Drilling machine SBSH-250D

Drill cone drilling machine SBSH-250D is designed for drilling explosive boreholes with diameter 171-270mm in strong highly abrasive rocks. Diesel drive provides autonomy, which significantly reduces the time for moving the machine, independence from rewiring of quarry electrical networks. The 650hp Cummins QSK19 diesel engine installed on the machine is characterised by low fuel consumption and reliability.

Sequential arrangement of compressor, engine and pump unit facilitates their maintenance. A 2.5m3 fuel tank ensures daily operation of the machine. All machine operations: travelling, horizontising, lifting and lifting.

All operations of the machine: moving, horizon setting, raising and lowering the mast, feeding and rotation of the drilling tools, building up the drill string are provided by the hydraulic drive. The hydraulic drive made on the basis of mobile hydraulics by Bosch Rexroth ensures high reliability of the machine, smooth operation, absence of hydraulic shocks, significant reduction of noise and vibration, precision...
