XR460E

Rotary Drilling Rig
XR460E
Max. drilling diameter (mm): Ф3000(Remove mast I) Max. drilling depth (m): 72/110 Engine Brand: Cummins
XR460E

The telescopic crawler chassis with  swing legs is adopted to meet the  stability of large tonnage drilling rig and the convenience of disassembly and transportation,itis equipped with large  diameter  slewing  bearing  with  stronger  anti overturning ability;
The power head adopts vertical pin  shaft connection type power box and bracket, which has  high  reliability  and  is  convenient  to  disassemble;the  power  head has ommon mode,rock entry mode,medium speed rock entry mode and energy-saving mode,and  users  can  select  corresponding  modes  according  to  different geological conditions,which improves construction efficiency and reduces fuel consumption; The main winch  adopts  single row rope,the  service  life  of steel wire rope  is  2~4 times longer than that of multi-layer rope,and the use cost is lower;
The main and auxiliary hydraulic systems adopt load sensitive control technology, with  fast  response  and  good  control  performance,the  double  overhead  cooling system  is  adopted,which  can  intelligently  adjust the  cooling  capacity  according to the temperature,with strong cooling capacity,energy saving and noise reduction; Equipped with  Cummins  15L  electronic  control  turbocharged  engine,it has  strong power,low  fuel  consumption,convenient  and  fast  service,and  adopts  decentralized ndependent cooling system,with strong cooling capacity and low noise;
The  intelligent  control  system  realizes  the  functions  of automatic  adjustment  and display  ofdrilling  mast  verticality,automatic   spin-off(adjustable frequency),cruise control,stepless   pressure   adjustment,bottom   touch   protection,etc,it   adopts   bus panel  design  to  prevent  misoperation,it  is  equipped  with  12  inch  touch  screen display and electric control handle to achieve better control performance.
