|---|---|---|---|
| Applicable Carrier Weight | ton | Recommended excavator or carrier operating weight range. | Ensures correct match between breaker and machine; affects stability and efficiency. |
| Operating Weight of Breaker | kg | Total weight including bracket and tool. | Affects transport, carrier balance and working condition. |
| Oil Flow (Required) | L/min (GPM) | Hydraulic oil volume needed for optimal operation. | Must match carrier’s auxiliary hydraulic circuit; too low or high flow will reduce performance or cause damage. |
| Operating Pressure | bar (psi) | Hydraulic pressure range needed to drive the piston. | Carrier system must provide compatible pressure; mismatch leads to inefficient or unsafe operation. |
| Back Pressure (Max) | bar (psi) | Maximum return line pressure acceptable to the breaker. | Helps evaluate compatibility with carrier hydraulic return line. |
| Impact Rate / Blow Frequency | bpm (blows per minute) | Number of blows per minute at rated flow and pressure. | Higher frequency is generally better for softer materials; lower frequency with higher energy per blow is better for hard rock. |
| Impact Energy (Theoretical) | Joule (J) | Energy per blow, sometimes given as an indicative value. | Rough measure of breaking power; actual performance also depends on tool, material and operator technique. |
| Tool Diameter | mm | Diameter of the working tool (chisel, moil, etc.). | Often correlates with breaker size and impact energy; larger diameter usually means heavier-duty applications. |
| Hose Size | inch | Recommended diameter of inlet and return hoses. | Correct size ensures proper flow, reduces heat and pressure loss. |
| Noise Level (if available) | dB(A) | Sound pressure level during operation. | Important for urban and regulated sites; box type breakers often have lower noise. |
The following table provides indicative ranges for common hydraulic breaker size categories. Actual values differ between manufacturers and models, but this overview can help buyers identify rough ranges when sourcing from global suppliers and exporters.
| Size Category | Carrier Weight Range (ton) | Breaker Operating Weight (kg) | Required Oil Flow (L/min) | Operating Pressure (bar) | Impact Rate (bpm) | Tool Diameter (mm) |
|---|---|---|---|---|---|---|
