Abstract

An inclinable jib having a first beam with one end that is fixed to a lower king-pin to form a jib foot while the other end of the jib foot is pivotally connected to the base of a second beam which constitutes a jib head. A fixedly positioned winch is connected by means of a cable to the free end of the jib head to control the variations of inclination of the jib head and jib foot. A constant length sling has one end fastened to a fixed point while the other end is fastened to the jib foot with stop means in one embodiment being provided on the jib foot to make it mechanically integral with the jib head when the same is raised to a given position whereby the single winch may operate both jib foot and jib head in the selected manner. Various alternative embodiments including multiple arrangements of pulleys are provided to achieve the desired results.
