Key RME Upgrades & Benefits

  • Upgraded drill head — special seals prevent drilling fluid entering gearbox and oil contamination
  • Enhanced gearbox lubrication — higher-capacity pump and injectors maintain flow at low rpm / high torque (e.g. casing)
  • Protected relay box — relocated near engine, dry and easy to service (avoids flood risk under valve block)
  • Reinforced mast — improved structural strength for demanding programmes
  • Additional filtration — secondary, auxiliary and rotation-unit lube filters under control panel for easy service and longer component life
  • Extended steel frame (+20 cm) — better access for servicing hydraulics between tank and control panel

Field performance: OGK GROUP (Russia) set a record of 4,735 m HQ in one month with an RS-90 surface coring drill.
