AT-2000 Opencast Raise-boring Machine Raise Boring Rig Reverse Counterboring
Main Features:
1. It adopts two-column and two-cylinder structure, which has good overall rigidity, high guiding precision and large bearing capacity. The rig frame is directly anchored to the foundation rock by installation. The gapless connection design of the base enables the rig to stabilize the operation without the support of the top support.
2. The rig adopts full hydraulic drive technology, its specially designed of high torque and infinitely adjustable features allow the rig to operate efficiently in hard rock.
3. The all-position working manipulator can complete the loading and unloading operation of the drill pipe in the whole process, saving staffing and reducing labor intensity.
4. The hydraulic system adopts an integrated design concept that simplifies the hydraulic piping structure with good stability, reliability and ease of maintenance.
