<p>Handling apparatus of the type that includes a hydraulically actuated boom (18) or jib (18) has a support structure (14) carrying a boom pivot (28) to which a main boom (18) is pivoted. The boom actuator (24) is carried by a linkage (42) which is coupled to an additional actuator (48), this actuator (48) and the linkage (42) being pivoted on the fixed structure (14). The additional actuator (48) displaces the boom actuator (24) bodily as the boom (18) is raised and lowered. The invention is applicable especially to small excavators.</p> |
