Ship Hydraulic Knuckle Boom Marine Deck Crane CCS Approved

OUCO certifications

Knuckle boom cranes are designed to lift high loads with the jib extended and to provide the operator with great flexibility during lifting operations. Among other functions, they are used for pipe and boat handling. Thanks to their outstanding flexibility in radius, our knuckle boom cranes make it easy and safe to load and unload vessels and handle different materials.
The improved level of control makes the crane ideal for offshore lifting operations in higher sea states.

OUCO Knuckle boom marine crane appears similar to a standard crane, except that the boom articulates at the ‘knuckle near the middle, letting it fold back like a finger. This provides a compact size for storage and maneuvering.

The crane is controlled from an open platform above the slewing ring. One motion each (hoisting, slewing, or luffing) can be done with a full load. Each hydraulic circuit is provided with equipment for limiting hydraulic pressure to preset values corresponding with crane capacity. The crane is provided with an automatic hook stop in the top position. Overload safety device. Luffing up-down. The luffing cylinder is designed for safe buffering in extreme positions.

Consist of knuckle boom marine cranes: Pedestal, slewing ring, column, operation platform, winch, boom, pulley, wire rope, hook, etc.
