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.
