2. Power System

It is equipped with an original Japanese Isuzu 6HK1 electronically controlled common rail diesel engine, which has strong low-speed torque output, excellent overload resistance, and proven reliability after 20 years of global market verification.

Matched with SANY's self-developed intelligent power matching algorithm, the comprehensive fuel consumption is 8~10% lower than similar products of the same tonnage; the hourly fuel consumption under standard earthwork conditions is only 18~22L, greatly reducing user operating costs.
Equipped with multi-stage fuel filtration and high-temperature resistance protection system, it can adapt to harsh working environments such as high altitude, high temperature, and low-quality fuel in underdeveloped regions.

3. Hydraulic System

Adopts SANY's proprietary positive flow hydraulic control system, matched with imported Kawasaki main pump, main valve and travel motor core components:

Fast system response, fine operation accuracy, less than 0.3s lag of compound action, which can realize smooth coordinated operation of boom, arm, bucket and swing at the same time, and the operation efficiency is 12% higher than similar products.
Equipped with boom lowering energy recovery system and swing braking energy recovery system, which recovers redundant hydraulic energy to further reduce fuel loss.
The hydraulic oil filtration precision reaches 3μm, extending the hydraulic oil replacement interval to 5000 hours, reducing maintenance costs.

4. Structural Durability

The boom, arm and undercarriage key stress parts are made of high-strength wear-resistant steel plate, reinforced with thickened plates, and welded by full robot welding process. It has passed 10,000 hours of heavy-load fatigue test, and can adapt to harsh working conditions such as high-strength mining and hard rock excavation.
The heavy-duty undercarriage is equipped with reinforced track shoes, carrier rollers and idlers, with 30% longer service life than ordinary undercarriages.
The standard bucket is made of high manganese wear-resistant material, and optional attachments such as rock bucket, hydraulic breaker, grapple, auger and shear can be equipped to meet diversified operation needs.

5. Operator Comfort & Safety

The cab meets ROPS/FOPS international safety certification, with excellent anti-rollover and falling object impact protection performance.
Equipped with fully adjustable shock-absorbing seat, ergonomic multi-function control joystick (operating force ≤25N), which greatly reduces the fatigue of long-term operation.
Built-in automatic constant temperature air conditioning, 10-inch high-definition intelligent display, Bluetooth audio, USB charging port, and panoramic glass design provide 360° wide field of vision; the working noise inside the cab is only 72dB, reaching the level of passenger car quietness.

6. Intelligent Management & Easy Maintenance

Equipped with SANY SYMC intelligent control system, which supports real-time whole machine working status monitoring, fault self-diagnosis, and automatic maintenance reminder. Users can remotely check the equipment's operating data, location, fuel consumption and anti-theft status through the SANY IoT cloud platform, which is convenient for fleet management.
All daily maintenance points are arranged in ground-accessible positions, and the filter replacement interval is extended, reducing daily maintenance time by more than 30% compared with similar models.
SANY provides 3-year / 6000-hour long warranty for the whole machine (specific policy varies by region), and more than 10,000 after-sales service outlets around the world can provide 24-hour on-site service.

7. Typical Application Scenarios

Infrastructure construction: earthwork excavation and foundation construction for highways, railways, bridges, water conservancy projects
Mining and quarrying: ore stripping, hard rock excavation, gravel loading and unloading
Urban construction: old building demolition, underground space construction, municipal landscaping
Special operations: crushing, material handling, piling and other operations after matching corresponding attachments.

By 2024, the cumulative global sales of SANY 305 series excavators have exceeded 50,000 units, and it is widely recognized by users in more than 150 countries and regions for its high cost performance.
