XC870K/XC870HK is a K series backhoe loader newly launched by XCMG. This product is upgraded on the basis of the mature equipment and technical performances of present products, including the upgrade of engine emission, lightweight upgrade of structural parts, and optimization of working device parameters, to further improve the comfort, safety, maintainability, reliability, supportability, and economy of the product.
The overall layout and the axle load distribution are more reasonable to achieve better traveling stability and the maximum traveling speed is up to 40km/h to realize faster site transfer speed.
The domestic leading hydraulic system distribution technology features high energy-saving and efficiency. Themaximum flow is 154L/min to meet the configuration demands of more attachments.
It can be applied with diversified environment adaptability technologies, including the high temperature, low temperature, highland, and heavily dusty environments, upon the user’s customization depending on own needs.
The highest breakout force on the loading end is leading the industry by 15%~20% compared with like models. The advanced structure and hinge points on the digging end and the industry’s largest rotating angle of the bucket ensure strong soil holding capacity.
The double pump confluence system with unloading function can automatically or manually switch over the individual pump based on the working condition and unload the high pressure by auxiliary pump, featuring high intelligence and energy-saving.
The XCMG’s independently developed load-sensing system features smoothdigging and loading combination motions, low motion changeover impact, and high efficiency and energy-saving.
During the digging and loading combination operations, the engine power to the drive system can be easily cut off so that all power is supplied to the hydraulic system to improve the digging and loading efficiency.
The machine automatically switches to two-wheel drive mode while traveling in gear IV to eliminate the parasitic power loss.
