The main structural features and advanced technology used in the SJ388 Backhoe loader
Main Feature
1.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.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.Mining, loading function all lead control, light and flexible, high operating efficiency.
4.Humanized design of rotating vibration absorber seat, fully steel-molded glass cab, wider vision, more comfortable driving.
5.Excavate the lateral sliding mechanism device to make the excavation operation more extensive and more efficient.
6.The design of the front flip cover greatly improves the maintenance of the entire machine.
7.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
