Extendable lattice type crane boom () for a crane (), the boom comprising a lattice type base boom section () and at least one lattice type telescopic boom section (), wherein the at least one telescopic boom section is adjustable with respect to the base boom section between a retracted position, in which the telescopic boom section is substantially inside of the base boom section, and an extended position, in which the telescopic boom section is at least partly outside of the base boom section, wherein a distal end of the base boom section to which a first guiding system () is mounted, the guiding system being configured to guide a movement of the telescopic boom section along the base boom section; wherein a proximal end of the telescopic boom section comprises a second guiding system () configured to guide a movement of the telescopic boom section along the base boom section.

Extendable lattice type crane boom, and method for operating a crane including an extendable boom

Drilling installation comprising a cantilever with a drilling floor for performing drilling operations; further comprising an independent operations handling system arranged for handling equipment underneath the drilling floor independent of the drilling operations on the drilling floor, wherein the independent operations handling system comprises a handling element for cooperation with the equipment to be handled, wherein the handling element is extendible underneath the cantilever.

Drilling installation: handling system, method for independent operations

Telescopic lattice type crane boom for a crane, further comprising a locking system configured to lock at least one telescopic boom section with respect to a base boom section in at least an extended position, wherein said locking system includes a plurality of pins, each pin being configured to extend, in at least the extended position of the boom, at least partly through a corresponding pin receiving aperture provided in one of the base boom section and the at least one telescopic boom section.
