Key Performance Advantages

1. High-Efficiency & Fuel-Saving Power System

The electronically controlled high-pressure common rail fuel injection system matches the optimized turbocharging design, delivering high torque at low rpm, adapting to heavy-load construction under extreme temperatures and high altitude conditions.
Equipped with an optional ECO energy-saving mode, which reduces unnecessary power output under light-load conditions, and the comprehensive fuel efficiency is 10% higher than the previous generation 307D model. The 3-level fuel filtration system has strong tolerance to low-quality construction site diesel, reducing the risk of engine failure.

2. Precise & Smooth Hydraulic Performance

Adopts Caterpillar’s proprietary load-sensing hydraulic control technology, which realizes smooth coordination of compound actions (simultaneous digging, swinging and lifting) with zero lag, and the operation accuracy meets the requirements of fine construction such as pipeline trenching and landscaping.
The boom and stick are designed with hydraulic regeneration function, which reduces the load of the main pump during operation, not only reduces fuel consumption, but also improves the speed of action, and the breaking force when matching hydraulic breakers is 15% higher than similar products of the same level.

3. Ultra-Durable Structural Design

The boom, stick and X-type chassis frame are made of high-strength wear-resistant steel, and all welded joints are subjected to stress relief treatment, which can withstand long-term heavy-load impact.
Users can choose steel tracks (for rough construction sites) or rubber tracks (for urban road operations, no damage to the pavement), and the standard bucket is equipped with replaceable wear-resistant teeth and side cutters, which greatly extends the service life of wearing parts.

Operator Comfort & Safety

The cab is certified with ROPS (Roll Over Protective Structure) and FOPS (Falling Object Protective Structure), which fully guarantees the personal safety of operators in case of accidents.
The fully sealed cab has sound insulation and heat insulation design, the internal operating noise is as low as 75 dB, the adjustable suspension seat and low-effort pilot joystick greatly reduce the fatigue of long-term operation.
The large-area panoramic glass provides a 270° wide field of view, and the blind area of the working device and chassis is minimized. The high-definition LCD instrument panel displays real-time data such as fuel consumption, water temperature and fault codes in real time, which is convenient for operators to grasp the equipment status.
Standard configurations include travel alarm, swing alarm, emergency stop button and multi-port air conditioning system, and optional USB charging port, heating function and anti-theft system are supported.

Low Operating & Maintenance Cost

The maintenance interval is greatly extended: engine oil and filter replacement interval is 500 hours, hydraulic oil replacement interval is 2000 hours, air filter and hydraulic return filter replacement interval is 1000 hours, which effectively reduces the downtime caused by maintenance.
All daily maintenance points are arranged on the side of the body, which can be accessed and operated directly on the ground, no need to climb the car, which improves the convenience of daily inspection.
Caterpillar’s global after-sales service network provides timely parts supply and technical support, and the residual value of used 307E2 excavators is 15-20% higher than similar products of other brands, which reduces the comprehensive use cost for users.

Optional Attachments & Application Scenarios

Common Optional Attachments

Quick coupler, hydraulic breaker, auger, wood grabber, clamshell bucket, ripper, etc.

Typical Application Scenarios

Urban municipal pipeline trenching, landscaping shaping, rural self-built house foundation excavation, small water conservancy channel dredging, small building demolition, site leveling, material loading and unloading, etc. It is the preferred equipment for small and medium-sized engineering contractors to improve construction efficiency.
