SANY SY140C-9i Small Excavator
Product Feature
Self-developed load sensing system of SY140C-9i small excavator (14 ton excavator) achieves a constant overall power by varying the force of each pump, ensuring micromanagement and operating accuracy.
Advanced Dynamic Control
The Dynamic Optimization Matching Control System (DOMCS) intelligently matches the engine system and hydraulic drive system, improving working efficiency by 6% and reducing fuel consumption by 10%.
The variable operating modes of SY140C-9i 14 ton excavator include heavy-duty mode, standard mode, light-duty mode and break mode, allowing the machine to be ready for versatile operations in any environment.
The advanced GPRS can monitor the accurate location of the machine and the machine's dynamic in real time.
The remote error diagnosis gives the feedback in real-time, helping solve problems without delay.
The smart machine alerts provide danger warning, ensuring the safety of the operator and the machine.
High Stability and Reliability
Robot-welding Process
Robot-welding process ensures a strong and durable structure.
Reinforced Boom
The ear plates have been redesigned to reduce stress at the joint. The boom passes certified tests including working for long hours and digging in harsh environment.
Reinforced Bucket
The bucket has been redesigned to make it suitable for multiple working conditions. Durability is enhanced with the anti-wear and thickened plates on the bucket bottom, so that no damage is caused to the bucket during field digging (soil and rock mixture).
Swing Platform
Reinforced plates that are welded on the two main beams of the swing platform considerably increase resistance to bending. Made of top-grade steel and formed through punching, the beams are designed with a D-shaped structure and greatly strengthen the platform.
User Friendly Design
Innovative, Large Cab
Large windows on three sides provide a wide view. The ergonomically designed joysticks and chair provide a comfort experience for the operator.
High-quality Air-conditioner
The air conditioner with multiple air outlets at different levels and locations provides better cooling effect. And the air outlets can be adjusted as desired.
Silicone Rubber Shock Absorber
The operator station is equipped with an innovative silicone rubber shock absorber. This shock absorber is fixed to the swing platform in four points that minimizes the shock, considerably increasing cab stability and improving operator comfort.
