Turbine Casing Adapter for Mobile Crane Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual mounting and removal of turbine components, particularly heavy blades, is challenging due to their weight and the disadvantageous working position, leading to unsafe and labor-intensive operations.
Innovation Solution
A method involving the fastening of a crane directly or indirectly to the turbine casing, using an adapter, allows for the safe and efficient transportation and installation/removal of components by leveraging the crane's proximity and the turbine's counterweight, eliminating the need for heavy counterweights and enabling flexible positioning with a mobile crane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual mounting and removal of turbine components is performed, then no additional equipment is needed, but the operation becomes labor-intensive and unsafe due to heavy component weight and disadvantageous working position
Solution Approach 1:
A mobile crane serves as an intermediary device between the turbine components and the operators. The crane is fastened to the turbine casing via an adapter, allowing it to lift and position heavy turbine blades without requiring operators to manually handle these heavy components, thereby improving safety while maintaining operational ease
Solution Approach 2:
The turbine casing itself serves as the counterweight for the mobile crane, eliminating the need for separate counterweight equipment. The adapter utilizes the existing structure and weight of the turbine casing to provide stable support for the crane during component mounting and removal operations
2Adaptability or versatility
If a crane is fastened directly to the turbine casing, then heavy counterweights are eliminated and flexibility is improved, but the turbine casing must be adapted with additional fastening structures
Solution Approach 1:
The adapter serves multiple functions: it provides fastening points for the mobile crane, utilizes the turbine casing structure as counterweight, and enables flexible positioning of the crane. By creating this multi-functional adapter, the system achieves versatility without requiring extensive modifications to the turbine casing design
Solution Approach 2:
The adapter acts as an intermediary component that connects the mobile crane to the turbine casing. It includes a base plate with fastening elements that attach to the casing, and an upper structure that provides attachment points for the crane, thereby enabling crane mounting without direct modification of the casing structure
3Stability of the object's composition
If heavy counterweights are used with the crane, then stability is improved, but the overall weight and complexity of the equipment increases
Solution Approach 1:
The turbine casing serves as the counterweight for the mobile crane, utilizing the existing heavy structure of the turbine itself. This self-service approach provides the necessary stability for crane operations without requiring separate counterweight equipment, thereby maintaining stability while avoiding additional weight
Solution Approach 2:
The adapter is designed to utilize the turbine casing as a counterweight, positioning the crane such that the heavy casing provides the necessary balancing force. This eliminates the need for separate counterweights while maintaining crane stability during component lifting operations

AI summary
A method for mounting and/or dismantling turbine components is provided. According to this method, a crane is fastened to a turbine casing half in the area of the joint, and at least one component such as for example a turbine blade is brought into its mounted position and/or is removed from its mounted position by means of the crane. For this purpose, the crane has a tower with a multiple section jib having a plurality of segments, thereby allowing the components to be positioned accurately for mounting/dismantling. The mobile crane is connected to the turbine casing half by means of an adapter. The adapter has a fastening pin which is held in place by means of an existing through-bore in the turbine casing half. For the purpose of mounting the mobile crane, the adapter has a baseplate. For rotational locking of the crane, a securing element is provided.
