Application
YGS-120 anchor drill rigs are equipped with two fully hydraulic operated top drive power head. They are widely used to drill large pretension anchor wire holes, large diameter anchor pipe holes, and grouting holes at the side slopes of impounding reservoir in water power stations, railways and highways, as well as small sized foundation pile hole, etc.

Features
1. With dual-top drive power head, the anchor drill rig can achieve various drilling methods, such as:
(1) While drilling a hole in 30-50m thick fractured zone and other troublesome zones, the drilling rig can achieve rotary percussion drilling by connecting the rear power head with the inner drilling tool and DTH hammer. Meanwhile, the front power head rotates the casing pipe for protecting the hole wall.
(2) While drilling a hole in ravelly ground, quicksand layer and silt layer, the anchor drill rig can achieve different types of drilling by using drilling tools like conventional rotary drill tool and long anger drill tool. Meanwhile, the front power head drives the casing pipe to rotate for hole wall protection.
(3) While drilling a hole in intact formation, the drilling equipment can use only one power head to achieve rotary drilling and rotary percussion drilling.
2. The anchor drill rig features high lift capacity and output torque, and has high drilling efficiency.
3. It is equipped with a clamping device and a breakdown device to achieve mechanical break-down of drill rod and casing pipe. This significantly reduces labor intensity and increases drilling efficiency.
4. Building-block style structure design and twin hydraulic pump system are distinct features of our anchor drill rigs. So, the equipment is convenient for mounting and dismounting, and is especially suitable for working in mountainous areas and other places with inconvenient traffic conditions.
