load handling arms, and stabilizing means extending between said load handling arms and said means extending from the mast means to stabilize the load carried by the arms.
Claim 8
Dependent Claim
22 words
The vehicle of claim 6 wherein the stabilizing means comprise hydraulic cylinder means pivotally connected between the members between which it extends.
Claim 9
Dependent Claim
182 words
A load handling vehicle comprising a chassis, a frame mounted on the chassis, the frame comprising telescoping members extending longitudinally of the chassis and track members extending transversely of the chassis at the ends of the telescoping members, mast means mounted for transverse movement within the tracks, load handling arms mounted for vertical movement on the mast means, means extending from the mast means to pivotally support the load handling arms, stabilizing means extending between said load handling arms and said mast means to stabilize the load carried by the arms, means on said load handling arms for gripping a load, at least one outrigger means pivoted on the frame by means of pivot means, means on the outrigger means adapted to contact the vehicle supporting surface which the vehicle is supported, said outrigger means being pivotable about a horizontal axis from an inoperative position substantially parallel to and beneath the vehicle frame to an operative position wherein said means on the outrigger means contacts the vehicle supporting surface, and means to move said outrigger means between its operative and inoperative positions.
Claim 10
Dependent Claim
182 words
A load handling vehicle comprising a chassis, a frame mounted on the chassis, the frame comprising telescoping members extending longitudinally of the chassis and track members extending transversely of the chassis at the ends of the telescoping members, mast means mounted for transverse movement within the tracks, load handling arms mounted for vertical movement on the mast means, means extending from the mast means to pivotally support the load handling arms, stabilizing means extending between said load handling arms and said mast means to stabilize the load carried by the arms, means on said load handling arms for gripping a load, at least one outrigger means pivoted on the frame by means of pivot means, means on the outrigger means adapted to contact the vehicle supporting surface which the vehicle is supported, said outrigger means being pivotable about a horizontal axis from an inoperative position substantially parallel to and beneath the vehicle frame to an operative position wherein said means on the outrigger means contacts the vehicle supporting surface, and means to move said outrigger means between its operative and inoperative positions.
