About the EK250 Bottom Drive CFA
The EK250 Bottom Drive CFA is configured using The revolutionary patented system Bottom Drive CFA that has the following advantages:
- The new Cat® 340 Next Gen powered by a fuel efficient Tier 4 Final C9.1 ACERT engine.
- Significant improvement of stability, providing greater security in the operation of CFA
- Optimal ratio of drilling depth x equipment weight due to lower center of gravity, enabling lower transport weight and lower transportation costs.
- Hydraulic pull-down on the rotary, centered to the drilling auger, improving the penetration in hard soils.
- Highly effective drilling torques due to the robust drilling head.
- Better efficiency of power due to the short length of hydraulic hoses that feed the drilling head, resulting in lower pressure loss.
- Lighter drilling masts as a result of there being no need to resist high drilling torque at the top.
- Higher Extraction force, resulting from the addition of push-up of the cylinder to the winch extraction force.
Base:
- The new Cat® 340 Next Gen powered by a fuel efficient Tier 4 Final C9.1 ACERT engine.
- Equipped with Cat® Vision Link that allows management to monitor machine operations and maintenance data online.
Undercarriage:
- Caterpillar® variable undercarriage VH5000/4300/800. Reinforced frame H style variable undercarriage.
Mast:
- Reinforced mast, with high resistance steel Weldox 700.
Main Winch:
- Special groove for better cable winding and longer cable life.
- Press-roller included.
