The cylinder body utilizes forging instead of casting, effectively eliminating casting defects such as cracks and pores to enhance overall structural integrity. This results in superior strength and toughness, greatly extending operational service life.
In-house heat treatment furnaces ensure stable, batch-consistent quality. Every unit undergoes two strict operational tests pre-shipment. Robotic machining maintains tight manufacturing tolerances. With 95% of components self-manufactured, strict quality control enables seamless assembly for maximized power transmission.
Critical parts undergo normalization heat treatment. This optimizes grain structure for enhanced machining adaptability and long-term durability.
Consumables last significantly longer. Copper core components provide efficient heat dissipation, enabling 2,000-3,000-meter drilling without replacements.
The upgraded muffler design decreases operational noise levels, significantly improving worksite conditions and operator compliance.
Safe to use, fully pneumatic and can be deployed in closed environments without any risk of sparks.
Breaks rock and ore in excavation and tunnel construction with high-impact efficiency.
Demolishes concrete structures and breaks up road surfaces for maintenance and rebuilding.
Fragments large stones into manageable sizes for aggregate extraction and processing.
