Sany Crawler Excavator Deformation Resistance Sturdy Durable Hydraulic System
- Fuselage constructed with high-strength steel and multiple strengthening processes for excellent wear and deformation resistance
- Maintains structural stability even in complex conditions (mine gravel, construction muck operations)
- Reduces maintenance frequency despite normal appearance wear (paint wear, rust)
- Demonstrates industrial-grade sturdiness and durability in core components
- Equipped with high-torque engine and optimized hydraulic system
- Strong digging force with quick boom and stick response
- Efficient performance in various operations: hard soil excavation, material handling, fine site leveling
- Helps shorten project construction timelines
- Site excavation (foundation pits, trench excavation)
- Earth and stone transport
- Construction waste cleaning
- Ideal for limited space and diverse tasks in urban construction sites
- High-intensity operations (ore mining, site leveling)
- Effective ore crushing and loading
- Important role in open-pit mine scenarios
- Improves mining operation efficiency
- Urban river dredging
- Road reconstruction and expansion
- Municipal facilities construction (underground pipe galleries)
- Adapts to various operating environments
Note: Due to individual equipment differences, actual specifications should be verified against equipment nameplate.

- Air in hydraulic system pipeline
- Component wear (bearings, gears)
- Loose track links
Check hydraulic system and perform exhaust operations (start equipment and slowly operate each action to exhaust air). For mechanical component wear, professional inspection and replacement required. Adjust track tension if links are loose.
- Hydraulic oil contamination affecting pressure transmission
- Main pump wear
- Abnormal pressure setting of relief valve
Replace with qualified hydraulic oil and clean system. Inspect main pump - repair or replace if necessary. Have professional technician detect and adjust relief valve pressure parameters.
- Inconsistent track tension
- Uneven flow of travel motor
- Wear/deformation of guide wheel/roller
Adjust track tension to be consistent on both sides. Check travel motor and troubleshoot flow problems. Replace worn guide wheel and roller components as needed.
