Floating cranes

Floating cranes are used in ports and in open waters for loading, discharging, transshipment and lightening (for ports with insufficient depth). Verstegen grabs operate on floating cranes from 16 to 63 ton.

Independent flexible operation

Floating grab cranes have been in operation for many years. Mounted on a (self-propelled) pontoon the cranes provide fast, independent operations. In ports or at open sea the cranes are used for loading, discharging, transshipment and lightening (for ports with insufficient depth). Often multiple floating cranes operate simultaneously on one vessel so very high unloading rates can be achieved.

 Lemniscate crane

The design of the Lemniscate crane is based on the double-boom principle, which delivers an optimal balance between weight and center of gravity. The cranes have short cycle times and offer a perfect view for the crane driver, direct on top of his work. Floating Lemniscate cranes are available in capacities from 16 to 50 ton and operate mainly in the Port of Rotterdam and Amsterdam.

 Harbour Pontoon crane

Manufacturers of mobile harbour cranes also offer floating cranes. These cranes use the same standardised concept as the standard rail or rubber tire-mounted mobile harbour cranes. The cranes have higher capacities up to 63 ton. Large stevedoring companies on the Mississippi river use these cranes for their operation.

 Crane Barge

Crane barges are mainly used for offshore transshipment operations. Most crane barges work with one or two 30-35 ton deck cranes on an outreach of 32 to 36 meters. These floating transfer stations (FTS) are especially popular in Indonesia for loading of coal.
