1. Flagship High Pressure Adaptation for Super Large Aperture Heavy Loads
Precisely adapted to 1.05-1.25MPa high-power industrial high-pressure air systems, it is professionally developed for super-large diameter, ultra-deep hole and ultra-hard rock heavy-load scenarios that cannot be undertaken by 4-inch and smaller drills. It perfectly solves core problems such as insufficient large-diameter drilling power, deep-hole speed drop, difficult hard rock penetration and large slag blockage. Compatible with high-end complete high-pressure equipment of super-large mines and national heavy infrastructure, it can be directly operated at full heavy load without equipment modification. As an exclusive flagship device for super-large diameter heavy-duty drilling projects, it has irreplaceable performance and market advantages.
2. Ultra-Large Stroke Piston & Constant Deep-Hole Power
Adopting the top-tier ultra-large stroke heavy-duty piston structure in the industry, the effective impact stroke, single impact energy and force transmission area are fully upgraded with far sufficient impact reserve than ordinary 5-inch hammers. It maintains full-power output in ultra-deep holes without power attenuation, slipping or stagnation, specially conquering high-difficulty geology such as dense granite, ultra-hard rock and complex mixed rock layers. With a stable 16Hz high-frequency and high-torque impact, it realizes uniform and thorough rock breaking for super-large apertures, improving construction efficiency by more than 40% compared with ordinary large-size hammers and greatly shortening the construction period of super-large mine blasting projects.
3. Full-Flow Central Slag Discharge & Zero Blockage for Large Apertures
Customized full-flow super-large channel central exhaust system for 130-150mm super-large diameter construction features greatly increased high-pressure air flow and dead-angle-free jet coverage, which instantly removes a large number of large hard rock debris, gravel and dust in super-large holes. It completely eliminates common faults in large-diameter deep-hole construction such as slag accumulation, secondary crushing, jamming, hole collapse and irregular hole forming. The smooth and standard hole wall requires no secondary manual repair, fully meeting the high-precision and high-standard forming requirements of large mine deep-hole blasting and super pile foundation projects, and greatly reducing heavy-load construction failure rate and labor cost.
4. Military-Grade Integral Forging & Ultra-Long Fatigue Resistance
The whole hammer is integrally forged from military-grade ultra-high-strength alloy steel with dense and uniform structure, no casting pores, looseness or cracks. After multiple high-temperature quenching and tempering heavy-duty reinforcement heat treatments, its body hardness, core toughness, impact resistance and fatigue resistance reach the industry’s top level. It resists 24-hour uninterrupted ultra-high-frequency heavy-load impact, severe friction of large hard rock and erosion of humid and complex deep well environments without deformation, air leakage, wear or cracking during long-term use. Internal core accessories are precisely matched with zero transmission jamming and zero power loss, enjoying far longer service life than ordinary large-size hammers and adapting to year-round uninterrupted continuous production of super-large mines.
5. Standard Flagship Specification & Lossless Quick Replacement
Manufactured in strict accordance with international high-end general standards for 5-inch high-pressure DTH hammers, all outer diameter, connecting thread, air channel and sealing dimensions are fully standardized, 100% compatible with all brands of 5-inch high-pressure heavy-duty rigs and 130-150mm full-series super-large diameter drill bits on the market. Old 5-inch hammers with deep-hole power attenuation, insufficient large-diameter rock breaking power, frequent blockage and air leakage, body fatigue aging and low construction efficiency can be directly replaced without air pressure debugging and equipment modification, plug and play, suitable for batch maintenance of super-large mines, high-end equipment renovation and foreign trade flagship tool supporting.
6. Heavy-Duty High Efficiency & Low Total Project Cost
Scientifically matched with 12-16m³/min large flow air consumption for super-large diameter deep-hole heavy-load working conditions, it achieves extreme wind pressure energy utilization without invalid energy waste, perfectly adapting to stable output of large industrial air compressors. It features extremely stable heavy-load operation, ultra-low failure rate, super-long maintenance cycle and minimal accessory loss, greatly reducing equipment downtime maintenance time and replacement cost. For batch deep-hole blasting and super-large diameter pile foundation construction of super-large mines, it delivers higher comprehensive construction efficiency and lower operation cost, serving as a flagship core equipment with balanced performance and cost performance for high-end heavy-duty projects.
