Abstract
A vehicle includes a chassis, a front axle coupled to a front end of the chassis, a rear axle coupled to a rear end of the chassis, a pair of front downriggers coupled to the front end of the chassis forward of the front axle, a pair of rear downriggers coupled to the rear end of the chassis rearward of the rear axle, and an outrigger assembly coupled to the chassis between the front axle and the rear axle. The pair of front downriggers is selectively extendable to engage a ground surface. The pair of rear downriggers is selectively extendable to engage the ground surface. The outrigger assembly includes a pair of outriggers that are selectively extendable laterally outward at an angle relative to a horizontal.
Claims19
A vehicle comprising:
- a chassis;
- a front axle coupled to a front end of the chassis;
- a rear axle coupled to a rear end of the chassis;
- and
- a stability system including:
- a pair of front downriggers coupled to the front end of the chassis forward of the front axle, the pair of front downriggers selectively extendable to engage a ground surface;
- and
- an outrigger assembly coupled to the chassis between the front axle and the rear axle, 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 first angle relative to a horizontal, and wherein at least one of (i) the first angle is a fixed angle or (ii) the foot is extendable at a second angle relative to the arm that is different than the first angle.
A vehicle comprising:
- a chassis;
- a front axle coupled to a front end of the chassis;
- a rear axle coupled to a rear end of the chassis;
- and
- a stability system including an outrigger assembly coupled to the chassis between the front axle and the rear axle, 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 first angle relative to a horizontal, and wherein at least one of (i) the first angle is a fixed angle or (ii) the foot is extendable at a second angle relative to the arm that is different than the first angle;
- an outrigger housing having a first tube and a second tube, wherein the first tube and the second tube extend laterally across the chassis, and wherein the first tube is oriented at the fixed angle with a positive slope and the second tube in oriented at the fixed angle with a negative slope;
- and
- a collar positioned to couple proximate ends of the first tube and the second tube together.
A vehicle comprising:
- a chassis;
- a front axle coupled to a front end of the chassis;
- a rear axle coupled to a rear end of the chassis;
- and
- a stability system including an outrigger assembly coupled to the chassis between the front axle and the rear axle, 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 first angle relative to a horizontal, and wherein at least one of (i) the first angle is a fixed angle or (ii) the foot is extendable at a second angle relative to the arm that is different than the first angle;
- a first housing tube having a first end and an opposing second end, the first housing tube extending laterally across the chassis along a positive slope;
- a second housing tube having a third end and an opposing fourth end, the second housing tube extending laterally across the chassis along a negative slope such that (i) the first end of the first housing tube and the third end of the second housing tube and (ii) the opposing second end of the first housing tube and the opposing fourth end of the second housing tube are vertically offset;
- and
- one or more collars positioned to couple at least one of (i) the first end of the first housing tube and the third end of the second housing tube or (ii) the opposing second end of the first housing tube and the opposing fourth end of the second housing tube together.
