we have worked out a multifunctional rotary drilling rig that can be attached to the excavator, with functions both as excavator and as rotary drilling rig.

we have built up our products from 7t to 30t which are mature both in technology and in production capacity. Now our products can drill max 50meters deep. And the max diameter 1.6 meters.

it is no longer difficult to fill the blank for 80% of mechanized and efficient construction machinery of middle-sized and small-sized pile foundations.
