Knuckleboom crane for offshore applications
max. 250 Mt | KBC
Huisman-Itrec
The Huisman Knuckleboom Crane (KBC) is specially designed for the use in an offshore environment. Its tasks vary from construction, pipe handling to subsea installation work. Huisman has experience in designing and building KBC's up to 250mt lifting capacity and 2,500m water depth. In addition we are constantly exploring new and heavier means of application.
The KBC consists like a regular Pedestal Crane of a crane house which is bolted via the slew bearing to the pedestal. The boom however consists of two parts. The main boom is hinged at the middle creating a knuckle boom. Both parts are controlled with hydraulic cylinders. This way, movements of the load can be limited as the boom tip can be kept at a limited height above deck. This feature makes the crane safe and efficient. The winches of a KBC are normally fitted outside the crane house since they require a large storage capacity for ultra deep lifts.
