DEC KNUCKLE BOOM CRANE
DEC Knuckle Boom Cranes are designed to provide maximum flexibility, extended outreach, and precise load handling, making them ideal for offshore, marine and wind industry applications. With their articulated boom design, these cranes allow for precise lifting and positioning, even in confined spaces. Additionally, the knuckle boom design reduces wire pendulum, minimizing the risk of damage caused by swinging loads. Compared to a traditional luffing jib crane with the same outreach, a knuckle boom crane requires significantly less stowing space, making it a more compact and efficient solutions.
MARINE APPLICATIONS
DEC KNUCKLE BOOM CRANES are widely used in the marine industry due to their flexibility and high lifting capacity. The knuckle boom design allows for precise lifting and positioning, making them ideal for confined dec spaces
Typical Marine Aplications:
✔ Service Cranes
✔ Provision Cranes
✔ Container and General Cargo Handling
OFFSHORE APPLICATIONS
For offshore enviroments, DEC KNUCKLE BOOM CRANES are engineered to perform in extreme conditions, ensuring high-performance lifting and handling. The knuckle boom allows for safe and controlled load movement, even in rough sea conditions.
Typical Offshore Aplications:
✔ Shipboard Cranes–Installed on vessels for multi-purpose lifting tasks
✔ Ship-to-ship Cranes–Designed for secure and efficient cargo transfer between vessels
✔ Provision Cranes–Used for lifting and handling supplies on offshore platforms
WIND INDUSTRY APPLICATIONS
DEC KNUCKLE BOOM CRANES are extensively used in the wind industry to support offshore wind farms,particularly for unloading supply vessels and handling materials on Trasition Pieces(TP) and offshore platforms. The knuckle boom design allows for precise and stable lifting, even in high sea states.
