Overview
The 5–10 ton excavator class is one of the most versatile in construction — large enough for meaningful productivity, compact enough for urban and semi-confined applications. This class is widely used in road construction, utility work, foundation preparation, and general civil engineering.
For this class, the SB30 (200–260 kg, 400–600 J) is the primary recommendation for the lower end (5–7 ton), while the SB40 (320–400 kg, 600–900 J) is better suited for the upper end (7–10 ton). The choice between them depends on the primary application — the SB30 for lighter work and the SB40 for harder rock and more demanding demolition.
The 5–10 ton class typically provides 45–90 L/min of auxiliary hydraulic flow, which is sufficient for both the SB30 and SB40. However, it is essential to verify the specific flow and pressure specifications of your excavator model before selecting a breaker.
Recommended Models
Hydraulic Requirements
| Excavator Class | 5–10 ton |
| Oil Flow Required | 45–90 L/min |
| Working Pressure | 120–170 bar |
| Recommended Models | SB30, SB40 |
Common Compatible Excavators
* Always verify hydraulic flow and pressure specifications for your specific machine model before purchasing.
Common Selection Mistakes
Using an SB40 on a 5-ton machine — the weight and flow requirements may exceed the machine's capacity
Selecting based on price alone without checking hydraulic compatibility
Ignoring the back pressure specification — excessive back pressure reduces performance significantly
Selection & Efficiency Tips
For 5–7 ton machines, the SB30 is the safer choice — it won't overload the front linkage
For 8–10 ton machines, the SB40 provides significantly better productivity in hard rock
Always check the excavator's auxiliary circuit relief valve setting before operation
