Project execution: A crane has been rigged up and lifted the ring beam assembly above the silo. The ring beam was secured with stay cables at 44m. Then with the help of 2 x 250t cranes, the rafter assembly (25t each) is connected. The silo’s load is gradually released once the complete rafters have been assembled. After the ring beam is erected with a rafter, the entire penthouse set (150t) of dimensions (15m x 15m x 22m) is lifted and placed on top. As per the scope we initially lifted the 40m long conveyor in tandem with 450t and 250t cranes and erected it over the existing column and silo.
