Abstract:
1. A stabilized wheeled service vehicle comprising: a chassis; an extendable servicing equipment attached to an upper surface of said chassis via a rotatable turntable; a system of actuators for raising, lowering, extending and rotating a telescoping boom; and at least one pair of independently extendable outriggers, each outrigger of said pair mounted on a respective side of said chassis in an opposed relationship, each outrigger comprising a telescopic leg assembly comprising a first telescopic member and a second telescopic member slidably overlapping and extending outwardly from said first telescopic member along a longitudinal axis, an actuator housed within said telescopic leg assembly for slidably extending or retracting said first telescopic member versus said second telescopic member along said longitudinal axis, a footing at an outer end of said second telescopic member, a mounting bracket for connection to the chassis comprising an upper mounting point and a lower mounting point offset horizontally from said upper mounting point, a first flange extending from said first telescopic member and pivotally mounted to said upper mounting point at a point offset from said longitudinal axis and an elongate linkage pivotally attached between said lower horizontally offset mounting point and a pivot point on said second telescopic member; wherein when said telescopic leg is extended away from said chassis, a distance between said lower mounting point and said upper mounting point remains greater than a distance between said lower mounting point and said pivot point on said second telescopic member and said foot follows a path comprising an initial extending part comprising a horizontal component and no downward component followed by a subsequent ground engagement part wherein said foot engages the ground while moving downwards at an angle substantially normal to the ground.
