A system to stabilize a construction vehicle is disclosed having a frame and a pair of stabilizing legs with ground-engaging shoes at the ends of the legs. The stabilizing legs may pivotally connect to the frame on substantially opposing sides, so that the stabilizing legs pivot upwards to a stowed position and pivot downwards to a stabilizing position where the shoe engages the ground. The stabilizing legs may telescope between a retracted and extended position. The retracted position locates the shoe closer to the vehicle and the extended position further from the vehicle. A pair of hydraulic cylinders may be connected to the respective stabilizing legs to power the telescopic movement of the stabilizing legs between the retracted position and extended position. A controller may allow substantially lateral movement of the construction vehicle while the pair of stabilizing legs are engaged with the ground to support the construction vehicle.
