DESCRIPTION

(22) This disclosure is submitted in furtherance of the constitutional purposes of the U.S. Patent Laws to promote the progress of science and useful arts (Article 1, Section 8).

(23) The all-terrain construction vehicles and methods of the present disclosure will be described with reference to FIGS. 1-19.

(24) Referring first to FIG. 1, an all-terrain construction vehicle 10 is shown that includes a beam frame 12 that extends the length of the vehicle from the rear end of the vehicle to the front end of the vehicle. The length between the rear end of the frame and front end of the frame defines at least one axis. Frame 12 can be a box beam. Frame 12 can be a fabricated metal or structural steel frame, for example, and frame 12 may take on an I-beam configuration wherein the upper portions provide platforms and the lower portions provide platforms, and they may be connected by another member that is normal between both platforms. The frame can be a fabricated metal frame or structure. The frame can provide for platform mounting on top, bottom, and/or sides as well.

(25) Along this frame 12 can be wheels 14, and on opposing ends of frame 12 can be the levelers 16. While the levelers are depicted as two pairs, a single pair operatively associated with frame 12 may be sufficient for some applications. Upon the frame can be an open or enclosed operator cab 18, as well at the end of frame 12 can be a blade 20.

(26) The blade 20, levelers 16, and wheels 14 can all be manipulated via an engine, to be disclosed later, that also may drive hydraulics for the manipulation of the blade levelers and wheel angle, for example.

(27) Referring next to FIG. 2, a front view of all-terrain construction vehicle 10 is shown that includes a depiction of the extended levelers 16, wheels 14, and a muffler above hydraulic pump/engine 22 and cab 18. As can be seen, hydraulic pump/engine 22 is offset from cab 18 upon frame 12, for example. More particularly, engine 22 and cab 18 oppose one another with frame 12 therebetween. Therein, engine 22 is along one side of the axis and cab 18 is along the other side.

(28) Referring next to FIG. 3, according to one orientation, vehicle 10 may be upon a nonplanar surface, wherein perhaps front wheels 14 are offset from rear wheels 14. Wheels 14 can reside along an axle 30, and this axle 30 may also pivot upon frame 12, for example, allowing for the rotation of the axle wheel assembly as shown in FIG. 3. More particularly, vehicle 10 can include a pair of axles. One of the pair of axles 30 as shown can be associated with the front end of vehicle 10 and the other of the pair can be associated with the rear end of the vehicle. As shown, each of the axles can extend substantially normally across the one axis. By substantially normally, the axles may extend away from the axis at a functional angle. Either or both of the two axles may be configured to pivotably couple with frame 12 at a point such as shown at point 32 for example.

(29) Referring to FIG. 4, the wheel assembly and levelers can be aligned wherein axle 30 and axis point 32 are juxtaposed from rear wheels in the vehicle, and levelers 16 associated with the rear of the vehicle are aligned with the rear wheels, while the levelers in the front of the vehicle are aligned with the front wheels, thereby allowing for hillside leveling, according to an embodiment of the disclosure.

(30) In the box beam configuration, opposing opening through the walls of the box beam can be provided. Axle 30 can extend through these openings and pivotably couple.

(31) Various configurations of the axles and levelers of vehicle 10 are shown in FIG. 4A. The leveling can allow the chassis to be leveled completely plumb for stationary work when using a main attachment such as a man lift or digger derrick, for example. The axle leveling can allow for rough chassis leveling during travel to increase stability while traveling along a hillside.

(32) In accordance with example implementations, vehicle 10 may be equipped with auto leveling systems that provides for the auto leveling of vehicle 10 in the ambulatory or stationary configuration. As an example, when auto leveling is engaged, the electronic control system sends a signal to the rear axle leveling valve which will send hydraulic oil to the rear axle levelling cylinders keeping the machine level when stationary or moving. The front axle can float when auto level is engaged. Float refers to allowing the axle to tilt freely along axis 32. Vehicle 10 can include a front axle float mode where the rear axle is locked, and the front axle floats. Vehicle 10 can also be tilted manually where the operator tilts the machine manually which engages both the front and rear axles.

