The CAT 302.7 CR is a crawler mini excavator of 2.7–3.0 t. For this weight we recommend the Promove XP151 hydraulic breaker: the machine sits well inside the optimal range (2.2–3.6 t) of the XP151. Anything beyond the weight class is confirmed individually with your machine data.
According to CAT, the operating weight is about 2.7 to 2.8 t on the CE plate and up to about 3.05 t in the heaviest configuration. Predecessors and variants such as the 302.7D CR are close in weight, but are checked separately.
Does the Promove XP151 fit the CAT 302.7 CR?
| Criterion | CAT 302.7 CR (according to CAT) | Promove XP151 (according to Promove) | Assessment |
|---|---|---|---|
| Operating weight | 2.7–3.0 t | 1.8–4 t, optimal 2.2–3.6 t | ✓ inside the carrier class |
| Auxiliary flow | depends on configuration | 25–35 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 XP151 for the CAT 302.7 CR
The XP151 is built for carriers of 1.8–4 t and runs on 25–35 l/min at 110–130 bar with a tool diameter of 52 mm and a working weight of 165 kg. Matching breaker weight to machine weight keeps the CAT 302.7 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 2.5–5 t excavators.
The Promove XP200 (2.5–5.2 t, 40–60 l/min) is the heavier option. It only makes sense if the auxiliary circuit of your CAT 302.7 CR really delivers 40–60 l/min and you mainly break hard material; on lighter configurations the XP151 is the better match.
Fit notes
- Oil flow: if the auxiliary circuit delivers more than 25–35 l/min, it is limited on the machine.
- Relief valve: set to 180 bar for the XP151.
- Return: a direct return to tank keeps back pressure below 25 bar.
- Each point is settled with your machine data before we quote.
