SR330 Rotary Drilling Rig
SR330 Rotary Drilling Rig
¡¤ With 80m Max. drilling depth and 2500mm Max. diameter, the machine has been widely used in deep pile foundation engineering construction of railway express, bridge, high building and etc. The machine is the ideal equipment of large size pile foundation engineering construction.
¡¤Innovative whole-processing pressurization device owns such advantages as simple assembled and easy to fit together modularly.
¡¤Engine with high power, low discharge, efficient, and environment protection.
¡¤Super output torque of 285kN·m ensures the implementation of the construction under different geological conditions.
¡¤FRYM mast controlling system realize the whole-processing control of the mast sidewards, operation efficiency has been increased.
¡¤Volumetric pump-motor speed-adjusting system increases the utilization rate of the energy, lower heat exhaustion has been realized.
¡¤ Imported key parts such as Hydraulic Pump, Hydraulic Motor, Hydraulic valve and Piping joints are introduced in well-known brand to assure high reliability of system.
¡¤Study on Modular Design realized new appearance.
¡¤Large crawler travel mechanism enhanced greatly the stability of the drilling rig.
