Characteristics of the vehicle:
- the nominal drilling depth shall be used by drilling tube 127mm: 2000-3200m and drilling tube 114m: 2500-7000m.
- ac – scr-dc drive energy system (ac – dc – ac for single-axle winch). Winches, rotor and drilling pump of the drilling rig perform all mode, and has a remarkable drilling capability.
- the winch switches gear through the couplings pneumatic.
- main brake – hydraulic disc brake, auxiliary brake – brake with electromagnetic vortex current or Eaton brake.
- rotor drive form – a separate drive or recombination drive.
- the two-lift base allows the platform towers and tools to mount in the lower position, then with the power of the winch or the device of a separate winch performs the whole lift.
- the main units of the drilling rig comply with the API standard and are allowed to use the API logo.
