  • Patent number: 8893905
    Abstract: A crane jib system having a main jib, an auxiliary jib, and a telescoping cylinder. The main jib is comprised of main telescoping portions and the auxiliary jib is attached to the main jib and comprises auxiliary telescoping portions. The telescoping cylinder has a first telescopic part locking unit disposed on a base portion of the telescoping cylinder. The first telescopic locking unit is adapted to selectively engage the main telescoping portions. A second telescopic part locking unit is disposed on the telescoping cylinder above the first telescopic part locking unit. The second telescopic part locking unit is adapted to selectively engage the auxiliary telescoping portions.
