Screw jacks – special design

Screw jacks for all applications both on and offshore – customer-oriented
in size and design to provide the right solution in every instance




Our screw jacks are not only used successfully in the wind power industry, but
you will also find customised versions of the lifting systems used in the oil and
gas industry.
For example,screw jacks of the SHE200. 1Y-400 series are used for lowering gas
and oil pipelines from the installation vessel at a defined angle to the seabed.
This involves four screw jacks being mechanically synchronised, which move the
pipe guide belts on the installation vessel radially to allow the bearing pressure
and the belt distance to be adjusted to the pipe to be laid. The adjustment of the
tension force via the axial movement of the creeper bands also defines the pipe
installation angle.
