New upgrade - superior performance

1. Powertrain:

• SY18U adopts SANY custom Yanmar 3 TNV80F engine, power 14.6kW, meet the national four emission standards, powerful, reliable and durable, to meet the diversified power needs of customers.

• Using a high-precision oil-water separator with a filter, the water can be separated while effectively filtering impurities in the fuel, providing multiple protection for the engine and extending the service life of the engine.

2. Hydraulic system:

• The hydraulic system uses a large torque main pump and a large flow main valve to ensure the efficiency of excavation and crushing operations.

• Load-sensitive traffic allocation system: It can provide and allocate traffic according to the system's needs for traffic to meet regulations

• Line component speeding and composite motion requirements. By optimizing the hydraulic system to achieve a precise match with the engine, achieving precise movement and smooth handling.

Optimization of structural components - durability

1. Structural component upgrades

• Based on the finite element analysis, optimize the frame and work device, prolong the service life.

2. Standard hydraulic lock

• Increase the deflation hydraulic lock and the bulldozer hydraulic lock to enhance the maintenance function of the bulldozers and work unit.

3. Improved excavatoring and walking power

• The standard high-torque walking motor improves walking capacity by 13%.

3. Upgrade the cockpit and arm fuel tank

• The cockpit is mounted horizontally, making it easy to disassemble.

• The length is increased and the service life is extended.

• The bulk of the arms cylinder increases the lift.

Upgrade the driver's room - a new experience

1. Seat upgrade:

• High-end levitating seats, djustable wristrests, comfortable operation

2. Optimize key switches and power interfaces:

• The newly developed high floor pad, the floor pad to the seat installation surface of the distance compared to the three countries reduced by 20mm, improve operating comfort. The floor mat is simple in pattern and at the same time is slippery resistant, making it easy to clean.

Trinity Digging - A Multi-Faced Expert

1. Multiple uses of a single machine

• SANY Micro Excavator is equipped with standard auxiliary pipeline and cut-off valve, which can be directly installed with breaking hammer and other auxiliary tools. Legendary Weapons of China are proficient in everything.

• Sany Min digging originally had narrow trenches, wide trenches, weed rakes and other tools, with different working conditions and different tools, and higher efficiency.

2. Applicable scenarios:

• Standard auxiliary pipes and cut-off valves can be directly installed as auxiliary tools such as crushing hammers, and originally adapted narrow bore, wide bore, and weed brushes, with different tools and greater efficiency. Housing renovation, landscaping, vegetable sheds, trench excavation and soil improvement can be done

3. A deflable device

• The deflection working device range is: 625mm left, 400mm right, both sides can easily dig to the outer edge of the track,

• You can operate in space-limited locations such as wall corners.

4. Stretchable walking rack

• The width adjustment range of the retractable walking frame is 980mm ~ 1350mm, which improves the stability of the whole machine.

• The interchange of steel tracks and rubber tracks can be achieved to meet the needs of various work conditions.

5. Rotatable earth shovel

• The rotary inserted bulldozer can ensure passability, so that the excavator can easily pass through the working space of less than 1 m, and improve the working efficiency.
