YCJF-25 Full Hydraulic Percussion Reverse Circulation Drill
YCJF25 Hydraulic Percussion Reverse Circulation Drilling rig is designed and manufactured by our factory. The drilling rig is mainly used for deep foundation project of making bigbore and grouting pile construction. And apply to various stratums, especially in gravel formation and terrane, it is better in drilling efficiency and quality.
1, Patent products (patent number: ZL 03 2 17092.0), unique produce.
2, It is hydraulic transmission, impact way is hydraulic cylinder (Patent NO.: ZL 03 2 17089.0), impacting frequency and stroke controlled stepless regulation, automatic supply, high efficiency and low cost.
3, Monolithic construction of drill is reasonable, to realize all-in-one of machine, electricity, liquid. Auto impulse takes SCM control, function is advanced, working is reliable, and it reaches the first level in China.
4, Double drum synchronous hoist (Patent NO.: ZL 03 2 17091.2) can automatic leveling hammer, prevent sticking accident.
5, Drill matches hydraulic moving mechanism, it could move in job location, not heavy, small outside measurement, moving and transport easily.
