Lifting of DHT reactor along with 8 other smaller units
To erect a DHT reactor. Our challenge was to place our 1000T crawler crane with self weight 800T along with 500T mobile crane used as tailing crane. The most difficult challenge was to position the 2 cranes near an excavated area.
Ground pressure calculation was done to know the load released. We used steel plates to reduce the ground pressure. Calculation was also done for top and tail operation to choose the crane best suited for the operation. After the top and tail operation the crawler moved with a 204T load to reach the foundation at 36m.
