The CAT 305 CR is a crawler mini excavator of 5.5–5.8 t. For this weight we recommend the Promove XP300 hydraulic breaker: the machine sits in the lower part of the optimal range (4.5–8 t) of the XP300. Anything beyond the weight class is confirmed individually with your machine data.
According to CAT, the operating weight is about 5.5 t, and up to about 5.8 t in the heaviest EU configuration. Predecessors and variants such as the 305E2 CR are close in weight, but are checked separately.
Does the Promove XP300 fit the CAT 305 CR?
| Criterion | CAT 305 CR (according to CAT) | Promove XP300 (according to Promove) | Assessment |
|---|---|---|---|
| Operating weight | 5.5–5.8 t | 4–9 t, optimal 4.5–8 t | ✓ inside the carrier class |
| Auxiliary flow | depends on configuration | 50–60 l/min | confirmed with your machine data |
| Pressure / relief valve | depends on configuration | operating 110–130 bar, relief valve on the excavator 180 bar | relief valve setting confirmed with your machine data |
| Return line | direct return to tank: please check | max. back pressure 25 bar | confirmed with your machine data |
| Quick coupler | type on your machine: please check | bolted top plate; quick coupler not included | send us the coupler type |
Machine data according to the manufacturer; values vary with equipment and year of build. Auxiliary flow and pressure are not stated here – we confirm it with your machine data before we quote.
Why the XP300 for the CAT 305 CR
The XP300 is built for carriers of 4–9 t and runs on 50–60 l/min at 110–130 bar with a tool diameter of 80 mm and a working weight of 300 kg. Matching breaker weight to machine weight keeps the CAT 305 CR stable and protects boom and pins; matching oil flow keeps the blow rate in the range Promove specifies. More machines in this class: breakers for 4–9 t excavators.
The Promove XP400 (5.5–10 t, 70–80 l/min) is the heavier option. It only makes sense if the auxiliary circuit of your CAT 305 CR really delivers 70–80 l/min and you mainly break hard material; on lighter configurations the XP300 is the better match.
Fit notes
- Oil flow: if the auxiliary circuit delivers more than 50–60 l/min, it is limited on the machine.
- Relief valve: set to 180 bar for the XP300.
- Return: a direct return to tank keeps back pressure below 25 bar.
- Each point is settled with your machine data before we quote.
