The propeller installation platform in marine engineering is a precision tooling system designed specifically for the integrated assembly of large-scale ship propulsion systems. Its core function is to achieve high-precision positioning and reliable fixturing of multi-ton propeller assemblies. Combining a modular steel structure base with a three-dimensional adjustment mechanism, the platform creates a workspace that meets the requirements for key processes such as propeller installation, centering adjustment, and bolt pre-tightening, ensuring accurate docking of the propulsion system with the stern of the ship.
