The 20CrMo Forged Advantage
For mining operations in tough geological strata, durability is non-negotiable. Our SB151 power cell is forged from 20CrMo alloy steel, undergoing six-sided vacuum heat treatment to ensure maximum fatigue resistance. Unlike cast alternatives, our forged cylinders prevent micro-fractures under the intense 230 Bar working pressures required to break high-density quartz and limestone.
HWX1750 (SB151) hydraulic demolition hammer is essential construction machinery attachment. It can be used as mining device, quarry hydraulic hammer and concrete machinery. This silent box type hydraulic breaker features a monolithic, box-shaped housing and is top-mounted, making it suitable for top-mounting on excavators for crushing operations. Its long overall length allows for a long crushing distance. The fully enclosed housing incorporates internal noise reduction features, such as MIC shock absorption technology and high-tech special materials, to effectively reduce noise transmission. It utilizes an advanced hydraulic system and is constructed from high-strength alloy materials. Its specialized design and high-quality manufacturing process ensure excellent wear and corrosion resistance, enabling long-term, stable operation in high-intensity operating environments.
Operational Outcome: The SB151 delivered a consistent 35-45 m³ per hour production rate, maintaining 100% impact energy throughout 10-hour daily shifts.
Client Review: “The noise reduction of the Silenced Box housing is compliant with strict EU urban regulations, while the striking force rivals Tier-1 global brands.”
