Promove XP300 Hydraulic Breaker · 4–9 t excavators
Hydraulic breaker for JCB 55Z-1
The JCB 55Z-1 is a zero-tail excavator with an operating weight of 4.79–5.48 t (ISO 6016, depending on equipment). It sits in the optimal range of the Promove XP300 (4.5–8 t). JCB fits it with programmable auxiliary lines and several selectable flow stages, a good starting point for a breaker.
The deciding question is whether a stage within the XP300's range (50–60 l/min) can be selected. JCB's published data leaves this open for the middle range. Fit is checked before payment.

Frequently asked questions
Which flow stage should I select for the XP300?
A stage between 50 and 60 l/min. Whether your 55Z-1 has such a stage, we check with your details before you pay.
What do you need to know about my 55Z-1?
Serial number or year of build, your quick coupler and, if available, dealer information or a measurement of auxiliary flow. That tells us how your machine is equipped.
Does the breaker also fit the JCB 48Z-1?
The 48Z-1 is lighter. Whether the XP200 or XP300 suits it better depends on your machine's weight and hydraulics. We are happy to advise.
How do I pay?
By SEPA bank transfer against a proforma invoice or by card, in both cases only after fit and VAT number are confirmed.
