Trailer The dredge is transported on a specifically designed road trailer. This is designed to meet road transport regulation, but also to keep the dredge in one piece, thereby saving on mobilization time and cost. Reliability is also enhanced when hydraulic, electrical and other connections are not disrupted. The dredge is however fully demountable if a project should require this. The trailer is designed to act as a slipway for the dredge to place it in and out of the water. Hydraulic jacking legs provide for angling and a large hydraulic winch pulls the dredge on or off the trailer.
