New and Cheap Backhoe (Xt870)
XT870 is a kind of the multi-functional engineering machinery incorporating and loading into an organic whole. It adopts the advanced static hydraulic transmission and popular integral structure overseas with the following advantages: The complete machine is rationally distributed and compact; It is comfortable and convenient to handle, the turning radius is small and the cost performance is high. It is widely used in municipal administration, the construction of projects such as the building, the oil field, water conservancy, the forest farm, the military project, and so on. It also can be used in excavating, carrying and leveling and can carry on the flexible and swift homework to scarp heap and waste residue of the large and medium-sized enterprise.

It has the high power and good performance ability. The key parts such as the engine, the case, the bridge, the hydraulic system, etc. Adopt the import components, which have improved the dependability of the complete machine. Components, which have improved he dependability of the complete machine.
The stability of performance and traveling has been improved by means of the highest speed, the small turning radius and the adaptation of integral frame. In addition, single pump supports oil and the hydraulic steering system make the systematic pressure reach 21Mpa, which has improved the performance ability of the complete machine. The highest speed reaches 40.2km/h. Which has improved the production efficiency of the complete machine.
It is easy and simple to handle. You can change the shelf in moving. The loader is operated by single pole and the digger by a pair of poles. The complete machine puts excavating as the focal point of performance, so it has obviously improved the excavating stability in structural design.
The whole day-lighting closed drives cabin is furnished with the system of the air conditioner, ROPS system. It is safe and comfortable, and the visual field is broad. It adopts the sound insulation, uses the whole day-lighting drivers cabin which puts the system of fluorine-free air conditioner, which improved the comfortableness of the operating environment, guarantee the clear visibility. It adopts the wholly-tumbling.
