Key Features

Carrier Compatibility: Ideally suited for 20-ton class excavators (e.g., Komatsu PC200, Cat 320, Hitachi ZX200).
Internal Accumulator: The SD220 typically features an optional accumulator (unlike larger models where it is standard) to protect the carrier’s hydraulic system from pressure spikes.

Silenced Design (S-Type): The “S” model uses a fully enclosed box housing with damping elements to reduce noise levels and vibration transfer to the excavator.

Auto Shut-Off: Designed to prevent “blank firing,” which protects the internal piston and chisel from unnecessary wear when the tool is not in contact with the material.

Note: These specifications are based on standard manufacturer data. If you are mounting this to a specific excavator model, ensure your machine’s hydraulic flow and pressure settings are adjusted to match the “Required Oil Flow” (130–170 L/min) to avoid overheating or damage.
