Markets & Applications Civil Engineering Hydraulic Technologies in Civil Engineering To protect man from the elemental force of water and, at the same time, make the most use of water power - hydraulic technologies with hydraulic steelwork are able to accomplish both. Opening flood and lock barriers, produce energy in weirs and dams, lift and lower ships, move bridges - Bosch Rexroth proves its competence in all fields - worldwide. In close cooperation with planning and operating companies of such plants, Bosch Rexroth has developed hydraulic drive systems for hydraulic steelwork. Like no other drive technology, hydraulic systems offer high operational reliability, high power desity, compact design, permanent solidity, minimum required maintenance and excellent regulating capacity combined with control electronics - which are the best conditions for hydraulic steelwork. Innovative technologies, such as the development of Ceramax piston rod coating or of the position sensor system CIMS, contribute to the increase in solidity, corrosion resistance and thus service life of hydraulic drives. The use of servo or proportionally controlled pumps enables infinitely variable adjustment of travel speeds and deceleration times, accurate sychronous control and energy saving as well.
