• Product Description

    A knuckle boom crane appears similar to a standard craneexcept 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 manoeuvring.

    Knuckle boom cranes have become very common on offshore vessels as less of the deck space is blocked by the crane.

    The cranes come with different types of control systems, such as: stand up, control from the ground, seat control, or radio remote control. The radio remote systems now can start the crane as well as run the crane.

    The knuckle boom crane range is available from 0.5t to 150t lifting moment. Severe weather conditions and heavy seas introduce oscillating motions to suspend loads.

    Advantages for OUCO Marine/Offshore knuckle boom cranes are:

    Hydraulic type makes the crane maintain easily;

    Flexibility by extending booms;

    Smaller ones take very limited space on the vessel/ship/shipyard;

    Bigger ones can do heavy duty loads in several working conditions.

    The innovative design of the knuckle boom crane allows workers to perform great number of logistic tasks. The function of these heavy duty machines is to load and unload heavy materials from one location to another. Due to its durable construction technologies and precision, knuckle boom crane provides an extra solid hand to any workforce. With its great lifting power, payload space and maneuverability, knuckle boom crane successfully replaces manpower.
