Abstract

1375217 Inclined-jib cranes MAGYAR HAJO ES DARUGYAR 18 Jan 1972 [19 Jan 1971] 2381/72 Heading B8B A jib crane, particularly for ship or dockside use, comprises an inclined jib along which can run a trolley 4 controlled by a trolley winch 23 and a cable 3. A load cable 2 runs from a load winch 1 over guide pulleys on the trolley 4, at the jib head 5 and at the load block 17, there being m falls of the load cable 2 at the block 17 and n falls at the jib head 5. The angle of inclination α of the jib is calculated from the formula α=arc sin(n - 1)/m to ensure horizontal load travel when the trolley 4 is moved with the load winch 1 inactive.
