The СБШ 250-40 ДГ “Universal” (hereinafter referred to as the machine) of rotary drilling with a hydraulic drive based on Bosch Rexroth components and a Cummins QSK19 diesel engine is specially designed for drilling blast holes in rocks of various strength categories and drillability classes in open pit mining way.

Drilling depth of 40 m with a rod of 8.5 m. The feed pressure creates a force on the bit of 270 kN. Due to the diesel drive, the autonomy of the machine is ensured and the time for its movement is reduced, which does not depend on the rewiring of quarry electrical networks.

All technological processes – drilling, changing bits, assembly and disassembly of the drilling string – are mechanized and automated as much as possible.
