Abstract
Abstract In accordance with an illustrative embodiment of the present invention, a mobile article handling vehicle adapted for off-theroad operations such as pipe laying in the most rugged types of terrain includes a light weight vehicle unit with ground engaging tires of great ground bearing area, a rotatable, upright mast on the unit, a tiltable boom with its inner end pivoted to the upper end of the mast, a hoist structure movable longitudinally along the boom between selected stations, and a supporting leg pivoted to the outer end of the boom and rotatable between a supporting position where the lower end thereof engages the ground to provide vertical support, and a traveling position substantially parallel to and above the boom.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
124 words
Apparatus for use in off-the-road hoisting operations, comprising: a vehicle unit having ground engaging means; an upright mast on said unit; boom means having one end pivotably attached to the said mast; hoist means movable longitudinally along said boom means and adapted for handling a load; support means pivotally attached to the other end of said boom means, said support means being adapted for pivotal rotation between a supporting position at right angles to said boom means where the lower end of said support means rests on the ground and provides vertical support, and a traveling position substantially parallel to and above said boom means; and selectively operable motor means for pivotally rotating said support means between said supporting position and said traveling position.
Claim 2
Dependent Claim
124 words
Apparatus for use in off-the-road hoisting operations, comprising: a vehicle unit having ground engaging means; an upright mast on said unit; boom means having one end pivotably attached to the said mast; hoist means movable longitudinally along said boom means and adapted for handling a load; support means pivotally attached to the other end of said boom means, said support means being adapted for pivotal rotation between a supporting position at right angles to said boom means where the lower end of said support means rests on the ground and provides vertical support, and a traveling position substantially parallel to and above said boom means; and selectively operable motor means for pivotally rotating said support means between said supporting position and said traveling position.
Claim 3
Dependent Claim
22 words
The apparatus of claim 1 further including means for tilting said boom means to various angles of inclination with respect to horizontal.
Claim 4
Dependent Claim
30 words
The apparatus of claim 1 wherein said hoist means includes an upper carriage assembly and a lower carriage assembly, said lower carriage assembly being movable transversely of said boom means.
Claim 5
Dependent Claim
39 words
The apparatus of claim 3 further including first selectively operable motor means for moving said hoist means longitudinally of said boom means and second selectively operable motor means for moving said second carriage means transversely of said boom means.
Claim 6
Dependent Claim
169 words
Apparatus for use in off-the-road hoisting operations, comprising: a mobile vehicle unit having ground engaging means; an upright mast on said unit; elongated boom means having one end pivoted to the upper end of said mast; means for rotating said mast and said boom means about a vertical axis to enable said boom means to be selectively disposed in a working position extending to the side of said unit and a traveling position aligned with the longitudinal axis of said unit; carriage means suspending an article handling device and being movable longitudinally along said boom means; support means pivoted to the other end of said boom means and adapted for pivotal rotation between a supporting position at right angles to said boom means where the lower end of said support means rests on the ground and provides vertical support, and a traveling position substantially parallel to and above said boom means; and selectively operable motor means for rotating said support means between said supporting position and said traveling position.
Claim 7
Dependent Claim
169 words
Apparatus for use in off-the-road hoisting operations, comprising: a mobile vehicle unit having ground engaging means; an upright mast on said unit; elongated boom means having one end pivoted to the upper end of said mast; means for rotating said mast and said boom means about a vertical axis to enable said boom means to be selectively disposed in a working position extending to the side of said unit and a traveling position aligned with the longitudinal axis of said unit; carriage means suspending an article handling device and being movable longitudinally along said boom means; support means pivoted to the other end of said boom means and adapted for pivotal rotation between a supporting position at right angles to said boom means where the lower end of said support means rests on the ground and provides vertical support, and a traveling position substantially parallel to and above said boom means; and selectively operable motor means for rotating said support means between said supporting position and said traveling position.
Claim 8
Dependent Claim
22 words
