About Hydraulikpoint DAM GmbH
Hydraulikpoint DAM GmbH is a medium-sized, family-run company from Lüneburg near Hamburg with a branch in Ruhner Berge (district of Marnitz) between Hamburg and Berlin. The company manufactures and repairs hydraulic and pneumatic cylinders, designs and builds hydraulic power units from small to large units, and manufactures valve blocks in steel or high-strength aluminium, on request fully assembled and tested. In addition, the company offers mechanical engineering and contract machining in CNC and conventional milling, turning, drilling, welding and grinding – from single parts to small series. A focus is on components for wind turbines such as pitch and tip cylinders, bladder accumulators and hose assemblies for renowned operators and service providers. Further industries include shipping/maritime, aviation, mechanical engineering, plant engineering and the leisure business. The portfolio is rounded off by hose assembly, pipe bending, mobile tampon plating, maintenance, UVV (accident prevention) inspections, and a pick-up and delivery service within a 30 km radius of Lüneburg.
