Advanced Technology for Maximum Efficiency

1. DPC (Direct Power Control) Technology

The intelligent DPC system dynamically adjusts hydraulic power output based on real-time load conditions, ensuring that the engine operates within the most economical rpm range at all times. This results in optimized power matching – "what you need, when you need it" – reducing energy waste while maintaining peak performance.

2. Short Arm & Large Bucket Configuration

Equipped with a 2.9-meter short arm featuring a secondary pressure boost function, the SY335BH-S delivers over 8% increase in digging force compared to standard configurations. This design is specifically optimized for intensive earthmoving and aggregate loading applications.

3. Optimized Bucket Design

The standard earthmoving bucket features an optimized profile that enhances material penetration fluidity and reduces friction. The increased angle between the front cutting edge and the base plate improves bucket fill rate, while reduced average digging resistance translates directly to higher digging efficiency.

  • Standard: Earthmoving bucket

  • Optional: Rock bucket for demanding applications

4. Intelligent Maintenance System

The SY335BH-S is engineered for simplified, intelligent maintenance:

  • Air filter blockage alarm (standard) – alerts operators when filter service is needed

  • Diesel pressure sensor (standard) – enables condition-based maintenance scheduling

  • Oil-water separator with water level alarm – alerts when diesel water content exceeds safe levels

  • Large-area service doors – provide excellent accessibility for routine maintenance

  • Side-removable radiator dust screen – simplifies cleaning without extensive disassembly

FAQ

Q: What is DPC technology and how does it save fuel?
A: DPC (Direct Power Control) is an intelligent hydraulic management system that adjusts pump output based on real-time load conditions. By keeping the engine operating in its most fuel-efficient range across all working modes, it reduces energy waste while maintaining full productivity.

Q: What is the advantage of the short arm configuration?
A: The 2.9m short arm increases the leverage ratio of the hydraulic system, delivering over 8% more digging force compared to standard arm configurations. This makes it ideal for intensive digging and loading applications where maximum breakout force is required.

Q: What bucket options are available?
A: The machine comes standard with an earthmoving bucket (2.0 m³). A heavy-duty rock bucket is available as an optional upgrade for handling harder materials and more abrasive conditions.

Q: How does the intelligent maintenance system work?
A: The machine is equipped with sensor-based alarms that alert the operator when maintenance is needed – including air filter blockage detection, diesel pressure monitoring, and water level detection in the fuel system. This enables condition-based maintenance rather than time-based scheduling.
