Abstract
969,727. Ships' derricks. J. & K. SMIT'S SCHEEPSWERVEN N.V. March 5, 1963 [March 5, 1962], No. 8663/63. Heading B8B. A derrick, Figs. 1 and 2, for turning the lateral suction tube of a dredger inboard and outboard comprises a pair of struts 1 luffably pivoted to a deck and a boom 4 universally mounted at 6 and connected to the upper ends of the struts by a spar 5. The suction tube 11 is raised by a cable 9 which passes over sheaves 7, 8, 10. A hook 13 locks the derrick in its inboard position. The derrick is luffed by the hoisting rope 9 and a guy 14 limits the outward swing thereof. Figs. 4-9 (not shown) illustrate successive stages in swinging out the tube 11 from its stowed position on saddles 12.
