FRD Crawler drills – for the most demanding and varied tasks

Over recent years FRD has invested huge efforts in bringing superb crawler drill capabilities to the market, with the assurance of high cost-effectiveness, long life, low failure rate, low maintenance, and modest price. FRD crawler drills are the result of a lot of work by many experienced, committed and dedicated engineers who have done a lot of listening to clients.

Special benefits include:

  • On-screen information system means the operator has full view of machine status in real time.
  • The FRD dual damper system means maximum energy transfer by holding the bit against the rock at all times.
  • IDS automatic anti-jam and force control feature means optimum working time, and maximum efficiency.
  • In-Line-2 rod changer means fast rod change time.
  • Reverse percussion facility means easy freeing up of a blocked rod.
  • High output compressors mean high flush volume, fast drilling and low bit wear.
  • Low emission engines mean EU, US and Japanese regulations are satisfied.
  • Special rubber mountings and heater facilities mean comfortable operator working conditions.
  • Check crawler drill for specification details.

FRD Crawler drills for - highest drill performance at lowest operating costs.
