새니 SY 235

The Sany SY235 series represents the gold standard in the 23.5-tonne class excavator segment, combining robust performance, advanced technology, and exceptional fuel efficiency that have made it a preferred choice for contractors, construction firms, and mining operators worldwide. As Sany's flagship medium excavator, it excels in a diverse range of applications from general earthmoving and road construction to municipal engineering, real estate development, and small-scale mining operations, delivering consistent productivity and reliability in various working conditions. At the core of the SY235 series lies a choice of two powerful engine options: the Isuzu 4HK1 six-cylinder turbocharged diesel engine or the Cummins QSB6.7 engine, both delivering an impressive 128.5 kW (175 HP) at 2,100 rpm with displacements of 5.2 liters and 6.7 liters respectively. These advanced powerplants feature high-pressure common rail fuel injection systems that precisely control combustion for optimal efficiency and reduced emissions, while generating exceptional low-end torque for consistent performance under heavy loads. The SY235H national stage IV (Tier 4) variant incorporates an upgraded Isuzu 4HK1 engine with DOC+DPF+EGR after-treatment technology that eliminates the need for urea, simplifying maintenance while meeting strict emission standards. The SY235 series generates a maximum bucket breakout force of 158 kN (16.1 tonnes) and arm digging force of 118 kN (12.0 tonnes), enabling efficient excavation of compacted soil, gravel, and other challenging materials. With a standard bucket capacity ranging from 1.1 m³ to 1.35 m³ and maximum digging depth of 6,620 mm, it handles various excavation tasks with ease, while the 11.5 rpm swing speed ensures fast cycle times between digging and loading operations. The reinforced boom and arm structures with high-tensile steel provide exceptional durability, while the heavy-duty undercarriage with 7 track rollers per side ensures stability on uneven terrain. The SY235H model represents a significant advancement in excavator efficiency, incorporating a Kawasaki fully electronic positive flow hydraulic system that optimizes energy transfer and reduces fuel consumption by up to 8% compared to previous models. This advanced hydraulic system features electronic control valves, electronic joysticks, and an upgraded hydraulic controller that allows for adjustable spool valves, enabling operators to customize machine response to specific job requirements. Intelligent features include automatic idle and programmable auto-shutdown functions that further reduce fuel consumption during idle periods, while the multi-mode operation system allows switching between power and economy modes based on application needs. Built for operator comfort and productivity, the SY235 series features an ergonomic ROPS/FOPS certified cab with a low-noise design (75 dB), adjustable suspension seat, and intuitive controls that minimize fatigue during long work shifts. The spacious cabin with excellent 360° visibility enhances safety and efficiency, while the air conditioning system with positive pressure ensures a clean and comfortable working environment. The SY235 supports a wide range of attachments including hydraulic breakers, grapples, augers, thumbs, and rippers, expanding its versatility across multiple job site requirements.
