How to choose hydraulic breaker for excavator

In order for hydraulic breaker ‘s performance efficiency, extend the life , usually it should be consider the excvator specification and breaker ‘s output flow in back-up valve and pressure, etc

To Match of hydraulic breaker and excavator
it can be calculated by below formula

0.3 ≤ R · Wb / S · We ≤ 0.5

R – maximum breaking radius (mm)

S – half of the excavator track (mm)

Wb – breaker weight (kg)

We – Excavator Weight (kg)

On the calculated ratio is less than 0.3, that mean the breaker you choose is smaller, the breaker can easily be damaged; if the ratio is greater than 0.5, that mean breaker is bigger

In addition, we also consider the size of the connection between the breaker and excavator working device, and coordination of the hole, appropriate shaft ;hydraulic breaker required flow and pressure must be consistent with Excavator spare valve output flow and pressure
