Lock damage (Besigheim, Neckar)

Besigheim lock is located on the river Neckar at the downstream of an approx. 0.6 km long lock canal and consists of a twin lock on the right-hand bank. The gates of the lock system are single-piece lifting gates on the lock head and two-piece lifting gates on the lock tail. The head gates on the lock head are also used as flood protection gates.

In September 2006, after the chamber water level in the right lock chamber had been set to downstream and the tail gate had almost reached the highest elevation, damage occurred on the drive system of the left winch. The intermediate transmission shaft upstream of the chain pinion shaft broke immediately at the hub of the large gear. This resulted in an interruption of the power train between the chain pinion shaft and the drive motor. As a consequence, the gate weight on the damaged side (left winch) activated the drive to "Lowering" in an uncontrolled manner and lowered the gate by about 2 m on the left side.

Subsequently, IRS was commissioned with the survey and the reconstruction of the damage event as well as with the development of a securing and repair conception for the gate.

Scope of planning:
- On-site inspection, damage survey and reconstruction of the damage event
- Development of a securing and repair concept for the gate
- Preparation of tender documentation for the required activities
