Integrated with the global advanced designing technology into our own experience, NGC R & D team has developed out the transmission solutions of dredgers, which can meet the developing requirements of large size and diversification. We are able to satisfy the requirement of equipment interface and whole-set performance according to performance and matching between the equipments.
Till today, we have developed out a series of transmission systems with NGC IP rights, such as submerged cutter gearbox, cabin dredge pump gearbox, submerged dredge pump gearbox, high pressure water pump gearbox, hydraulic pump gearbox, bucket wheel gearbox, pivot shaft gearbox, etc. and have been widely used in various types of dredgers.
