1. Accurate Medium Pressure Adaptation & Wide Working Condition Coverage
Specially adapted to 0.8-1.0MPa mainstream industrial medium-pressure air compressors, it solves the problems of insufficient hard rock penetration and slow progress of low-pressure hammers, while avoiding the high energy consumption, high equipment investment and high operation cost of high-pressure hammers. It fits the conventional air pressure configuration of most outdoor engineering, mining and infrastructure sites, and can be used directly on the machine without equipment replacement, covering full-scene construction of small and medium-sized mines, pile foundations, blasting and water well drilling.
2. Large Piston Strong Impact & Outstanding Hard Rock Crushing Capacity
The upgraded large-diameter piston transmission structure features longer effective impact stroke, larger single impact energy and more concentrated force transmission, delivering far stronger penetration than ordinary 3-inch hammers for complex hard geology such as granite, hard sandstone and weathered hard rock. With a stable 16Hz high-frequency impact, it ensures uniform and efficient drilling without jumping, deviation or jamming, and maintains stable drilling speed even in soft and hard mixed rock layers, greatly improving construction efficiency in complex geological projects.
3. Central Exhaust Slag Discharge & Higher Hole Forming Quality
Adopting mature industrial central exhaust design, concentrated compressed air jet quickly flushes out rock slag, dust and gravel debris inside the hole, completely avoiding secondary rolling and crushing caused by slag accumulation. It effectively reduces drilling resistance and tool wear, ensures smooth hole walls and standard aperture, and eliminates hole collapse, blockage and position deviation. The high qualified rate of hole forming quality does not require secondary hole repair, saving labor and construction time and meeting the high-standard construction requirements of pile foundations and blasting holes.
4. Integral Forging Process & Greatly Improved Durability
The whole hammer is integrally forged from high-quality high-strength alloy steel, eliminating the loose defects of traditional casting technology. Combined with multiple high-temperature quenching and tempering hardening treatments, the internal and external hardness of the body is uniform with excellent toughness. It can resist long-term high-frequency impact, gravel friction, outdoor rain corrosion and temperature erosion, without cracking, deformation, air leakage and wear during long-term operation. The internal precision accessories have accurate matching gaps and smooth transmission with extremely low failure rate, enjoying longer service life than ordinary stamped and cast hammers.
5. Universal Lossless Adaptation & Convenient Replacement
Manufactured in strict accordance with international 3-inch DTH hammer universal standards, the outer diameter, interface, hole position and air channel dimensions are fully standardized, 100% compatible with all 3-inch medium-pressure DTH drilling rigs and 90-110mm full-series drill bits on the market. Old hammers with weak impact, slow drilling, frequent blockage and air leakage, and aging wear can be directly replaced without equipment modification or air pressure parameter debugging, plug and play, suitable for daily equipment maintenance, old equipment renovation and batch equipment supporting scenarios.
6. Balanced Energy Efficiency & Low Comprehensive Construction Cost
On the basis of super crushing performance, the air consumption is controlled at 7.2-10.5m³/min, with lower energy consumption and equipment load than heavy-duty high-pressure hammers, achieving significant energy-saving effects in long-term batch construction. It balances efficient drilling and energy saving, featuring low failure rate, long maintenance cycle and few replacements. It reduces comprehensive engineering construction costs from multiple dimensions including consumables, energy consumption, labor and construction period, becoming the most cost-effective choice for medium-end batch engineering construction.
