MNB-50 Directional Drilling Machine
Small-sized unit, with the pulling capacity of 50 tons, for construction of average-diameter pipelines in urban environment
- Directional boring with dry method at the distance of up to 120 meters
- Replacement of old pipelines up to 200 meters long
Installation and operation options for the MNB-50 unit:
- from the pit (3 m long, 1 m wide)
- from OR-1,5 formwork manufactured by MEMPEX (2,5 m long, 2 m wide)
- from the existing manhole (Ø 1500 mm)
No bentonite mixtures required.
Soil types: all types except rocky soils.
Worn pipeline replacement parameters (pipe bursting):
- easy operation;
- small overall sizes;
- low cost.
The MNB-50 unit’s principal competitive advantage is its wide range of functions.
Minimal excavations for pits, with the surrounding areas remaining maximally untouched, make the MNB-50 unit especially appropriate for confined urban conditions.
MNB-50 works reliably under severe winter conditions in Russia, Belarus, Ukraine and Kazakhstan.
MNB-50 is the most popular unit in the relevant class, due to its good combination of price, versatility, scope of application and small sizes.
MEMPEX JSC offers new applications for MNB-50:
Since November 2009, the MNB-50 equipment kit is provided with the new hydraulic unit; not only the machine’s hydraulic power cylinder can be connected to it, but also various hydraulic equipment (such as a jackhammer, a pump, a circular saw, a chain saw, a jig saw, a drill and even a nut runner or a valve rotation device).
