Product Introduction
Precision-Engineered HWX680 Hydraulic Rock Breakers are optimized for the high-frequency demands of 4-7 ton class excavators. Built on the proven Soosan SB40 system, the HWX680 delivers industry-leading 110-140 kg/cm² impact energy. Whether you are operating a Komatsu PC60-8, Sany SY60C, or Hitachi ZX60-5A, our custom-fit mounting brackets ensure a 100% plug-and-play experience for demolition, trenching, and landscaping.
Forged 20CrMo Cylinder & Core: Unlike standard cast bodies, the HWX680 cylinder is made from forged 20CrMo alloy steel, undergoing rigorous vacuum heat treatment and cryogenic processing to ensure maximum hardness (HRC 58-62) and anti-wear properties.
100% Soosan SB40 Compatibility: Every internal part—from the piston to the through-bolts—is interchangeable with Soosan SB40 components, resolving any global spare parts sourcing concerns.
Vibration Damping System: Equipped with high-density polyurethane shock absorbers that protect your carrier’s boom (especially on 60-series machines) from fatigue cracking during long-shift operations.

1. Powerful Impact
The synergistic effect of hydraulics and nitrogen creates a powerful hydraulic hammer.
2. Durability
Our excavator hydraulic breaker is made of high-quality materials and precision craftsmanship, the cylinder and piston undergo extensive heat treatment, secondary heat treatment, and cryogenic treatment, significantly extending the life of the machine.
3. Quiet and Vibration-Improving
The finely polished cylinder and piston, combined with strategically installed hydraulic breaker shock absorbers, effectively reduce friction, noise, and vibration damping.
4. Convenient Operation
The fully hydraulic drive system ensures smooth reciprocating motion and minimizes backlash.
5. High-Quality Packaging
Products are packaged in wooden boxes, fully sealed with plastic for safe and rust-proof transportation.
