    Rudgormash received visitors from PJSC “Stoylenskiy GOK” on October 25, 2016 who had come for preliminary acceptance of the drilling rig SBSH-250 that had been manufactured by that time and was being prepared for the shipment. The drilling rig fundamentally differs from


 

The drilling equipment

Drilling rig SBSH-160/230

Drilling rig SBSH-160/230
 
Hydroficated rotary drilling rig with an electric drive serves to drill blast holes in rocks with hardness from 6 to 18 units according to prof. Protodyakonov scale at open mines as well as to drill deviated contour holes.

 

The components of the drill are situated on the platform which stands on the crawler mounting unit of excavator type.

All mechanisms of hydraulic system are fed by the major pump driven by an electric drive of 75kW powered by the voltage of 380 V.

The mast is a spacious welded construction with an open front side made of square pipes. Inside the mast there are a rotation and feeding mechanism, a separator for rods, a rest device and a screwing and unscrewing mechanism of the drill tool.


  • Load bearing constructions are made of alloy steel;

  • Hydraulic components are mobile and manufactured by Bosch Rexroth company;

  • The drives have load safety factor that greatly increases the life cycle of the major units;

  • the motors are cavitation protected even when the drilling rig travels downhill;

  • productivity regulation of the main pumps can be done upon customer’s request based on the operations it performs. The power of the actuating motor is diminished due to the optimal use of the regulated pump’s power specifications;

  • seamless connections of pipes and high-pressure hoses are applied in the hydraulic system that eliminates the problem of oil leaking;

  • modern measuring instruments are used to control the process of drilling;

  • all auxiliary operations are automated;

  • the track motors switch off during the drill towing;

  • optimal center adjustment of the machine with the mast up or down is provided on the drill.
