DL-TS3600 jacking tower system for the erection of petrochemical vessels

The DL-TS3600 is a new jacking tower system designed and supplied by Dorman Long Technology to Sinopec Tenth Construction Company in China. The tower system has a gross lifting capacity of 3600 tonnes in two tower configuration and 7200 tonnes in four tower configuration. The main features of this tower system are as follows :
  • 7200 metric tonnes gross lifting capacity on four towers
  • 2-tower and 4-tower, guyed and free standing configuration options
  • DL-CP600 pinned climbing jacks used for lifting. 600 tonnes lifting capacity per jack. Each tower can be fitted with two or three of these jacks.
  • All components designed for transport in standard shipping containers
  • 3600 tonne capacity lifting beam spans between a pair of towers and is lifted with the load, removing the need to erect and dismantle this beam at height and avoiding a large wind sail at the top of the tower in the out-of-service storm wind condition.
  • Self-erect and dismantle option, with the 11.85m long fully assembled tower sections being inserted and removed at the bottom of the towers
  • DL-P40 central computer control of all jacking systems for accurate monitoring and synchronisation. This control system has many automatic functions included, including overload protection and full data logging.
  • Vessel can be moved longitudinally and transversely after lifting
  • Vessel can be rotated after lifting using an optional 360 degree swivel.
Erection of first vessel in February 2016 using a U-frame lifting beam. Tower height = 90m. vessel height = 120 m. vessel weight = 2520 tonnes.....
