Offshore crane
Knuckle boom crane with active heave compensation
A knuckle boom crane for offshore supply, construction and wind service vessels. The active heave compensation (AHC) system pays wire in and out against the vessel's vertical motion, so the load stays still while the ship moves.
- Safe working load
- 25 t at 15 m
- Capacity range
- SWL 1–50 t
- Main boom
- 18.4 m
- Knuckle + telescope
- 14.2 m + 4.2 m
- Max outreach
- 35 m
- Hydraulic pressure
- 250 bar
- Heave compensation
- Active, ±2.4 m/s rope speed
- Tilting moment
- Up to 10,000 kNm
Features
- Active heave compensation with accumulators and live heave readout
- Main boom, knuckle, telescope and winch on proportional control
- Load cell with SWL-at-radius indication and overload alarm
- Operator cabin or remote panel; start-up sequence with interlocks
- Sea-state derating for lifts from vessel to platform

- Two proportional joysticks
- Construction
- Pedestal, slew ring, hydraulic cylinders, bolts
Features
- Tip control mode moves the boom tip in straight lines, radially and vertically
- Transport lock and fold & stow sequence for sea passages
- Load moment indicator with wave-height derating
- Hook rotation and winch on the same console
- Marine coating and stainless fittings available for yachts

- 2 × hydraulic gearmotor
- Transport height
- 3.35 m above pedestal base
- Control
- Local valve bank or RF remote
- Winch
- Hydraulic hook winch
- Stowage
- Folded over the deck
Features
- Belly-box radio remote lets the operator work from the deck
- Platform valve bank with proportional levers
- Automatic fold and unfold sequences
- Overload logic set from the certified load chart
- Low transport height behind the wheelhouse
05 / 06 Tankers · Bunker vessels
Hose crane
Stiff boom crane for hose handling and provisions
A single stiff boom for lifting cargo and bunker hoses to the manifold and taking stores on board. Simple structure, few moving parts and a long life in tanker service.
- Capacity range

How to choose a marine crane
The right marine crane depends on the vessel, the heaviest load, the radius and the free deck space. Offshore vessels need heave-compensated knuckle boom cranes, fishing vessels prefer foldable cranes, tankers use stiff boom hose cranes and bulk carriers handle hatch covers with gantry cranes.
Tell us the vessel type, SWL and outreach and we propose the marine crane that fits, with a preliminary load chart.
Marine crane engineering and testing
Every marine crane is modelled in 3D, verified with finite element analysis and load tested before delivery. We design and test every crane to the rules of the vessel’s classification society, such as DNV, Lloyd’s Register or Türk Loydu. On request, the crane is delivered with class approval and a certificate from the classification society the customer chooses.
