The SY35U from SANY is a 3.8-ton tailless micro excavator. Its core advantages lie in the extremely compact space adaptation of the tailless design and the side swing of the arm, the low consumption and high efficiency of Yanma power and three-party customized hydraulics, as well as the high reliability of structural components and safety configurations.

1. Ultra-flexible, the champion in narrow space operations
Tailless rotary design: The rotation radius is only 860mm. When the vehicle rotates, the tail does not exceed the width of the tracks (the chassis width is 1720mm). It can freely operate in restricted areas such as alleys, indoor spaces, and gaps between buildings, avoiding collisions with SANY Group.
Independent boom side swing: The boom can swing left and right by ±45°. Without frequently moving the entire machine, it can cover a larger working area, significantly improving the efficiency of operations near corners and walls. SANY Group.
Lightweight body: The total weight of the machine is 3780kg. The ground pressure is low (33-35kPa). It can operate stably on fragile ground such as floorboards and lawns, or on platforms with limited load-bearing capacity, suitable for scenarios such as landscaping and roof engineering.  
2.High efficiency, low consumption, durable
Yanmar 3TNV88 Euro IV engine: Rated power 20.2kW, maximum torque 104.5N·m. Powerful and reliable, with low maintenance costs, suitable for long-term continuous operation.
Three fixed-load sensitive hydraulic system: precise matching of pumps and valves, smooth and seamless compound actions (such as digging + rotation + movement), low pressure loss, 9.2% lower fuel consumption compared to competitors in the same category, saving nearly 3,000 yuan per year, and improving operational efficiency by 3.3%. Sany Group.
Efficient operation parameters: Travel speed 4.2/2.4 km/h, rotation speed 10 rpm, combined with a 30.4kN bucket digging force, efficient progress for small earthwork, crushing, and dredging operations. 
3.Robust structure, convenient maintenance, and reduced total life cycle cost
Comprehensive upgrade of structural components: Anti-wear plates are added to the back and sides of the bucket, the chassis is reinforced, the cross-section of the arm is optimized, and the anti-deformation ability has been significantly enhanced; The bucket teeth are changed from vertical pins to horizontal pins, and the replacement speed has increased by 50%, and the service life has been extended by Sany Group.
Easy maintenance design: Large coverings can be fully opened, and key components such as the engine, hydraulic pump, and filter elements can be directly accessed from the ground. Daily inspections and maintenance do not require climbing, saving maintenance time and costs by Sany Group.
Four wheels and one belt durability: 4 supporting wheels on each side + 1 idler wheel, bilateral installation improves force distribution, reduces sticking, and extends the service life of the tracks and the wheel system by Sany Group. 
4.Safety and comfort are equally emphasized, suitable for various working conditions
Safety configuration is top-notch: The bulldozer bucket and swivel cylinder are equipped with hydraulic locks as standard, reducing cylinder settlement and ensuring stable operation posture; optional remote operation can be installed, combined with front and rear high-definition cameras, enabling remote operations in high-risk areas such as mines and tunnels, eliminating the risk of personnel injury.
Comfortable driving: The cab has passed ROPS/FOPS certification, featuring a high-back cushioned seat to reduce fatigue; optional air conditioning for heating and cooling, suitable for high/low temperature environments; the hand controls have been upgraded with electronic control, ensuring precise and effortless operation.
Flexible configuration: You can choose the cab version or the cab shelter version, meeting different working scenarios and budget requirements. At the same time, additional weights can be installed to enhance the range and stability of long-arm lifting operations. 

5. Multi-functional, suitable for all scenarios of operation
Compatible with multiple tools: Standardly equipped with two auxiliary hydraulic circuits and quick connector hydraulic pre-configurations, it can quickly switch between crushers, hydraulic shears, grabs, rotary drilling rigs, etc., covering dozens of work conditions such as excavation, crushing, debris removal, greening, demolition and modification, achieving "one machine for multiple functions", and improving equipment utilization rate.
Mine / Tunnel Adaptation: Optional remote control function + dust-proof and waterproof upgrades, capable of completing operations such as ore crushing, debris removal, and stripping in underground mines, and efficient dredging and initial support repair in tunnel construction, solving the problem of personnel operations in high-risk scenarios.
