Drilling winch is designed for lowering and lifting the drilling tools, lowering casing pipes, driving drilling tools to bottomhole while drilling and its emergency lifting, rotation transmission to rotor, as well as for derrick lifting and lowering.
MAIN PARAMETERS
- Carrying capacity – from 250 to 500 tons
- Main electric drive – frequency-controlled
- Single-speed and two-speed
- Single-speed winches have a disk brake with the ability to slow down during operation
- Wide size range
Drawworks produced by USIC are our own patented development.
