Abstract
Abstract Wheeled vehicle with body including forward and rear upright support members in superposed relation to wheels and associated lift mechanism mounted on at least one of said members. One upright member movable forwardly and rearwardly on body to dispose associated lift mechanism in different working positions including a cradled seating position for the load on the body in superposed relation to the wheels, thereby permitting rapid transport of cradled load in balanced relation on vehicle, and a counterbalancing of vehicle weight to load when raising or lowering load. Also disclosed is a wheeled vehicle having an extendible load cradling structure. This vehicle includes a lift mechanism for lifting a heavy object from a ground support and the load cradling structure is selectively extendible to a position for receiving the lifted heavy object.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
257 words
Load lifting and transporting apparatus, comprising: a vehicle having a frame; first and second support members mounted on said frame in superposed relation thereto, said first support member being mounted on said frame for independent movement to different work positions toward and away from said second support member; a boom supported by each of said support members and mounted for conjoint movement with said first support member from one operating position where it is located almost entirely within the vertical plane of the vehicle to a second operating position where a portion of the boom extends beyond the vertical plane of the vehicle whereby whenever an object is lifted by the boom said first and second support members jointly support said object over said frame, and hold said object when elevated above the frame within the vertical plane of said vehicle during transport movement of the vehicle; and selectively operable lift means mounted on said first and second support members, for directing raise and lower movements to said boom said lift means being selectively operable to lift an object within a range from a rest position on the surface over which said vehicle travels to an elevated position higher than said frame, and said lift means being reversible so as to lower said object from said elevated position to an at rest position on the frame whereby selectively operating said lift means and moving said first support member toward and away from said second support member said object may be loaded on said frame or unloaded therefrom.
Claim 2
Dependent Claim
257 words
Load lifting and transporting apparatus, comprising: a vehicle having a frame; first and second support members mounted on said frame in superposed relation thereto, said first support member being mounted on said frame for independent movement to different work positions toward and away from said second support member; a boom supported by each of said support members and mounted for conjoint movement with said first support member from one operating position where it is located almost entirely within the vertical plane of the vehicle to a second operating position where a portion of the boom extends beyond the vertical plane of the vehicle whereby whenever an object is lifted by the boom said first and second support members jointly support said object over said frame, and hold said object when elevated above the frame within the vertical plane of said vehicle during transport movement of the vehicle; and selectively operable lift means mounted on said first and second support members, for directing raise and lower movements to said boom said lift means being selectively operable to lift an object within a range from a rest position on the surface over which said vehicle travels to an elevated position higher than said frame, and said lift means being reversible so as to lower said object from said elevated position to an at rest position on the frame whereby selectively operating said lift means and moving said first support member toward and away from said second support member said object may be loaded on said frame or unloaded therefrom.
Claim 3
Dependent Claim
31 words
Apparatus as defined in claim 1, in which said boom is slidable on a supporting surface of said second support member when it is moving conjointly with said first support member.
Claim 4
Dependent Claim
22 words
The invention recited in claim 1, including cradle means mounted on said frame for securing and supporting said object when loaded thereon.
Claim 5
Dependent Claim
33 words
The invention recited in claim 3, wherein said cradle means includes spaced object supporting surfaces between which said first support member travels in its movement toward and away from the second support member.
Claim 6
Dependent Claim
27 words
The invention recited in claim 1, wherein the movement of said first support means and said lift means is controlled by a hydraulic system on the vehicle.
