Knuckle boom cranes

Knuckle boom cranes are especially developed for use on different types of vessels. The crane appears similar to a standard offshore crane except that the boom mechanism articulates at the ‘knuckle’ near the middle so the crane is capable to control and lift the load in a more stable way, also during difficult conditions.

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

The Kenz knuckle boom crane is easy to customize in order to fit client requirements. As opposed to its contemporaries, our design has the main hoist rope running underneath the knuckle. With its “easy to re-reeve” main boom lift, the hoist rope can be placed over the main boom to handle taller and heavier loads. In addition to this, the main hoist winch can be placed below the deck (also at a later stage) which facilitates deeper operations and better vessel stability.

  • Boom length 18m to 45m
  • Maximum capacity 250t
  • Supplied in accordance with all international standards
  • Certified by all recognized authorities
