Anchor Drill Rig

YTA series crawler anchor drill rig is suitable for the construction of rock bolt, anchor rope, geological drilling, grouting reinforcement and underground micro pile in different types of geological conditions such as soil, clay, gravel, rock-soil and water-bearing stratum.

   

Performance features

1. Multi-functional

YTA series crawler anchor drill rig is suitable for the construction of rock bolt, anchor rope, geological drilling, grouting reinforcement and underground micro pile in different types of geological conditions such as soil, clay, gravel, rock-soil and water-bearing stratum; it can realize double-deck rotary drilling or percussive-rotary drilling and auger drilling (through screw rod). By matching with air compressor and down-hole hammer, they can realize follow-up drilling of casing pipe. By matching with shotcrete equipment, they can realize the construction technology of churning and supporting.

2. Flexible movement, wide application

The cooperation of two groups of carriage and four-bar linkage mechanism can realize multi-directional rotation or tilt, so as to make the hydraulic crawler drilling rig realize the left, right, front, down and a variety of tilt movements, greatly enhancing the site adaptability and flexibility of the machine.

3. Good handling

The main control system of Series YTA crawler anchor drill rig adopts reliable proportional technology to provide simple, easy, and reliable operation, which is able to realize stepless speed adjustment and at the same time realize high and low speed switching quickly.

4. Energy saving

The flow distribution of hydraulic system is in accordance with the needs, avoiding overflow loss. Key hydraulic parts adopt more efficient plunger parts and imported parts, so as to realize the best utilization of the power of the crawler drilling rig.

5. Easy operation

YTA series crawler anchor drill rig is equipped with a mobile main control console. The operator can freely adjust the operating position according to the actual construction site condition, so as to achieve the optimum operating angle.

6. Adjustable upper-vehicle

Through the movement of a group of cylinders which are mounted on the chassis, it is able to adjust the angle of upper vehicle assembly relative to lower vehicle assembly and make sure the crawler fully contact the uneven ground and make the upper-vehicle assembly keep level. So that the crawler anchor drill rig will be more stable when it moves and travels on uneven ground. Moreover, the center of gravity of complete machine can be kept stable when the machine runs uphill and downhill in the condition of large gradient.

7. Rapid response capability in technological aspect

Yutong Heavy Industries has a strong R & D team, which can quickly and efficiently provide customized solutions according to the special needs of customers and create professional drilling equipment with medium and small bore diameters according to different demands of customers.
