Aquaculture Cranes

Our aquaculture cranes have been used in this industry for over 20 years. Designed specifically for this application, the cranes are robust, marinized, and not truck cranes.

With thicker pins and plates, they are built for operating in salt water and corrosive environments.

DMW Marine Cranes can be found on all of these modern OFFSHORE RIGS, plus many others: Transocean, Rowan and Noble. Now with ABS, API and DNV approvals, DMW Marine Cranes are becoming the standard of the industry.

Our telescoping and knuckle boom cranes are particularly well suited to offshore applications.
