Excavadoras de segunda mano empujadas por la montaña en 2019

1. Efficient engine: The SD22 is equipped with Celect electric injection control technology, which optimizes combustion and advanced dual pulse injection chamber design to achieve efficient fuel injection and precise stable control, thereby reducing fuel consumption and complying with European emission standard IIIA. In addition, Its full power matching system ensures excellent fuel economy under high load conditions of 75% to 90%.

2. Excellent maintenance: The design of SD22 reduces maintenance points and maintenance work time, including reducing the grease filling points of K-shovel, temperature controlled fans do not require lubrication of pulleys, wet brakes do not have unadjusted brake bands, etc. These designs reduce the complexity and cost of vehicle maintenance.

3. Reliable performance parameters: The working mass of the excavator reaches 38500 kilograms, with a specific ground pressure of 92.7 kilopascals, and the excavator has high load-bearing capacity and stability. In addition, SD22 also has various walking speed options, including forward speed and backward speed, to adapt to different needs of work scenarios.

4. Adapt to various working environments: The SD22 excavator is suitable for various working environments, including coal, rock, desert, and sanitation. Especially under coal working conditions, SD22 adopts special configurations such as air pre filters and radial sealed air filters to meet the high requirements of coal mine construction for overall sealing and filtration.

5. Aesthetics and Safety: Through technological innovation and the application of new processes, SD22 outperforms similar domestic products in terms of main technical parameters, component configuration, comfort, maintainability, reliability, and operability. The safety and aesthetics of the entire machine have also been significantly improved.
