HDL series top-drive multi-functional drilling rigs are developed in response to market demand and are designed to operate efficiently in complex geological conditions.

• High-power top-drive rotary head enables impact drilling without the need for down-the-hole hammers or air compressors
• A high-stability variable-angle mechanism combined with a vertical rotary table allows flexible multi-angle adjustment, making the rig particularly suitable for tunnel construction
• Drilling tools transmit impact energy evenly from the outer to the inner structure, reducing risks such as rod sticking and hole collapse, thereby lowering construction costs and risks
• Delivers high torque, high rotational speed, and strong power output, enabling rapid drilling in gravel, fractured rock, cobble layers, and sandy strata while ensuring borehole quality
• Dual-power rotary head design allows forward and reverse rotation of casing and drill rods at different speeds
