The Lower Drill Method will realize any kind of pile work in any kind of ground.

• Execution at steep slope
• Execution of scaffold board
• Execution of retaining pile and soldier beam as the countermeasure for ground falling
• Execution at narrow site or railway neighbourhood site
  

Execution at steep slope

Because of its compact size and light weight,the value of Lower Drill will be exerted in such steep site as substructure of highway or side road for dam. Even at severe slope, safe and short term execution is possible within the radius of crane action. 

Execution of scaffold board

With temporary scaffold or bridge which stretches along mountain or river, only one crane can cover the whole work from excavation to execution. Smooth and efficient execution will be realized by stretching-arm-in-the-air method. 

Execution of retaining pile and soldier beam as the countermeasure for ground falling

Because it is possible to adopt the most suitable excavation method depending on each subgrade condition, screw, trowel or down-the-hole hammer, it can cope with changes of digging subgrade flexibly, thus assuring speedy execution possible.

Execution at narrow site or railway neighbourhood site

In such sites as under wiring or crossbeam, in the neighborhood of railway or in a plant where a big size machine can't be carried in because of safety and installing space limitation, Lower Drill with light weight, compact size and low gravity will exert it versatile ability.
