Rotary Drill Rig SR250
Sany America offers seven different drill rig models in the US market. These machines range from 110,633 ft-lbs (150 kN.m) max output of torque with the SR130 to 265,519 ft-lbs (360 kN.m) max output of torque with the SR360 drill rig. Sany America offers customers a choice of excavator base units manufactured by either Caterpillar® or Sany. The undercarriage is driven directly by a planetary gear system and two hydraulic motors. The power module consists of a Cummins/Cat/Isuzu turbocharged diesel engine directly coupled on one end and a hydraulic pump drive on the other end. This complete power module assembly is mounted on its own sub base, which in turn, is mounted to the rig frame. The engine drive train configuration maximizes mechanical efficiency. A heavy duty engine silencer/muffler is provided to reduce engine noise emission. Engine air cleaners have quick release dust drop covers, as standard, for easy maintenance. All drilling and propel functions are hydraulically powered. The hydraulic system consists of Rexroth, Kawasaki, Cat or Brevini components, depending on the model of machine. A hydraulic oil cooler assures cool oil temperatures to maximize system efficiency and component life.
