Features:
1.Two main optional type: CG series for Rotary drilling rig, Hammer Grab series for crawler crane.
2.PLC function: automatic oscillating and automatic change the direction, fast oscillating, remote control operation
3.With separate controlling system, to realize the biggest capacity (lifting force, oscillating force to the maximum.
4.Safty production: it has warning system when it reach the low hydraulic oil level or if the filter was blocked.
5.Energy saving: with cooling system, can save the energy.It will circle when it works, if no works, it will remain the standby state.
Advantages:
1.Environmental sound and safety foundation drilling method (drilling and grout with casing, no mud).
2.Widely used in difficult formations where there is a risk of collapse or broken formation, such as quicksand, flowing and plastic soils, high pressure groundwater formations, gravel and detritus-type soils etc.
3.High quality for cast in-situ pile and secant pile wall.

The Features of Full Casing Rotary Drilling Method:
1-High efficiency construction: Oscillator drive the casing(Protect wall during drilling and cast in place ). Rotary rig take out soil from casing (High efficiency drilling)
2-Safty construction: Double isolated by casing during drilling and cast-in-place, no disturbance to surrounding building foundation (near subway and high-rise building construction)
3-Environmentally friendly construction: No mud discharge, dry drilling, and the drilled rock and soil can be recycled.
4-Broad-spectrum construction: suitable for all kinds of complicated formations, gravel layers, strong weathered rock formations; casing drilling ahead in soft layer , drilling tools ahead in hard layer.
5-Casing verticality: Rotary rig controls verticality in shallow layer, and oscillator controls verticality in deep layer.
6-Power pack of oscillator: Independent power pack(Oscillator and Rotary rig operate independently, do not interfere with each other), or use the power from the rotary rig.)
