Hydraulic MGY-135L crawler mounted drilling rig for anchoring ,grouting, dams

MGY-135L crawler mounted hydraulic anchor drilling rig is a full hydraulic anchor drilling rig, it is suitable for deep foundation pit support of urban building and control the displacement of the building.The rig is unitary style, and with a crawler chassis and gripping and screw-off device which can remove the drill pipe and casing automatically.The crawler chassis moves  quickly, and locates the hole position conveniently to reduce the labor intensity and improve removal efficiency. 

Features:

1. hydraulic control , instrument display , easy and flexible , easy to move , good mobility . Critical hydraulic components are imported and domestic famous brands.

2. rotary drilling rig adopts double hydraulic motor output torque, lower center of rotation than similar products , greatly improving the smoothness of drilling rigs .
3. the new variable angle mechanism to make it easier for holes , larger adjustment range can reduce the requirement for working face .
4. customer specific local conditions, cooling system is optimized to ensure that the hydraulic system work normally when the outdoor temperature is 45 º , the maximum temperature doesn't exceed 70 º.
5. with a dedicated drilling with drill ( drill pipe , casing , eccentric drilling tools , etc. ) , in an unstable earth formation, make open hole with casing hole-boring method , conventional button bit to finalize hole. High drilling efficiency , good quality of the hole .
6. the rig is mainly for anchoring and deep foundation pit, but also for jet-grouting after the jet modular head replaced.
7. MGY-135L crawler chassis rig besides clip teeth shackle and the turntable , we also provide users with a jet modular option , the user can order rig’s options to make our rig more suitable for your project .
8. the main drilling methods : DTH conventional drilling, TC bit drilling , auger drilling.
