Key Features & Advantages

1. Powertrain & High Fuel Efficiency

Equipped with a high-torque, low-consumption Isuzu/Yanmar industrial diesel engine, with strong power output and reliable performance in high-altitude, high-temperature and cold environment.
Matches SANY’s self-developed positive flow hydraulic control system, which reduces fuel consumption by 10%-12% compared with traditional negative flow systems, with comprehensive operation fuel consumption only 6-8 L/h.
Built-in auto-idle and automatic engine stop functions cut unnecessary fuel waste during no-load standby.

2. High-precision Hydraulic System

Core hydraulic components (main pump, main valve, travel motor) adopt international top brands such as Kawasaki, with 15% faster action response than peers.
Optimized compound action logic ensures smooth coordination of boom, arm, swing and travel actions, suitable for both heavy earthmoving and fine operations such as pipeline laying and landscaping.
Equipped with boom anti-drop valve and arm holding valve to avoid sudden falling of working devices, greatly improving operation safety.

3. Super Structural Durability

The X-type undercarriage, boom and arm are made of high-strength Q355 structural steel, optimized by finite element analysis, with reinforced plates added at stress concentration positions, passing 10,000 hours of extreme load test.
Sealed and lubricated track chain, floating sealed carrier rollers and idlers prevent silt intrusion, extending service life of chassis parts by 30%.
The bucket is made of wear-resistant NM400 steel, with reinforced side plates and high-wear-resistant bucket teeth, suitable for harsh working conditions such as rock excavation.

4. Operator Comfort

ROPS/FOPS certified cab provides anti-rollover and falling object protection, with large curved glass for 270° ultra-wide field of view.
Fully adjustable air suspension seat, low-effort pilot control handle, and full-automatic constant temperature air conditioning reduce long-time operation fatigue.
High sound insulation design reduces interior noise to only 72 dB(A); the 8-inch intelligent monitor displays real-time equipment status, fault alarms, and supports Bluetooth connection and USB charging.

5. Easy Maintenance

All maintenance points (oil filter, fuel filter, air filter, hydraulic oil check port) are arranged at ground-accessible positions, no need to climb the vehicle for daily inspection.
Extended service intervals: engine oil changed every 1000 hours, hydraulic oil changed every 5000 hours, greatly reducing downtime and maintenance cost.
Built-in SANY SYNC remote management system supports real-time monitoring of equipment location, working hours, fuel consumption and fault early warning, which is convenient for fleet management.

Typical Applications

Municipal construction: road repair, pipeline laying, urban site clearing
Landscaping: tree planting, trench digging, site leveling
Earthmoving: small construction site foundation excavation, earth transfer
Small mining and quarrying: material loading, rock excavation (with breaker)
Agricultural construction: farmland renovation, water conservancy trench excavation
Narrow site operation: the short-tail SY155U is suitable for urban old city reconstruction, indoor demolition and other restricted space scenarios.

Optional Attachments & Configurations

Working tools: earthmoving bucket, rock bucket, hydraulic breaker, log grapple, hydraulic shear, auger drill
Auxiliary configurations: quick coupler (for fast tool change), dozer blade, rear view camera, heated seat
Customized packages: cold area package (engine oil heater, battery heater), high temperature package (enhanced cooling system)

After-sales Support

SANY provides global 24/7 after-sales service, with spare parts warehouses in more than 150 countries and regions, and promises to arrive at the site for maintenance within 48 hours in most regions, providing 1 year or 2000 hours of standard warranty.
