Abstract

A system includes an outrigger assembly configured to be coupled to a chassis of the vehicle. The outrigger assembly includes a pair of outriggers. Each outrigger of the pair of outriggers includes an arm and a support foot. The arm is selectively extendable laterally outward at a fixed angle relative a horizontal.

First claim

The invention claimed is:

1. A system for a vehicle, the system comprising:
an outrigger assembly configured to be coupled to a chassis of the vehicle, the outrigger assembly including a pair of outriggers;
wherein each outrigger of the pair of outriggers includes an arm and a support foot;
wherein the arm is selectively extendable laterally outward at a fixed, downward sloping angle relative to a horizontal;
wherein the fixed, downward sloping angle is a first angle; and
wherein the support foot is extendable relative to the arm at a second angle that is different than the first angle.

2. The system of claim 1 , wherein the outrigger assembly includes an outrigger housing having a first tube and a second tube, wherein the first tube and the second tube are configured to extend laterally across the chassis, and wherein the first tube is oriented at the fixed, downward sloping angle with a positive slope and the second tube in oriented at the fixed, downward sloping angle with a negative slope.

3. The system of claim 2 , wherein the fixed, downward sloping angle is within a range of five to fifteen degrees below the horizontal.

4. A system for a vehicle, the system comprising:
an outrigger assembly configured to be coupled to a chassis of the vehicle, the outrigger assembly including a pair of outriggers;
wherein the outrigger assembly includes an outrigger housing having a first tube and a second tube;
wherein the first tube and the second tube are configured to extend laterally across the chassis;
wherein the first tube is oriented at the fixed, downward sloping angle with a positive slope and the second tube in oriented at the fixed, downward sloping angle with a negative slope;
wherein the outrigger housing includes a collar positioned to couple proximate ends of the first tube and the second tube together;
wherein each outrigger of the pair of outriggers includes an arm and a support foot;
wherein the arm is selectively extendable laterally outward at a fixed, downward sloping angle relative to a horizontal.

5. A system for a vehicle, the system comprising:
an outrigger assembly configured to be coupled to a chassis of the vehicle, the outrigger assembly including:
an outrigger housing having a first tube and a second tube, the first tube and the second tube configured to extend laterally across the chassis;
a pair of outriggers;
a first collar positioned to couple first proximate ends of the first tube and the second tube; and
a second collar positioned to couple opposing second proximate ends of the first tube and the second tube together.

6. The system of claim 4 , wherein the collar has a z-shaped structure.

7. A system for a vehicle, the system comprising:
an outrigger assembly configured to be coupled to a chassis of the vehicle, the outrigger assembly including a pair of outriggers, each outrigger of the pair of outriggers including an arm and a support foot, the arm is selectively extendable laterally outward at a fixed angle relative to a horizontal;
a first front downrigger configured to be coupled proximate a first lateral side of a front end of the chassis; and
a second front downrigger configured to be coupled proximate an opposing second lateral side of the front end of the chassis.

8. The system of claim 7 , further comprising a front bumper configured to be coupled to the front end of the chassis, wherein the first front downrigger is directly coupled to a first lateral end of the front bumper and the second front downrigger is directly coupled to an opposing second lateral end of the front bumper.

9. The system of claim 7 , further comprising:
a first bracket configured to couple the first front downrigger to a first frame rail of the chassis; and
a second bracket configured to couple the second front downrigger to a second frame rail of the chassis.

10. The system of claim 7 , wherein the first front downrigger and the second front downrigger are selectively pivotable laterally outward between a first position and a second position.

11. The system of claim 10 , further comprising
a first pivot actuator configured to facilitate pivoting the first front downrigger between the first position and the second position; and
a second pivot actuator configured to facilitate pivoting the second front downrigger between the first position and the second position.

12. The system of claim 10 , wherein the first front downrigger and the second front downrigger are configured to pivot from the first position to the second position to accommodate pivoting a cabin of the vehicle relative to the front end of the chassis.

13. A system for a vehicle, the system comprising:
an outrigger assembly configured to be coupled to a chassis of the vehicle, the outrigger assembly including a pair of outriggers; and
a pair of rear downriggers configured to be coupled to a rear end of the chassis;
wherein each outrigger of the pair of outriggers includes an arm and a support foot; and
wherein the arm is selectively extendable laterally outward at a fixed, downward sloping angle relative to a horizontal.
