Abstract
1459568 Shovelling machines POCLAIN 13 June 1974 [28 June 1973] 26342/74 Heading E1F An excavator comprises a balance beam 1 and hydraulic jacks 12, 15 which are pivotally connected to a jib 2 by spindles 3, 13 and 16 respectively, a bucket casing 6 pivotally connected to the balance beam 1 and the hydraulic jack 12 by spindles 5 and 14 respectively, and a bucket base 7 pivotally connected to the casing 6 and to the hydraulic jack 15 by spindles 8 and 17, the distances between spindles 3 and 13, 3 and 16, and 13 and 16 being equal respectively to the distances between spindles 5 and 14, 5 and 17, and 14 and 17. A stop 9 is provided for limiting the pivotal movement of the base 7 relative to the casing 6. A hydraulic circuit for controlling jacks 12, 15 and 18 is described, (Fig. 3).
