FLOATING CRANE

摘要

PURPOSE: A floating crane is provided to ensure efficiency and stability of cargo-working since balance is maintained by a mass balance unit even under wave or wind. CONSTITUTION: A floating crane(1) comprises a crane structure(2), a floating body(3), and a mass balance unit. The trolley(6) of the crane structure moves in one direction. The floating body supports the crane structure on the water by buoyancy. The mass balance unit moves mass to maintain the balance of the crane.
