China New 7.5t 8t Crawler Excavator HX80
HX excavator is a newly launched HX series excavator, with high engine fuel efficiency, more environmental protection, stronger power, faster speed, with high-strength structural parts, reliable and durable working device, wide vision and spacious cab.
1. More environmentally friendly, more powerful, faster and lower fuel consumption
- New Tier 3 engine with lower fuel costs
- Diesel fuel burns fully and thoroughly, greatly improving performance
- Multiple fuel filtration systems ensure long-lasting engine use, while reducing harmful gas emissions and making them more environmentally friendly
- Optimize the oil circuit design of the main control valve, improve the working speed and composite operation capacity
- Left operating handle is equipped with a one-button idle switch, the engine speed automatically decreases, reducing fuel consumption
2. Advanced hydraulic system
- Load-sensitive system, single action operation is faster and more fuel efficient
- Parking brake for smoother and easier control during swing
- Hydraulic oil, filter element longer service life
3. The durability of structural components is longer
- Mounted with large and small arms for better durability
- Even in harsh working environments, the upper and lower frames can withstand strong impacts and stress during operation - X-shaped center frame, reinforced frame strength optimization, longer service life
4. Durable bushing
- VHD sleeve is used in the key part to increase the lubrication cycle of the pin joint
- Minimized loosening of the work unit
5. Engine damping pad installation
Optimization of the cooling module structure
- Installed engine damping pads to reduce cab seat vibration (seat benchmark approximately 30%) Compared with VS series, the heat aging durability of shock absorbing pads is improved by 40%
- The cooling module is arranged in "parallel", which greatly improves the cooling efficiency, makes the heat sink cleaning and maintenance more convenient, and improves durability
