LF™230

MARKETS: Mineral Exploration

The largest of the LF™ series, the LF™230 not only provides more power to drill deeper, but also has 9 m rod pull capability for increased productivity.

  • 18 ton capacity mainline hoist
  • Ergonomic operator panel with electric over hydraulic controls
  • 22.7 ton pullback, 3.35 m stroke direct-coupled feed cylinder
  • 9 m rod pull capacity
  • PQ™ Hollow spindle rotation unit with 4-speed transmission 45 degree to 90 degree angle capability
  • Nitro-Chuck™ with 222 kN holding capacity
  • Hydraulic powered rod clamp with BQ™ rod to HWT casing jaw sizes
  • Hydraulically driven wireline winch with integrated spooling device

LF™230 Features1. Dump Mast

Lowers working height and relieves load on the mast, making for more efficient design.

2. Ergonomic Operator Panel

The electric over hydraulic system reduces operator fatigue, and lift-to-shift levers provide additional operator safety.

3. Simple Hydraulic Design

Direct-coupled hydraulic pumps with a PTO-driven auxiliary pump allow for easy maintenance.

4. Rotation Barrier

Interlocked rotation barrier slows rotation when barrier is open, providing additional operator safety. Mainline winch limiter and tensioner prevent over-winding and bird-nesting of the cable.

5. Hydraulic Swing-Out Head

Lowers working height when handling inner tube.

6. Nitro-Chuck™

Patented nitrogen gas spring jaws with hydraulic open/spring close function ensuring fail safe operation.

7. 9 M Rod-Pull

Increases productivity.

Small Footprint

The compact design, as compared to other machines in this class, allows for easy transportation and a smaller site footprint.

The figures in these tables have been calculated, based on field experiences, and may be reasonably expected. Ratings are based on a vertical, straight, clean down hole using a 18 258 kg (40,000 lb) hoist (single line pull). Actual drilling capacity will depend on in-hole tools, conditions, drilling techniques and equipment used.
* BQ capacity shown for comparison purposes only. It is not recommended drilling practice to drill over 2 000 m BQ depth. Always verify manufacturers rod depth ratings prior to use.

components during operation or for service and manintainance.

Fluid Circulation Pumps

This triplex mud pump is the pump of choice for diamond drilling.


Output: 132L/m @ 55 Bar (35GPM @ 900PSI


Direct coupled hydraulic motor for long life and serviceability


Each pump module is equipped with a relief valve, pressure gauge, suction and discharge assemblies, lifting bar and skid base


Infinitely variable water pump speeds controlled from the operators console for optimum control

Mast Rest (Truck and Mount Version)

Provides support to rest the mast during transportation of the drill rig.

Mud Mixer

Having a reliable mud mixer in the field is an integral part of the drilling process, because drilling additives require a homogenous slurry mix to make the most of their lubricating and/or stabilizing properties
The robust, reliable and durable slurry/mud mixer has a max speed of 2300rpm at full flow
Powered directly from the drill rig’s hydraulic system, it is tough enough to operate in any drilling environment
Optional 150 gallons or 250 gallons mud tank

Mud Tank

This Mud Tank holds 250 gallons of drilling fluid and has 4 outriggers for support.
