2. Power System

The 307E2 is equipped with a self-developed Cat C2.4 DI turbocharged 4-cylinder diesel engine, tailored for complex construction scenarios:

Adopts high-pressure direct injection technology, delivering high torque at low RPM to cope with heavy-load operations smoothly, and meets regional emission standards including China Stage III, EPA Tier 4 Interim and EU Stage IIIA for different target markets.
Built-in auto-idle and optional ECO mode reduce fuel consumption by 10%~15% under light-load conditions, significantly cutting daily operating costs.
3-stage fuel filtration system adapts to low-quality fuel in remote construction sites, reducing engine failure risks. The rated service life of the engine exceeds 10,000 working hours under regular maintenance.

3. Hydraulic System

It adopts Caterpillar’s proprietary load-sensing hydraulic system, ensuring precise and smooth operation:

The main pump delivers a maximum flow of 140 L/min, supporting stable compound movements (e.g. simultaneous digging, swinging and traveling) without lag.
Equipped with stick regeneration and boom priority functions, reducing hydraulic energy loss and improving operation efficiency by 8% compared to same-class competitors.
The hydraulic oil replacement cycle reaches 5,000 working hours, lowering long-term maintenance costs.
Supports quick coupler for fast switching of attachments, including breakers, grapples, augers and rippers, to adapt to diverse work demands.

4. Structural Durability

The 307E2 is designed for high-impact, high-frequency construction scenarios:

The heavy-duty X-type undercarriage is welded with high-strength steel, with reinforced rollers, idlers and track chains, with a wear life 20% longer than industry average.
The boom and stick are added with reinforced rib plates at high-stress points, passing 10,000 hours of fatigue testing under extreme heavy-load conditions.
Optional boom offset function (left/right swing by 70°/55°) supports operation in narrow spaces such as along walls, indoors or in basement construction sites.

5. Operator Experience

The ROPS/FOPS certified enclosed cab is designed to reduce fatigue during long-hour operations:

Fully sealed and pressurized cab reduces dust ingress and cuts internal noise to 78 dB(A) only, reaching industry-leading low noise level.
Adjustable suspension seat, ergonomic pilot control joysticks with low operating force, and high-performance air conditioning system improve comfort in extreme cold/hot environments.
Full-color LCD monitor displays real-time operating data, fault alarms and maintenance reminders, supporting multiple language switching for global users. It is also equipped with storage compartments, cup holders and USB charging ports for daily use.

6. Safety & Maintenance Convenience

Standard travel alarm, swing alarm, anti-slip walking platform and emergency stop button reduce operation risks; optional rearview camera eliminates blind spots during reversing and swinging.
All daily maintenance points (oil filters, fuel filters, air filter, lubrication points) are accessible from the ground without climbing on the machine, cutting daily inspection time by 50%.
Standard Caterpillar Product Link™ remote monitoring system supports real-time tracking of working hours, fuel consumption, location and fault warnings, making it easy for fleet managers to realize digital management.

7. Typical Application Scenarios

The 307E2 is suitable for a wide range of operation scenarios:

Municipal engineering: trench digging, pipe laying, road maintenance
Landscape and gardening: land leveling, tree planting, pond excavation
Building construction: foundation digging, material transfer, small-scale demolition
Agricultural work: farmland renovation, irrigation ditch digging, greenhouse construction
Narrow-space operations: indoor demolition, basement construction, urban renewal projects

Supported by Caterpillar’s global after-sales network, 24/7 technical support and genuine parts supply, the 307E2 also has industry-leading residual value, making it a cost-effective choice for small and medium-sized construction participants.
