LF™160 Drill Rig & Freedom™ Loader

MARKETS: Mineral Exploration

Boart Longyear has combined proven technology from its most popular surface coring drill rigs to create the powerful LF™160. When paired with the FL262 FREEDOM™ Loader, the LF160 combination is ideal for contractors who want to target sophisticated surface drilling exploration contracts that stipulate some of the highest safety standards, without compromising on productivity.

  • Totally hands free rod handling
  • Optimal safety without compromising on productivity
  • Designed to today's rigorous CE standards
  • Up to 1,800 meters of NQ™ depth capacity

1. Tilting Top Drive Head

The forward tilting head design simplifies the rod handling process and reduces the need for operation intervention and maintenance.

2. Clamping and Breaking Device

A hydraulic breaking device means No Wrench Under Power. Rod Alignment Device and Centralizer included.

3. CE Certified

The LF™160 is CE certified according to the latest safety standards.

4. Visual Wireline

The wireline winch and sheaves are located in the front of the mast, inside the rotation barrier, for improved visibility.

5. Depth Capacity

With up to 1,800 meters of NQ™ capability, the LF160 can cover the majority of diamond coring needs.

6. Environmentally Conscious Tier 3 or 4 Engine

Offered with either a Tier 3 or 4 final engine to comply with emissions requirements in every country.

7. Versatility of Carriers

The LF160 can be ordered in either a crawler or truck mount configuration. The truck mounting is compatible with international 6x4 and Mercedes 8x8 or 6x6 trucks.
