The HWX1000 Silenced Type Hydraulic Breaker is a medium-duty hydraulic rock breaker designed for excavators in the 11–16 ton range. It is engineered for high-impact Urban Demolition,Road Construction, Trenching and Quarrying. Unlike “Open” or “Side” type breakers, the silenced model is encased in a fully enclosed rectangular housing, which is the primary driver behind its popularity in modern urban construction.

Key Features
1. Advanced Noise Reduction
The “Silenced” designation comes from the Box Type housing.
The Shell Housing: A fully enclosed steel jacket prevents the direct escape of sound waves generated by the piston and chisel impact.
Acoustic Insulation: Internal hydraulic breaker shock absorber damping pads and sound-absorbing materials line the casing, reducing noise levels by up to 20 decibels compared to open models.
Urban Approval: This makes the HWX1000 the preferred choice for projects near hospitals, schools, and residential areas where strict noise ordinances apply.
2. Vibration Damping & Carrier Protection
The HWX1000 box type is designed with a floating suspension system.
Shock Absorbers: Heavy-duty rubber buffers and dampers are placed between the hammer body and the outer shell.
Lower Recoil: This system absorbs the high-frequency vibrations that would otherwise travel up the excavator boom, reducing “metal fatigue” and extending the life of your carrier machine.
3. Structural Durability (Box Housing)
Protection from Debris: The enclosed design acts as a shield, preventing dust, rocks, and debris from entering the internal hammer mechanism.
4. High Impact Efficiency
Gas-Hydraulic Power: It utilizes a nitrogen-charged accumulator (back head) to boost impact energy. The compressed gas assists the hydraulic oil to drive the piston with greater force than a hydraulic-only system.
Versatility: With a 100mm chisel, it is equally effective for primary rock breaking in quarries and secondary demolition of reinforced concrete.
Typical Applications
Urban Demolition: Safe for use in densely populated city centers.
Road Construction: Breaking up asphalt and reinforced concrete foundations.
Trenching: Excavating rocky terrain for pipelines and utilities.
Mining/Quarrying: Secondary breaking of boulders for easier transport.
