Why Hydraulic Dish Control?
I was asked many times, what inspired me to move the dish by hydraulic engines in azimuth and elevation.


The Pro's for hydraulics:

  • Lots of power: no matter how heavy your system is, you can move any weight.
  • No counterweight needed. You better use the concrete blocks for appropriate basement of your tower!
  • Ideal for outdoor use! No matter how wet, cold, hot or icy everything is, it works. Electric motors don't like water and snow!
  • Precise control. Slow movement with hydraulics is easy.
  • No mechanical shift. Hydraulics are not impressed by winds. No mechanical gear.
  • minimal maintenance requirement


The Con's against hydraulics:
  • heavy structures. Indeed, hydraulic engines are heavy. Your tower has to cope with this.
  • You might not be familiar with hydraulics. Once you recognize it's value, you'll be an expert soon!
Hydraulics Tutorial
