Krapphofschleuse, Ship lock in Hamburg-Allermöhe

Krapphofschleuse is a lock in Hamburg-Allermöhe that links the closed-off Dove Elbe with the Bille. It sits at the southern end of the Schleusengraben, one of Germany's oldest artificial waterways, which provides access to Bergedorf harbour. The lock was built in 1929 and equipped with a self-service system for recreational craft in 2006.

The lock was built in 1929 and stands at the southern end of the Schleusengraben, one of Germany's oldest artificial waterways. A self-service system was added in 2006, allowing recreational boaters to operate the lock without staff assistance.

The lock sits at the south end of the Schleusengraben, the artificial channel that gives Bergedorf harbour its access to the water. Since 2006 boaters have operated the lock themselves, so passing through is part of the trip rather than a service performed for them. Paddlers use a separate boat slip in the weir arm east of the lock, under a road bridge.

The lock sits at the southern end of the Schleusengraben, the artificial channel leading to Bergedorfer Hafen. Since 2006 boaters have operated it themselves, so a crew can be seen working the gates. Paddlers bypass the chamber by carrying canoes over the boat slip in the weir arm east of the lock, under the road bridge.

Canoes can bypass the lock via a boat slipway in the weir arm of the Schleusengraben, east of the lock and beneath a road bridge. It lets paddlers portage around the chamber instead of waiting for it to cycle.
