三一重工 SY 335

The Sany SY335 series stands as a cornerstone of Sany’s medium excavator lineup, delivering exceptional performance, reliability, and efficiency for 33-35 tonne class applications worldwide. As a versatile workhorse trusted by contractors, mining operators, and construction companies, it excels in a wide range of tasks from large-scale earthmoving and foundation digging to road construction and quarry operations, combining robust engineering with intelligent technology to maximize productivity while minimizing operational costs. At the heart of the SY335C lies the powerful Isuzu 6HK1 six-cylinder turbocharged diesel engine, available in 190.5 kW (256 HP) or 210 kW (282 HP) configurations at 1,900 rpm. This engine features advanced combustion technology, delivering strong low-end torque for consistent performance under heavy loads, while maintaining fuel efficiency through optimized fuel injection and cooling systems. The SY335BH-S variant further enhances efficiency with a VGT (Variable Geometry Turbocharger) that reduces response time and minimizes fuel loss during transient operations. Paired with a full-power variable displacement hydraulic system and load-sensing control, the SY335 delivers precise, responsive operation with minimal energy waste. The system generates a maximum bucket breakout force of 220 kN (22.4 tonnes) and arm digging force of 170 kN (17.3 tonnes), enabling efficient excavation of hard soil, rock, and other challenging materials. With a standard bucket capacity of 1.5 m³ (2.0 m³ for earthmoving-focused models) and maximum digging depth of 7,100 mm, it handles medium to deep excavation tasks with ease, while the 9.5 rpm swing speed ensures quick cycle times between digging and loadingSANY. Built for durability, the SY335 features reinforced boom and arm structures, heavy-duty undercarriage components, and wear-resistant materials in high-stress areas, ensuring reliable operation in harsh working environments. The LC (Long Track) version offers enhanced stability and reduced ground pressure, making it suitable for soft terrain and large load-lifting applications. Intelligent features include Sany’s advanced monitoring system, which provides real-time data on engine performance, fuel consumption, and maintenance alerts, helping operators optimize efficiency and prevent downtime. Operator comfort is prioritized with an ergonomic cab featuring ROPS/FOPS certification, low-noise design, and intuitive controls. Automatic idle and programmable auto-shutdown functions further reduce fuel consumption during idle periods, while the spacious cabin with excellent visibility minimizes fatigue during long work shifts. The SY335 also supports a wide range of attachments, including breakers, grapples, and augers, expanding its versatility across multiple job site requirements. With its combination of powerful performance, fuel efficiency, and durability, the Sany SY335 series has established itself as a competitive choice in the global medium excavator market, offering exceptional value for contractors seeking a reliable and productive machine for their mid-sized projects.
