PRODUCT OVERVIEW
HD250 Top Drive Rotary Power Head is a high-end component engineered for extreme drilling conditions such as ultra-hard rock and large cobble beds. As the core power unit of engineering drilling rigs, it integrates high impact energy, high torque and high-frequency percussion, thoroughly resolving industry pain points including slow penetration, insufficient torque and excessive wear of conventional equipment in ultra-hard formations. Fitted with internationally renowned hydraulic motors, multiple high-pressure accumulators and an intelligent reverse percussion mechanism, it is suitable for full-scenario construction including foundation reinforcement, geothermal drilling and tunnel advance support.
{Integrates high impact energy, high torque and high-frequency percussion, easily conquers ultra-hard rock, coarse gravel layers and cobble beds, doubling drilling efficiency in complex conditions.}
{Multi-speed torque and speed settings for flexible configuration to construction needs, covering both light and heavy drilling scenarios with one unit.}
{Multiple high-pressure accumulators ensure stable energy storage and pressure, delivering consistent impact power without attenuation and greatly reducing failure rate.}
{High-performance backstroke device enables quick rod lifting during sticking, effectively reducing tool wear and downtime.}
{Adapts to wide temperature ranges, performing reliably regardless of climate variations on site.}
{Equipped with world-renowned orbital motors for smooth power output, low failure rate and reliable long-hour continuous operation.}
{Standardized interfaces with genuine spare parts and technical support, minimizing maintenance costs.}
