| 20110142590 | MODULAR HEAVY LIFT SYSTEM - A single heavy lift system is made of modular units, each of which has a pair of supporting legs carrying a transverse beam therebetween. The beam is engaged to the supporting legs through jackup units that allow the transverse beams of several modular units move in unison and thus increase lifting capacity of the system. The modular units can be formed as modular, self-propelled units, transported to the site, where the lifting task is to be performed if necessary. The system can be positioned in a dry dock or offshore. | 06-16-2011 |
