COMPETITIVE ADVANTAGES:
A self-propelled drilling rig “MEDVED” (MBU-280) with a capacity of 1300 hf is manufactured with a view to a statistical load of 280 metric tons (no analogs in the Russian Federation).
The truck of own design consists of a frame, 7 axles (4 leading axles, capacity – 16 tons each, 3 movable axles capacity – 11 tons each), steering, ABS brake system.
Mast UM-280 is adapted for the installation of TDS.
The OB-MBU drilling platform is 5.4 meters high to the bottom of the rotary beam.
The drive of the main drives is carried out from the two paired CATERPILLAR C 18 diesel engines through a summing gearbox.
As the vehicle is self-propelled, the time it requires to move to the next well within the drilling site is significantly reduced.
Replacement of imported (Chinese) units with Russian ones at more affordable prices.
The assembly and disassembly of the MBU drilling platform takes no more than 15 hours.
