MNB-50 / Directional rod pusher
This is a small-sized unit, with the pulling capacity of 50 tons, for construction of average-diameter pipelines in urban environment.
Simple, versatile and reliable ground-piercing tool with the pulling power of 50 tons. Modular mounting system enables operation in standard rectangular trench box or a special OR-1.5 shoring system for depths up to 5.5 meters, as well as directly in a 1500 mm well.
MNB-50 equipment set is provided with hydraulic power
pack with connections for the machine’s hydraulic power cylinder, as well as
various hydraulic instruments (such as jackhammer, pump, circular saw, chain
saw, jig saw, drill, nut runner or valve rotation device).
- Installation of new pipes up to 315 mm in diameter at the distance of up to
- Trenchless replacement of old pipelines up to 315 mm in diameter by means
of static pipe bursting
The MNB-50 unit’s principal competitive advantage is its wide range of functions. Minimal excavations for pits, with the minimal disruption of surrounding areas, make the MNB-50 unit particularly useful in 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 its class due to its good combination of price, versatility, scope of applications and small size.
Options for the MNB-50 unit installation and operation:
- from the pit (3 m long, 1 m wide);
- from OR-1,5, the formwork manufactured by MEMPEX JSC (2,5 m long, 2 m wide);
- from the existing well (Ø 1500 mm).
No bentonite mixtures required.
Soil types: up to and including the 3rd category.
Worn pipeline replacement parameters:
- 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.
