XCMG Heavy Excavator 40t Hydraulic Digger 2cbm Bucket 222kW Engine For Construction Mining XE400DK.
Adopting XCMG's proprietary matching technology, the operation efficiency is higher, the fuel consumption is smaller, and the oil efficiency ratio is ahead of the same tonnage model at home and abroad. After continuous optimization and improvement of the hydraulic system, the maneuverability is further enhanced, the control is more precise, and the leveling and loading performance is better.
1. More energy-saving and environmental friendly
* By adopting Cummins imported electronic fuel injection engine, the machine has stronger power and higher fuel economy.
* High pressure common rail system realizes optimum fuel injection control and effectively improves combustion efficiency.
* With optimized engine power curves and low-speed and large-torque output, the fuel consumption is greatly reduced while providing strong power, which satisfies dynamic balance and economy of power output and fuel consumption in heavy-duty mode.
2. More efficient return
* Efficient positive flow control system has features of high reliability, less pressure loss, high flow distribution efficiency and smooth compound movements, and energy conservation, efficiency, controllability and other aspects are greatly improved.
* Brand new positive flow sub-pump can independently control main pump, which optimizes speed sensing and load self-adaptive control, realizes on-demand, effectively reduces neutral position return loss, and achieves faster respond speed.
3. More reliable and durable * Lengthened and widened heavy-duty undercarriage, combined with reinforced exclusive working equipment for mines, bring better stability and higher reliability, which can satisfy heavy-load construction in various working modes.
* Exclusive double grouser track shoe for mines with enlarged plate thickness and track tooth height has better abrasive resistance and long service life.
