Detailed Product Description

YG-80  construction  drilling  rig  is  a  full  hydraulic  operated  top  drive  power  head  drilling  machine.  It is  used  to  drill  heavy  duty  pretension  anchor  holes  at  side  slope  of  water  power  station,  railway  or highway  projects,  as  well  as  drainage  holes.  It  also  used  to  prevent  or  solve  geologic  calamity,  such as  landslide  and  rock  collapse  etc.  In  addition,  it  is  also  used  for  drilling  small  size  water  wells and  high-pressure  jet  grouting  holes.  It  has  been  already  widely  used  in  various  projects  such  as  water power  stations  in  Yunnan,  Guangxi,  Sichuan  and  Hubei  provinces.

It  has  also  become  the  first  priority  machine  for  medium-duty  anchoring-reinforcing  projects  in  China.

2.  Features

1)  It  has  great  drilling  capability,  wide  range  of  application  ,  rapid  drilling  speed  and  high  drilling efficiency,  as  well  as  powerful  ability  of  eliminating  accident.

2)  Extension  mechanism,  built-in  output  spindle  of  top  drive  head,  can  protect  drilling  tools effectively.  It  can  increase  the  hole  inclination  angle  range  and  drill  elevation  angle  hole,  while setting  the  top  drive  head  and  hole  top  plate  toward  the  opposite  direction.

3)  A  set  of  front-mounted  adjustable  columns  on  drill  frame  is  used  for  adjusting  height  of  mast  front- end,  which  makes  it  easy  to  align  with  hole  site.

4)  Rig  structure  is  separate  group  design,  it  assures  good  disassembility  ,  rapid  and  convenient  mount and  transport,  best  working  environment  and  lower  labor  strength  as  well  as  remote  control  and operation.

5)  Mast  can  be  fixed  on  staging  immediately  without  drill  frame  with  auxiliary  parts  (horizontal  axle and  buckles),  which  makes  it  possible  for  greatly  reduce  the  machine  weight  and  fastener  transport.

6)  The  imported  hydraulic  motor,  other  main  assembly  preferentially  selected  home  made  reputed  and  high quality  products  ensure  its  stable  running  performance,  reliable  product  quality  and  long  service  life.

It  has  good  interchangeability  due  to  the  high  grade  of  standardization  and  seriesization  of  wearing parts.

7)  Full  hydraulic  drive  and  operation,  stepless  shift,  simple  operation,  convenient  maintenance  and  few wearing  parts.

8)  It  can  be  used  with  various  drilling  methods  such  as  carbide  bit  drilling,  anger  drilling,  DTH hammer  drilling  and  follow-up  casing  drilling  etc.
