Business Solution Overview
Built for Demanding Site Conditions: All structural parts are reinforced for various work conditions, helping the rig withstand the stresses of surface rock drilling and supporting longer service life in tough operating environments.
Improved Drilling Efficiency: The own rotation unit driven by double cycloid motor is designed for more powerful rotation and less drill tool jamming. Higher torque capability supports effective drilling across the stated hole diameter range.
Better Site Mobility: A plunger piston tramming motor, box-type tramming beam, and crawler tracks support stronger climbability and dependable movement on uneven ground, which is important for active quarry and blast hole drilling sites.
Lower Dust Impact on Operations: The own developed dry dust collection system is described as high efficiency and more eco-friendly. This can help create a cleaner drilling environment and support more controlled surface operations.
Maintenance-Friendly Design: The new enclosure design is intended to make maintenance and service more convenient. Easier access can help reduce downtime during routine inspection and upkeep.
