Abstract
In an implement-carrying telescopic boom structure an actuator for operating an implement carried on a beam 26 telescoping within a boom portion 20 is secured at 61 to a member 27 so mounted on the boom as to be slidable longitudinally thereof. Preferably the member and the beam are connected together adjacent the implement.
