2. Performance & Operation Efficiency

Advanced hydraulic system: Equipped with Cat load-sensing flow-sharing hydraulic system, which ensures smooth and synchronous control of multiple actions (digging, swinging, traveling) at the same time, with no lag even under heavy load, greatly improving operation accuracy.
Low fuel consumption: Two working modes are available: Standard Mode balances power and fuel consumption for daily light and medium duty, reducing fuel use by 8-10% compared with the previous generation 307D; Power Mode delivers full power for hard soil excavation, breaking and other heavy-load scenarios. The automatic idle and auto-shutdown functions further reduce unnecessary fuel waste during standby.
High attachment compatibility: It supports optional auxiliary hydraulic circuits, and can be matched with a variety of attachments including hydraulic breakers, grapples, augers, rippers, and quick couplers to adapt to diversified operation demands.

3. Operator Comfort

The cab adopts pressurized sealing design, with internal operating noise as low as 75 dB(A), effectively isolating dust and external noise.
Equipped with fully adjustable suspension seat, ergonomic low-effort pilot control joysticks and adjustable travel pedals, which reduce operator fatigue during long-hour work.
Full-coverage glass window and skylight provide 360° dead-angle-free visibility, ensuring operation safety in narrow spaces. The high-definition color LCD monitor displays real-time data including fuel level, water temperature, fault code and operating hours in real time.
Standard air conditioning/heating system, USB charging port, and storage compartment for tools and personal items further improve operating experience.

4. Durability & Maintainability

The boom, arm and main frame are made of high-strength wear-resistant steel, after strict stress and impact tests, which can adapt to long-term harsh working conditions. The heavy-duty undercarriage supports optional reinforced steel tracks or rubber tracks, and all rollers and idlers adopt sealed lubrication design, extending service life by 30% compared with ordinary products.
All daily maintenance points (oil filter, fuel filter, air filter, hydraulic oil filter) are designed to be accessible from the ground, eliminating the need to climb onto the machine, and cutting daily maintenance time by more than 40%.
With Cat genuine lubricants, the hydraulic oil replacement interval reaches 5,000 hours, and the engine oil replacement interval is 500 hours, which reduces long-term use costs. Optional Cat Product Link™ remote monitoring system supports real-time tracking of equipment location, fuel consumption, operating hours and fault alarms, which is convenient for fleet management.

5. Safety Design

The cab is certified by ROPS (Roll-Over Protective Structure) and FOPS (Falling Object Protective Structure), which effectively protects the safety of operators in case of rollover or falling objects.
Equipped with swing warning buzzer, travel warning light, and hydraulic safety lock lever (all operations are disabled when the lock lever is lifted to avoid misoperation). The non-slip walking platform ensures safe access to the machine even in rainy and snowy weather, and the emergency descent function allows the work device to be safely retracted even if the engine stops accidentally.

6. Typical Application Scenarios

The 307E2 is widely used in:

Municipal engineering: trench digging, pipeline laying, sidewalk maintenance
Landscape construction: tree pit digging, site leveling, vegetation transplanting
Rural construction: house foundation excavation, irrigation and water conservancy construction, rural road repair
Small demolition, material handling, indoor renovation and other narrow-space operationsIt has high residual value, and Cat’s global after-sales service network and sufficient spare parts supply further reduce the use cost for end users.
