A stabilizer assembly for laterally supporting a construction vehicle of the type having a material handling implement. The preferred embodiments of the stabilizer assembly permit selective positioning of the outboard ends of the stabilizer arms over a wide range of positions from a position immediately adjacent the vehicle wheels and near the longitudinal center line of the vehicle frame to a position substantially outside of the wheels and farther from the longitudinal center line of the vehicle frame. The inboard ends of the stabilizer arms are pivotally secured to a stabilizer anchor which is transversely slidable relative to the vehicle frame on either side of the center line thereof. Various means are disclosed for positioning of the stabilizer anchor relative to the vehicle frame and for retaining the stabilizer anchor in such position.

In a mobile heavy vehicle having a frame with a load lifting boom, an improved stabilizer assembly having a pair of stabilizers positioned one on each side of the vehicle to provide stabilization against tipping of the vehicle comprising: an anchor for stabilizing each of said stabilizers, means mounting each of said anchors to a lower portion of said frame so as to permit selective transverse positioning thereof on either side of the longitudinal center line of the vehicle including cooperating slot means defined by said frame and retaining means for positively positioning each anchor relative to the frame in a preselected position on either side of said longitudinal center line; first and second stabilizer legs having inboard ends which are pivotally secured to its respective stabilizer anchor and outboard ends which are respectively pivotally secured to first and second stabilizer pads; first and second stabilizer cylinders having first ends which are pivotally secured to upper portions of said frame, one on each side of said longitudinal center line, and second ends which are respectively pivotally secured to said first and second stabilizer legs for selectively moving the outboard ends of said stabilizer legs between raised and lowered positions, wherein said transverse positioning of said stabilizer anchors permits positioning of said first and second stabilizer pads between a retracted position nearer said longitudinal center line and an extended position farther from said longitudinal center line. In a mobile heavy vehicle having a frame with a load lifting boom, an improved stabilizer assembly having a pair of stabilizers positioned one on each side of the vehicle to provide stabilization against tipping of the vehicle; comprising: a stabilizer anchor slidably mounted on a transverse rail member secured to a lower portion of said frame so as to permit selective transverse positioning thereof on either side of the longitudinal center line of the vehicle; first and second stabilizer legs having inboard ends which are pivotally secured to said stabilizer anchor and outboard ends which are respectively pivotally secured to first and second stabilizer pads; first and second stabilizer cylinders having first ends which are pivotally secured to upper portions of said frame, one on each side of said longitudinal center line, and second ends which are respectively pivotally secured to said first and second stabilizer legs for selectively moving the outboard ends of said stabilizer legs between raised and lowered positions; and retaining means including a hydraulic clamp means including a clamp piston associated with said stabilizer anchor for clamping the stabilizer anchor to said rail member for selectively retaining said stabilizer anchor in a preselected position on either side of said longitudinal center line, wherein said transverse positioning of said stabilizer anchor permits positioning of said first and second stabilizer pads between a retracted position nearer said longitudinal center line and an extended position farther from said longitudinal center line.
