In the production of solid motors for rockets there are huge plants. At present one motor is prepared in five segments for ease of handling and operations. To increase the production of solid motors, it is proposed to adapt twin segment casting. A rocket segment each weights about 60tons, each segment will be with2.8m diameter. This segment will be provided with end ring on both sides which will be used for handling segment at various process work centres within the plant. This segment has to handle with overhead cranes [EOT cranes] using a proper grabbing type handling system this operation requires lot of time and effort. To reduce the time and effort and to increase the productivity it is proposed to design a grabbing type handling system which is operated remotely. This project deals with detailed design and analysis of grabbing system for handling twin segments capacity 120tons. This grabbing tackle system consists of top handling bracket, pin assembly, main beam, C-arm, pneumatic cylinder, manual drive, etc. All the above subsystems will be designed and analyzed with the help of SOLID WORKS and ANSYS workbench. Finally theoretical value and analytical values will be compared.

Keywords: Beam bracket, c-arm, pin, stress etc.
