Advantages

1. High Productivity
   - Comparing with other methods, the productivity of Super Wedge is quit high level as much as 120 cubic meter per day with two crawler drill. Mainly the productivity is depends on the number of drilled holes by crawler drill. At the jobsite, the working speed is determined by drilling speed of crawler drill. The smaller hole is the key of speed and down the cost. Also, it is convenient to use Ø76mm bit which is international bit size and more cheaper than Ø89mm bit.
2. Safety
   - Super Wedge is mounted on excavator so, do not need personal power. It is possible to escape from injury or accident at the job site due to no man staying near the rock breaking area.
3. Noise Free, Vibration Free, Dust Free
   - It is not explosion method. It uses only hydraulic power of excavator. So, there is no Noise, Vibration and dust. It is very useful at the down town job site where we can not use explosion method.
4. Efficient operation
   - Just one Excavator can do Splitting, Digging and Cleaning. Installation of Super Wedge to excavator is so easy needs just 10 minutes. We use the same type of hydraulic pipe line as hydraulic breaker. Even man power, only one or two workers are enough to operate including operator of excavator.
