CAT 307E2 Mini Crawler Excavator

The CAT 307E2 is a classic 7-ton class compact crawler excavator developed by Caterpillar, widely applied in municipal maintenance, landscaping, rural infrastructure construction, indoor demolition, and small-scale earthmoving projects. Renowned for its reliable performance, excellent fuel efficiency and flexible maneuverability, this model is a highly popular choice for small construction teams, rental fleets and urban engineering projects across global markets.

Powered by a Caterpillar C2.4 turbocharged diesel engine with a rated net power of 42.4kW (57hp), this excavator is matched with Caterpillar’s proprietary load-sensing hydraulic system, delivering precise and smooth control of the boom, arm and bucket with outstanding operational efficiency. It has an operating weight of approximately 7 tons and a standard bucket capacity of 0.28m³, featuring a zero-tail swing design that allows flexible operation in confined spaces such as urban streets and residential areas. The reinforced heavy-duty undercarriage with durable track chains ensures stable performance on rough terrain, while the fully enclosed, vibration-dampened cab provides excellent visibility and operating comfort for long working shifts.

To accommodate diverse procurement budgets and operational demands, we offer three condition options for all core large components: brand new, remanufactured, and refurbished. Key parts including the engine, main hydraulic pump, control valve, travel motors, swing motor, undercarriage frame and cab are all available in these configurations, enabling customers to select the most cost-effective solution tailored to their project needs, whether for new equipment purchase, fleet expansion or rental business deployment.

We provide comprehensive customization services for global buyers. The machine body can be painted in any custom color, with personalized logos, patterns or brand markings available upon request. A wide range of optional attachments such as hydraulic breakers, grapples, augers and various specification buckets are supported to expand the machine’s functionality for different working scenarios. Additionally, the control layout and hydraulic configuration can be adjusted to fit local operating habits and regional market requirements, ensuring strong adaptability to markets worldwide.
