Abstract
1470077 Step-by-step Jacks MITSUI SHIPBUILDING & ENG CO Ltd 31 May 1974 [1 June 1973] 24580/74 Heading B8J Apparatus for raising and lowering a load I along a vertical column II includes a guide rail III disposed vertically along the periphery of the column II, an upper outer ring 1 vertically spaced from the lower outer ring 2, both surrounding the column II and provided with downwardly diverging inclined surfaces arranged to co-operate with respective wedges 3, 4 under the action of fluid-pressure cylinders 9, 10. Main raising and lowering fluid-pressure cylinders 17 act between the upper and lower rings 1, 2 in sequence with the cylinders 9, 10 to raise and lower the load I, suspended from the upper ring 1 by coupling bars 18, in step-by-step manner.
