[Haichuan Engineering Updates] 2,000-ton crawler crane lifts 945-ton 96-meter 2# propylene distillation tower at Yulong Petrochemical
Thread Content
Recently, the No. 2 propylene distillation tower (945 tons, 96 meters) of Shandong Yulongdao Petrochemical’s 10-million-ton refining and chemical integration project was successfully lifted into place.
The structure being lifted this time is the No. 2 propylene distillation tower, which is 96 meters tall and weighs 945 tons (870 tons for the equipment itself, and 75 tons for the sling and lifting gear). It is characterized by its extremely high height and heavy weight. The construction company used a 2000-ton crawler crane to complete the lifting of this large and important item. It is reported that the total weight to be lifted this time is 945 tons, the rated lifting capacity of the equipment is 1120 tons, and the load factor is 84.4%.
To successfully carry out this major lifting operation, a custom solution was developed, featuring a specially designed split-load hook connection device that addresses the challenges associated with lifting gear connection and load redirection. A 1125t hook is used for this lifting operation; it is a variant of the 2000t main hook. By removing the two sets of pulley blocks and using the hook connection beam supplied with the equipment, the 2000t main hook can be quickly converted into an 1125t hook. The lowest part of this hook is not of the traditional double-anchor hook design, but rather a new type of special lifting device. The structural design can be carried out according to the requirements of the load to be lifted and the lifting plan, and it is put into use after rigorous theoretical analysis and experimental verification.
