YF-HH-5A is produced with advanced technique & reliable quality, main components are world famous brands.
The drill rig has a reasonable design and superior performance.It is easy to operate and for maintenance.
YF-HH-5A adopts full hydraulic driving, travelling with crawlers itself. The drill head is driven by variable motor with function of two-speed mechanical gear shifts, stepless speed change with an advanced and simple structure. The rotator is fed and driven with a system connecting the spindle and oil cylinder with chain. If the piston rods of oil cylinder move one certain distance, the drill head will move double the distance. The mast could be adjusted within the range of angle 0 to 90 degree for its drilling hole with a low center of gravity and good stability of the overall unit. The rig provides operator with a nice field of vision and wide and comfortable working condition. The rig looks pretty in overall structure and embodies the design thought of people oriented.
Main components of this rig adopt world famous brands.
