Patented design
Our new boomerang shaped crane has wire/rope routed directly from winch to boom tip. This increases the work area compared to standard knuckle boom cranes and reduces wear and tear of wire. The crane is ideal for artic operations and fiber rope use.

Shipboard/Deck Cranes
SEAONICS also provide a wide selection of shipboard/deck cranes including Knuckle boom, fixed boom, telescopic and foldable cranes. Capacity range from SWL 0-25T and 2-25 m with options for remote control by cable or radio. Cranes are delivered as one unit to yard after FAT for easy installation.
