Positionsanker

Positionsanker is a term used in German engineering and related fields to denote a device or method that fixes or references a specific position of an object within a larger system. The core purpose is to resist disturbances and to enable precise, repeatable placement or maintenance of a location.

Positionsanker are used across several domains. In maritime and offshore contexts, anchors and mooring systems keep vessels or equipment at a defined location relative to the seabed, including fixed and dynamic positioning setups. In civil and structural engineering, anchor bolts, anchor plates, and other fixtures secure components to concrete or rock, providing a defined reference point and resisting tension, shear, and overturning moments. In surveying and geodesy, reference markers or benchmarks define precise geographic positions used to orient measurements and map data. In manufacturing and assembly, locating fixtures and pins position workpieces during machining, welding, or assembly, enabling repeatable accuracy.

Design and installation of a positionsanker involve selecting elements capable of carrying expected loads, often made of steel or stainless steel with corrosion protection. Installations require correct placement, proper torque or tensioning, and verification of the reference position. In critical applications, redundancy and monitoring may be implemented to maintain performance over time.

Maintenance and standards typically include periodic inspections for corrosion, wear, and looseness, with replacement or re-tightening as needed. Design and installation follow relevant national or international standards and project specifications to ensure safety and reliability.
