Pedestal Mounted Cranes

Huisman delivers a large range of Pedestal Cranes which can be used for various tasks including unloading of supply vessels, pipe transfer and deck and subsea lifts: Pedestal Mounted (Offshore) Cranes and Knuckle Boom Cranes.


The boom of a Pedestal Mounted Crane is suspended from a boom hoist tackle, which runs from the top of the crane house to the head of the boom, and pivot hinges on the front of the crane house. With the boom hoist tackle the working radius of the lower blocks is controlled. The boom of a Knuckle Boom Crane is suspended from Hydraulic cylinders and pivot hinges on the front of the crane house.

 

The Huisman Pedestal Cranes comprise the following parts:

 

Slew bearing and Pedestal

The pedestal beneath the slew bearing can be equally supplied by Huisman. The slew bearing can be equipped with Eddy Current and/or a mechanical retainer ring preventing critical damage to the crane's structure.

 

Crane House

The crane house is installed via a slew bearing on top of the pedestal which is fixed to the vessel structure. It is a Huisman design philosophy to place all main equipment, like the main and boom hoist winches, electronic cabinets and hydraulic power units, inside the crane house protecting it from the corrosive marine environment. The operators cabin is mounted at a side of the crane house.

 

Boom

The boom is normally made as a lattice construction. In case of short boom lengths or high capacity, an A-frame construction, consisting of boxgirders, can be applied. On top of the boom a fly-jib can be provided to accommodate the whip hoist.

 

Winches

Winches are normally fitted inside the crane house, however different arrangements as for instance the location of winches in the hull or inside the jib structure can be provided as well. The winches of Knuckleboom Cranes are normally fitted outside the crane house as they require a large storage capacity for ultra deep water lifts. The final winch arrangement depends on the requirements and on the type of drive system selected.
