Abstract A jib assembly is disclosed, for use with an articulated boom carried by an aerial device, having a compact configuration of components which allows a high degree of freedom in the rotation of the jib in the vertical plane and reduced obstruction of the rotational adjustment of the bucket carrier on the boom in the horizontal plane, relative to existing arrangements. A chain and sprocket arrangement driven by a hydraulic motor powers rotation of the jib coaxially with the bucket shaft and, where a winch is used, with the axis of rotation of the winch. The arrangement simplifies the routing of hydraulic hoses and affords a more compact and less cluttered arrangement of components at the tip of the boom, which has safety advantages in the environment of a tight distribution of power lines, where distances between live and grounded apparatus are small.
