For hydraulic drives located close to water high demands according to reliability, corrosion protection or environmental compatibility have to be kept. These demands can be fulfilled by using modern piston rod coatings like the Ceraplate coating, by using special Hunger seal and guiding elements for environment friendly hydraulic fluids or by using maintenance free spherical bearings in stainless steel quality.

For the fishing harbour ship lock in Wilhelmshaven the complete hydraulic drive system was developed and built by the Hunger Group. Beside the hydraulic cylinders, manifold blocks and power packs with electric control also the installation and commisioning was part of our service.
