SiamMaster - GDIS 2-6 URAL/KAMAZ


  • electric-driven pulling-and-running and electronic control mechanism «SIAM-LESP-6». Power supply is from three-phase industrial network 380 V, 50 hz;
  • self-contained power supply of the pulling-and-running mechanism is a synchronous generator driven by additional engine pto providing complete independence of operation;
  • AC frequency changer provides infinitely variable speed control of lowering slickline from 7% to nominal;
  • change in direction of slickline movements is made by changing rotating direction of a motor shaft - electronic reverse;
  • running depth gauge MI-1 doesn’t have a measuring wheel (excluding redundant slickline strain);
  • free fall is provided by a belt brake of a drum;
  • 2 speed rates (differ in speed by three times) : power or fast. Gears are changed in complete stop and full braking;
  • speed, running depth and pulling force is controlled by an electronic meter. The running depth control is duplicated by a mechanical meter;
  • there are 2 working areas cabined off with a watch window in the vehicle: an engineering compartment and operator control room. There is a small size door between these rooms. Slickline is run through rear locker doors;
  • to light the wellhead and slickline winch, 220 V line-operated spotlamps are installed;
  • there is an amplified telephone;
  • to improve working conditions, the following equipment is installed: a washstand with a water heater, a wardrobe, sleeping berths, a chest, an operator seat and so on (optional);
  • it is equipped with a hoisting device to change a drum (optional);
