MODULAR DESIGN
The modular layout of components on the drill makes it easy to replace worn components in the field, minimizing downtime, and enabling more flexible usage.
SAFE
Advanced safety features such as a rotation barrier, mainline winch tensioner, and an optional wireline spooler ensure safety in tough drilling conditions.
RELIABLE
A simple hydraulic and structural design makes this drill easy to operate and maintain.
MOUNTING OPTIONS
The LF90D surface diamond coring drill features a telescopic dump mast making it ideal for truck or crawler mounting to suit site conditions.
VERSATILITY
The LF90D is ideal for both wireline coring and rotary drilling with tri-cone bits.
Features
1. SELF-CONTAINED OPERATOR
The simple hydraulic system is easy to operate and maintain and lift-to-shift levers provide additional operator safety.
2. SIMPLE HYDRAULIC DESIGN
Direct-coupled hydraulic pumps with a PTO driven auxiliary pump allow for easy maintenance.
3. NITRO-CHUCK™
Patented nitrogen gas spring jaws with hydraulic open/spring close function ensuring fail safe operation.
4. ROTATION BARRIER
Interlocked rotation barrier slows rotation when the barrier is open, providing additional operator safety. Mainline winch limiter and tensioner prevent over-winding and bird-nesting of the cable.
5. HYDRAULIC SLIDE-SHIFTING HEAD
Lowers working height when handling inner tube.
6. DUMP MAST
Lowers working height when handling inner tube.
