Hornet Sediment Sampler Model Hornet/SS
The Hornet SS has been developed to perform river and stream sediment sampling and discharge measurements from fixed cableways using suspended sediment samplers, conventional Columbus Type Gauging Weights (45 KGs Maximum) and Mechanical Type Current Meters or Acoustic Doppler Current Profiler (ADCP). The Hornet SS is an ideal solution for retro fitting to an existing manned cableway system, thus minimising the personal injury risk associated with this type of gauging.
The Hornet SS is operated from the bank of the stream. Using a wireless remote control (see Figure 1), which incorporates the latest state of art electronics and Radio Controlled Systems, the operator can manoeuvre the sediment sampler by the push of a switch to traverse across the span to be measured. Once into position, the meter is lowered to commence measurement.
The Control System operates an electric motor fitted with incremental encoder to drive the carriage and hoist from the operating side to the far side of the river and back to the start point (see Figure 2-3). A special Sediment Sampling function has been built into the Remote Control that allows the operator to dial in the depth where the sample is to be taken, and set the vertical speed of the sampler. The operator then simply holds the “Lower” button and the sampler lowers to the preset depth, stops, reverses direction, rises back up and stops at the starting.
