Product Description

Knuckle boom 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 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.
