Shock absorbers for impact protection bars, shock absorbers for cable brake systems and guide rollers for lift gates
With our individual sluice buffers and guide rollers for lift gates, we support our customers in hydraulic engineering.
HYDROSTAT sluice buffers are used as a safety device on floodgates. In order to minimise the risk of damage to the floodgates, safety components such as impact protection bars or cable brake systems are installed. With a 1,000-tonne ship and a collision speed of two metres per second, the kinetic energy can reach 2,000 kilojoules. This energy is safely absorbed by the HYDROSTAT buffers during deceleration.
Thanks to the regenerative design of our buffers, the shock absorbers are ready for operation again following the impact. Replacement is not necessary.
