LOCK DRIVES - HIGH STABILITY

Constructing a lock places high demands on the components and materials used. Locks must be stable enough to hold back up to 600,000 m³ of water. This also opens the door for interference in the output of the motors that open and close the locks. A mechanical overload function in the drive is indispensable for preventing the lock gates and their drives from being damaged due to incorrect positioning of a watercraft as the gates close.


A solution for this application was found with R+W as a development partner. A ST series heavy-duty safety coupling was used, which satisfies corrosion resistance requirements. The coupling also includes a special seal which protects the device from any water ingress. Another advantage for the lock operator is in the fact that these rugged safety couplings are maintenance free and therefore do not generate any additional follow-up costs.
