he main structural features and advanced technology used in the SAM388 Backhoe loader
一、主要特点：main feature
1.采用高可靠性的液力变矩器和变速箱提供超强动力，加重工程专用桥行走平稳、可靠性高。The use of high-reliability hydraulic torque converter and Gearbox to provide super power, aggravated the smooth and high reliability of the dedicated bridge walking
2.将挖掘机和装载机两机合为一体，一机多能。完全具备小型挖掘机和装载机的所有功能，更适合在狭窄空间作业，方便灵活，工作效率提高30%以上。Combine the excavator and the loader into one, and one machine can do more. Fully equipped with all the functions of small excavators and loaders, it is more suitable for operating in a narrow space, convenient and flexible, and working efficiency is increased by more than 30 %.
3.挖掘、装载功能全部先导控制，轻便灵活，作业效率高。Mining, loading function all lead control, light and flexible, high operating efficiency.
4.人性化设计旋转减振座椅，全钢化成型玻璃驾驶室，视野更宽阔，驾驶更舒适。Humanized design of rotating vibration absorber seat, fully steel-molded glass cab, wider vision, more comfortable driving.
5.挖掘可侧向滑移机构装置，使挖掘作业范围更大，效率更高。Excavate the lateral sliding mechanism device to make the excavation operation more extensive and more efficient.
6.前翻式护罩的设计，大大提高了整机的维护性。The design of the front flip cover greatly improves the maintenance of the entire machine.
7.可选配多种附具装置，完成多种施工作业。用于市政、建筑、水利、公路、自来水、供电、园林等部门，可从事农业建筑，管道铺设，电缆敷设，园林绿化等作业。A variety of accessories can be selected to complete a variety of construction operations. For use in municipal administration, construction, water Conservancy, highways, tap water, power supply, gardens and other departments, can be engaged in agricultural construction, pipeline laying, cable laying, landscaping and other operations
