Abstract

1432124 Jib assemblies POCLAIN 15 July 1974 [24 July 1973] 31202/74 Heading B8B [Also in Divisions E1 and F1] Potential energy is transferred between a jib 2, pivoted at 3 on a support 1, and an accumulator 16 through fluid passing via a duct 17 between a chamber 15a in an hydraulic jack 15 and the accumulator 16 as the jib 2 is luffed by conventional means (illustrated as an hydraulic jack 4). The jack 15 may be replaced by a jack having a rotary piston (not shown).
