Applications
This DTH hammer is widely used in metallurgy, coal, chemical industry, building materials, mining operations, and construction projects including highways, railroads, and national defense. It's suitable for dry, mixed wind and water, and wet operations with reliable performance.
Product Advantages
  • Improved design incorporating advanced technology
  • Constructed with superior alloy steel for durability
  • Extensive testing confirms longer service life
  • 15% higher penetration speed than conventional models
  • Lower air consumption for improved efficiency
Operating Principle
The DTH hammer operates through a precise pneumatic mechanism. During the impact stroke, compressed gas drives the piston downward at high speed to strike the drill bit. The system automatically reverses direction when the piston reaches the end of its stroke, creating a continuous hammering action.
