The tailless design is the most distinctive feature of the SANY SY26U. The tail's turning radius is approximately 775mm, allowing for a 360° rotation within the width of the tracks. This ensures that there is no need to worry about damaging the counterweight or surrounding objects when operating in extremely narrow spaces such as at the base of walls, corners, or indoors. Combined with the adjustable working device (with a certain range of left and right deflection angles), it can directly reach the outer edge of the tracks, eliminating the need to frequently move the machine body in confined conditions such as beside walls or in ditches. This significantly improves the operational efficiency. It can pass through narrow passages, elevators, and indoor doorways, making it particularly suitable for scenarios with limited space such as house renovations, basement construction, and landscaping. 

1.Fuel Economy
Equipped with Kubota D1105 or Yanmar 3TNV80F engines (rated power 15.4kW/14.6kW), it adopts a load-sensitive hydraulic system. It can automatically adjust the flow distribution according to the load, and is compatible with continuous throttle speed control. In light-load conditions, it can reduce the rotational speed and save fuel consumption. Compared with some models in the same category, the overall fuel consumption is relatively lower, and the operating cost is well controlled. 

2. Multi-functionality
Standardly equipped with auxiliary hydraulic pipelines (some configurations are dual pipelines), it can quickly switch between various auxiliary machinery such as hydraulic hammers, hydraulic shears, augers, timber grabbers, and pillow clamps, achieving multi-purpose operation with one machine. In different working conditions such as municipal pipelines, landscaping, farmland renovation, and railway maintenance, by replacing the attachments, it can adapt to different operation requirements, resulting in a relatively high return on investment. The hydraulic system has good coordination of compound actions and high precision of micro-operation, and performs stably in fine operation scenarios (such as indoor demolition and trench excavation). 

3. Operational Comfort
The cab adopts a quick disassembly design (with 8 sets of fasteners), enabling it to adapt to low-lying working environments (such as greenhouses and basements). Standard features include shock-absorbing seats, multi-functional handles (integrating crushing functions), and intelligent displays. The points for daily maintenance are centrally arranged. Most of the air filters, oil filters, and fuel filters can be inspected from a standing position on the ground, making maintenance convenient. Compared to imported mini-excavators in the same category, the purchase cost is relatively reasonable. The Sanli after-sales service network is extensive, and the supply of spare parts is relatively sufficient.

4. Structural Reliability
The key structural components (boom, bucket arm, chassis) are made of high-strength steel, and the front end of the bucket arm is reinforced with wear-resistant plates. The structure of the crawler support wheel frame has been optimized, featuring a design of 4 supporting wheels on each side, with a reasonable wheel spacing distribution, resulting in relatively good overall stability. Under normal small-scale engineering operation conditions, the durability performance is stable. Some configurations adopt self-lubricating slewing motors, and the maintenance-free design further reduces the long-term usage cost.
