Every operational record is traceable, allowing global buyers to purchase with absolute confidence and zero worries.

Throughout its entire service cycle, this Sany 375 unit only engaged in standardized municipal engineering and conventional earthwork construction tasks, without long-term heavy-load mining, violent hard rock breaking, overloaded operation, or harsh environment abusive work. The equipment has always followed Sany’s official standardized maintenance specifications, with regular replacement of engine oil, hydraulic oil, fuel filters, and air filters. Scientific and standardized maintenance ensures uniform and mild wear of all core moving parts, effectively avoiding component aging, abnormal loss, and hidden mechanical faults caused by irregular maintenance.

This unit maintains excellent overall original condition with no major overhaul records, no core parts replacement, no structural welding repair, and no body deformation. The main frame, boom, arm, bucket, and chassis protective structures all retain original factory integrity, with no cracks, deformation, or repair traces. The ultra-low 1800-hour running-in state means the equipment has just completed the factory adaptive running-in period, and all power and hydraulic systems have reached the most stable working state, far superior to mid-hour and high-hour refurbished excavators in terms of service life, stability, and later maintenance costs.

Reliable Isuzu Power System: Strong Power & Energy-Saving Performance

The 2021 Sany 375 A29 is equipped with an authentic Isuzu 6HK1 high-efficiency diesel engine, the golden power configuration for Sany’s 37-ton heavy-duty excavators. This 6-cylinder large-displacement turbocharged engine delivers a maximum rated power of 212kW, with strong low-speed high-torque reserve and stable continuous power output. It boasts excellent explosive digging power and power sustainability, easily coping with hard soil excavation, medium-hard rock breaking, bulk material loading, and large-area earthwork stacking. Even under long-term full-load cyclic operation and complex harsh construction environments, the engine maintains sufficient power response without power attenuation, stalling, or insufficient digging force, fully meeting high-efficiency construction demands.

Adopting advanced high-pressure common rail fuel injection technology and optimized combustion structure, the Isuzu engine effectively improves fuel utilization efficiency and reduces invalid fuel consumption. Compared with traditional old-generation excavator engines, this power unit achieves prominent energy-saving effects while ensuring strong power output, greatly lowering long-term fleet operating costs and improving comprehensive economic benefits. The engine features stable operation, low vibration, and low noise, with excellent environmental adaptability, capable of stable operation in high-temperature, high-dust, and humid complex working environments for a long time.

Matched with the Isuzu power system is Sany’s upgraded intelligent load-sensing hydraulic system, the core high-efficiency configuration of the Sany 375 model. The high-flow main hydraulic pump and precise multi-way control valve realize adaptive flow distribution and dynamic pressure adjustment, making compound actions including boom lifting, arm stretching, bucket digging, and 360-degree slewing smoother, more sensitive, and more coordinated. The hydraulic system features fast response speed, low pressure loss, and stable pressure output, effectively shortening single-operation cycle time and significantly improving daily construction efficiency. It can perfectly meet the dual requirements of high-efficiency heavy-load excavation and precise fine leveling construction.

Reinforced Heavy-Duty Structure & Durable Chassis Performance

Tailored for long-term medium and high-intensity construction scenarios, the 2021 Sany 375 adopts an overall reinforced heavy-duty structural design. The thickened high-strength steel boom and arm undergo professional fatigue resistance and impact resistance treatment, with excellent compression resistance, deformation resistance, and structural stability. It can withstand long-term vibration, impact, and heavy-load pressure during rock breaking and earthwork operation, effectively avoiding structural cracking, fatigue damage, and deformation, greatly extending the service life of key working devices.

The whole machine retains the full original factory heavy-duty chassis system, including original thickened wear-resistant track shoes, reinforced track frames, heavy-duty support rollers, tension wheels, and high-torque travel motors. The optimized mining-grade chassis has ultra-high structural rigidity and excellent terrain adaptability. After 1800 hours of gentle standardized running-in, the chassis walking performance is more stable and flexible, with low vibration, no track deviation, and no abnormal walking noise. It can stably adapt to muddy construction sites, rugged gravel roads, mountain slopes, and complex quarry terrain, ensuring stable body posture during all-terrain operation.

Equipped with a standard 1.9m³ high-capacity original wear-resistant bucket, the machine has strong material penetration and loading capacity. The bucket parameters are precisely matched with the machine’s hydraulic output and digging force, with a maximum digging force of 235kN, ensuring efficient and stable material scooping and unloading. The original bucket has no wear deformation or structural damage, maintaining long-term stable working efficiency and avoiding efficiency attenuation caused by modified or mismatched accessories.

Humanized Cab & Intelligent Practical Configuration

The 2021 Sany 375 features a comfortable and safe fully enclosed silent cab, focusing on long-shift operation comfort and construction safety. The multi-layer sound insulation and dustproof structure effectively reduce internal operating noise and isolate external construction dust, creating a quiet and clean working environment for drivers. The panoramic wide-view window provides an ultra-wide field of view, eliminating construction blind spots and greatly improving overall operation safety.

The cab is equipped with complete humanized intelligent configurations, including a high-definition intelligent display screen, flexible integrated operating handles, adjustable suspension deluxe seat, and multi-functional charging interfaces. The optimized operating system reduces operating resistance and effectively relieves driver fatigue during long-term continuous work. The real-time intelligent monitoring system can display equipment operating data, fuel consumption, and fault information intuitively, facilitating daily equipment inspection and maintenance management for fleet managers.

In terms of daily maintenance, the machine adopts a convenient centralized low-position maintenance design. Core maintenance parts such as engine oil filters, fuel filters, and hydraulic detection ports are centrally arranged at low positions, realizing quick inspection, oil replacement, and filter replacement without climbing. This user-friendly design greatly saves daily maintenance time and labor costs, reduces equipment downtime, and effectively improves fleet operation attendance rate.
