Abstract

A Public Works machine includes a jib on which is pivotally mounted a balance beam carrying a bucket comprising a casing on which is pivoted a base, a pair of hydraulic jacks being coupled between the support and casing and the support and base respectively for controlling operation of the bucket, the balance beam and hydraulic jacks forming opposite parallel sides of three parallelograms.
