Rotary Blasthole Drilling Rig (YTR300D)

YTR300D rotary blasthole drilling rig adopts parallelogram structure of dual boom, which is featured with good flexibility and high construction efficiency. At the same time, torsional capacity of luffing mechanism is enhanced to make it more suitable for hard rock construction in the southwest region.

Performance characteristics of rotary drilling rig

1. Parallelogram structure of dual boom is used to realize flexible movement and high construction efficiency, while enhancing torsional capacity of luffing mechanism, so that the drilling rig can become more suitable for hard rock construction in the southwest region.

2. Impact winch is fitted with freefall releasing reducer. When confronting with hard rock drilled difficultly, the impact winch can lift up the percussion hammer to break rock and then collect broken bits with the drilling bucket, increasing rock breaking efficiency; in case of construction involved with pebble bed, the impact winch can be used for percussion and squeezing to form protection wall; in case of construction involved with backfill soil, the impact winch can be used for percussion and compaction to form solid protection wall and avoid landslides;

3. Telescopic chassis is used to meet various transportation conditions and widen the whole machine at work to 4.3m and enhance machine stability and construction safety;

4.  

   Casing tube is optional, which may help to carry out the full casing tube construction method;

5.  

   Forehead oil cylinder is added to realize automatic folding mast of the pulley yoke, reduce labor intensity and increase work efficiency.
