Model DH
- FS |
|
|
|
|
|
The unique
feature of the DH-FS type is that it can be jacked from a small starting
pit. It's
structure can be divided into 4 smaller portions meaning that it can be
collected from an existing manhole. A
hydraulic drive system is employed, realizing powerful excavation
performance as well as being a space saver. |
