DUAL BOOM STRUCTURE, DUAL BOOM CRANE AND SHIP MOUNTED WITH THE SAME

Document Type and Number:

WIPO Patent Application WO/2011/043516

Kind Code:

A1

Abstract:

Disclosed is a dual boom structure including: a first trolley moving in the traverse direction along a first boom; a second boom connected to the first trolley to be supported thereby; a supporting joint connected to a point of the first trolley at a point of the second boom for supporting the second boom to be able to rotate; an auxiliary supporting die connected to another point of the first trolley at another point of the second boom and controllable in length; and a second trolley provided to the second boom and connected to a spreader, enabling the spreader to be raised or lowered. The crane mounted with the dual boom structure according to the present invention enables the control of the horizontal state or the position of the spreader in response to any one or more movements of heaving, rolling or pitching of the first boom according to the center support of the second boom by the supporting joint, the length control of the auxiliary supporting die and the length control of the cable.
