China 70 Ton Large Excavator Digger with Bucket 3.5cbm

This machine has adopted an energy-efficient engine with the emissions in accordance with the Tier 3 standard and the engine fuel and intake systems use the three-stage and four-stage filtration respectively.
Its key hydraulic components are all imported and its hydraulic system is a mature and reliable negative flow control system; an independently researched and developed electric control system is applied to realize perfect matching of the engine and the main pump and simultaneously reduce the complete fuel consumption.
Its GPS remote monitoring system equipped can achieve real-time control of the complete running state and fault information. The reinforced chassis adopts a modular design, able to improve the working stability. Its slewing platform adopts a large-sized H-beam structure, able to effectively improve the capacity of the excavator to withstand the positive and negative bending moments. The key stress parts of the swing arm bucket rod adopt a casting structure with a large-capacity rock-oriented bucket used to improve the bucket strength and productivity.
A reinforced cab in accordance with the FOPS certification as well as an embedded 7-inch LCD screen is used to offer drivers safe and high-quality driving enjoyment. The complete machine features low vibration, low noise and comfortable operation by virtue of the in-depth research on the vibration of the complete XE700C and the optimization design of the structural members. In general, XE700C boasts high-end configurations, high efficiency, low fuel consumption, low noise and high reliability, able to serve mine construction as ideal operation equipment.