(33) Referring next to FIG. 5, a top view of vehicle 10 is shown wherein the blade 20, levelers 16, wheels 14, and pivot points 32 (part of the one axis) and axles 30 are aligned along frame 12 with cab 18 opposing engine 22.

(34) As shown, at least two pairs of wheels are provided, with each wheel of each pair operatively coupled to each end of each respective axle 30. Each of the wheels pivotably couple with each end of the axle and are configured to pivot in parallel with an opposing wheel as is depicted in FIGS. 6-9. The wheels may pivotably couple about another axis that is substantially normal to the axis of points 32. Each wheel includes an independent wheel drive having variable hydraulic motors. For example, Planetaries: Auburn 160CD triple reduction compact final drive and Danfoss H1 80 cc cartridge motor with speed sensing can be utilized as part of a rim that will support tires such as forestry tires that are 64 OD?24 wide.

(35) Referring to FIG. 6, according to one orientation, wheels 14 at the front of vehicle 10 are shown in a slightly turned position. Referring to FIG. 7, both front and rear wheels are turned in the same direction, allowing for independent turning of wheels 14 at hubs 60 and 62, for example. Referring to FIG. 8, again according to another orientation, wheels move independently of one another wherein front wheels are turned in one direction, and rear wheels are turned in the opposing direction.

(36) Referring to FIG. 9, a top view of the all-terrain construction vehicle of FIG. 1 is shown depicting additional components of the vehicle, for example, front and rear winches 70 and 80. Engine pump unit 72 can be a hydraulic fluid pump unit such as the Cummins QSB6.7L 260HP for example. This unit can provide for both hydraulic pumping to open and closed loop systems as well as electrical energy production for operable use of vehicle 10. Hydraulic fluid can be stored in tank 86 and a water tank 74 can be provided with an electric pump if desired. Dual hose reels 76 and tool boxes 78 can also be provided. A fuel tank 82 can be provided on the opposing side of the axis along with operator cab 84 which can be equipped with an air ride system. The vehicle may also be equipped with a roll over protection system.

(37) Unit 72 can be operatively coupled to the axles, wheels, blades, the levelers and/or attachments via hose and control valves as well as the operator interface control panel within the operator cab. The wheels may be coupled to a hydrostatic (closed loop) pump.

Digger derrick 90 can have a pole picker end 92 as well as a digging apparatus 94. Digger derrick 90 can be coupled to frame 12 at the rear end portion of construction vehicle 10, for example. This is just one example of an attachment for vehicle 10. As shown, these attachments couple with vehicle 10 at the rearward portion of the vehicle, but they also extend above the axis of the frame and between the pump unit and operators cab.

(41) Referring to FIG. 13, digger derrick 90 is shown in more detail alone, having pole picker end 92 and digger 94, for example. The digger derrick can include telescoping members, an auger, and a hook. In accordance with example implementations and with reference to FIG. 14, digger derrick 90 is shown in three positions; one in the stationary position, or traveling position; another in the pole picking position; and another in the digging position.

(42) Referring to FIG. 15, all-terrain construction vehicle 10 is shown with a man lift attachment, and this attachment as well is coupled to frame 12 at the rear portion. FIG. 16 depicts the man lift assembly as well separate from vehicle 10. As shown, the man lift assembly can include articulating members coupled to a man bucket.

(43) Referring next to FIG. 17, according to another embodiment of the disclosure, vehicle 10 can include at least two pairs of levelers 150, one pair associated with the rear end of vehicle 10 and another pair associated with the front end of vehicle 10. Each of the levelers 150 can include an arm 152 and a foot 154. Arm 152 can extend from the axis of 32 and can be configured to have one end of the arm pivotably couple to the frame about that axis. Arm 152 can extend substantially normally to the one axis according to an implementation. The arm can be configured and controllable to pivot between a first position 160 for stationary use and a second position 170 during ambulatory use or the travel position.

(44) In the travel position 170, foot 154 can be configured to support a utility pole for example. Foot 154 can be configured to pivotably coupled with arm 152 and can include a base 172 and a member 174 connecting the base with the arm.
