Abstract
248,676. Naamlooze Vennootschap Werf Gusto voorheen Firma A. F. Smulders. April 21, 1925, [Convention date]. Jib cranes.-To ensure horizontal travel of the load in luffing, the load-rope a passes over a fixed pulley f, and over a headsheave b suspended from the jib head by a rope c which is unwrapped from a fixed sector i as the jib is raised.
