HD-120X

HD-120X Top Drive Rotary Power Head integrates ultra-high torque, 4-speed adjustment and high impact energy, addressing core industry pain points such as slow drilling, insufficient torque, limited working condition adaptability and stuck drill difficulty in hard rock, gravel and cobble layers. Equipped with world-renowned orbital motors, multiple high-pressure accumulators and an intelligent reverse percussion device, it is suitable for construction scenarios including underground micro-piles, anchor cables, deep foundation pit reinforcement, tunnel advance support and geothermal drilling.

• •Four-speed rotation combined with four torque ranges enables high torque at low speed for hard rock drilling and high efficiency at high speed for soft formations, delivering full-formation adaptability with one machine
• •Automatic reverse-impact function strikes the drill string during stuck-pipe conditions for rapid recovery, reducing tool wear and downtime risk
• •High impact energy combined with high-frequency percussion ensures fast penetration in hard rock, gravel, and cobble formations, significantly improving drilling efficiency
• •Equipped with internationally renowned cycloidal motors for smooth power output, low failure rate, and reliable long-duration continuous operation
• •Designed for wide temperature range operation, maintaining stable performance in diverse climatic and jobsite conditions
• •Standardized interfaces with OEM spare parts supply and technical support help reduce maintenance costs and improve service efficiency
