A 650t crane was rigged up and lifted the ring beam assembly above the silo. Stay cables were used to secure the ring beam at 44m. Two 250t cranes are used to connect the rafter assembly (25t each). Once the rafters have been assembled, the silo’s load is gradually released.
The entire penthouse set (150t) of dimensions (15m x 15m x 22m) is lifted and placed on top of the ring beam with a rafter.
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.
