SEBA cable way installation type SKA

The SEBA cable way installation SKA is deployed to measure discharge in rivers and channels. Depending on the kind of waters and the maximum possible current velocity, a suspended current meter equipment, with sinker weights of 25,50 and 100 kg can be used.
For the different fields of application and the different local conditions, several types of cable way installations are available:
Type SKA-T:completely portable cable way installation for quick mounting at site (pic. 1)
Type SKA-S-T: stationary cable way installation with portable double drum winch and crane trolley. (pic. 2)
Type SKA-S: stationary cable way installation with tension of track- and tow-cable by turn-buckles (pic. 3)
Type SKA-G: stationary cable way installation with tension of track- and tow-cable by weights(pic. 4)
Type SKA-H: stationary cable way installation with hydraulic tension of track-cable and tension of towcable by turn-buckles.(pic. 5)
By means of the double drum winch, the meterbody can be moved horizontally and vertically. The corresponding position of the meterbody can be determined by means of the two counters. So a determination of current velocities from river banks is possible.
Due to the solid construction of the stationary cable way installation, a safe operation is possible even under extreme environmental conditions. (flood, extensive span etc).
