Abstract: An articulated vehicle [10] has a first body section [12], a second body section [14], and an elongate projection [22] projecting from the first body section [12] towards the second body section [14]. A pair of steering cylinders [36, 34] are mounted such that they are partially or wholly disposed in or on the elongate projection [22], and are disposed one above the other so they overlap vertically, thereby narrowing the projection at the end nearer the first body section [12] and allowing the second body section [14] to be rotated closer to the centre line. A rotatable shaft [40] of the second body section [14] is mounted towards the far end of the elongate projection [22] and is steered by a pair of linkages such as chains [42, 44], each of which is connected to the shaft [40] and to a respective one of the steering cylinders [36, 34]. The chains [42, 44] wrap around the shaft [40] with a circumferential overlap, though they are spaced vertically.
