Description

388H backhoe loader

The main structural features and advanced technology used in the

XINFA  388H(4TX)  backhoe loader

1.Adopt self-developed torque converter and gearbox with high reliability to provide super power for the excavator loader, and increase the smooth walking and high reliability of the special bridge for the project; It can realize crab walking, front-wheel steering and four-wheel steering, which can adapt to different working conditions. The use of 16.9-28 tires, the ground clearance is large, the off-road passing is stronger; High reliability and higher hydraulic torque converter and gearbox, for the excavator loader to provide super power, increase the engineering bridge running smoothly, high reliability; It can realize crab walking, front-wheel steering and four-wheel steering, which can adapt to different working conditions. The use of 16.9-28 tires, the ground clearance is large, the off-road passing is stronger;

2.The excavator and loader are integrated into one, one machine can do more. Fully equipped with all the functions of excavators and loaders, it is more suitable for working in narrow Spaces, convenient and flexible, and the work efficiency is increased by more than 30%.

3.Excavating and loading functions are all pilot controlled, light and flexible, and high working efficiency.

4.Humanized design rotating vibration damping seat, all tempered glass (FOPS&ROPS) high-end cab, wider vision, more comfortable driving.

5.The full hydraulic lateral slip mechanism is adopted in the excavation, which saves time and labor, and makes the digging operation scope larger and the efficiency higher.

6.The design of the front flap shield greatly improves the maintainability of the whole machine.

7.A variety of accessories can be selected to complete a variety of construction operations. Used in municipal, construction, water conservancy, highway, water supply, power supply, garden and other departments, can be engaged in agricultural construction, pipeline laying, cable laying, landscaping and other operations.
