Backhoe loader for sale: 1.Loading capacity:160m3/h 2.Total weight:22t 3.Out dimension(mm):10349 x 2450 x2724

(1) General overview

In the construction of railway and highway, excavation of large-sized tunnel plays a key role in deciding construction progress, so the quality of a backhoe loader influences the construction progress.

Backhoe loader made in ZZHZ features:

High efficiency, energy savings and low noiseDouble power hydraulic system, choosing to use in different occasions; disel power hydraulic system should be chosen as the machine moves in the tunnel or works outside; while the electric hydraulic device featuring high efficiency, safe and environmental protection should be chosen as the backhoe loader works in the tunnel with narrow space and bad air quality.

Entire hydraulic drive: hydraulic motor drives the loader to move and carry the ballast, its working institution is driven by hydraulic cylinder. The control panel controls power and hydraulic system of the complete machine. Hydraulic system adopts pilot control, featuring reasonable layout and convenient maintenance.

3. Safety device is installed in the electrical system and hydraulic system to ensure safe and smooth work of the machine

4. Better generality, can be used in tunnel construction and tunnel muck hauling as well as loading scattered items outdoor. The backhoe loader is used in large scale tunnel, national defense and hydroelectricity construction projects such as colliery, mine, road and railway.

5. The backhoe loader continuously excavate, scrabble and convey ballast to shuttle type mine car and other vehicles, featuring smooth loading, large-scope excavating, not sprinkled material, high efficiency and strong continuity.

Max applicable gradient: 11°

(3). Applicable condition

1. The backhoe loader has a wide work range moving by crawler. In the tunnel construction, WZ160 backhoe loader is suitable for tunnel section above 3.5m

2. Work face demands better drainage condition, lower water level than work face level. No strict demand on walking road, working environment temperature: -5~40°C (please negotiate with the manufacturer when the environmental temperature is above that)

3. The backhoe loader usually loads rock ballast with loose density ≤1.8t/m3, hardness < 12, when the ballast hardness rises, it will speed up to ware the spear parts and reduce service life of the complete machine. WZ160 backhoe loader load the ballast with a thickness < 600mm

4. The backhoe loader is suitable for construction in mine roadway, suitable for construction projects such as railway tunnel, road tunnel and water & electricity division tunnel without explosive mixture such as gas and coal dust.

The backhoe loader uses double power producers: motor with 50HZ 380V (660V)A.C power supply, internal combustion engine with self fuel tank. They are used in different conditions according to working conditions. All electrical systems choose qualified electrical elements, high efficiency assembly of internal combustion engine.

Attention

 WZ160 backhoe loader can not work in construction projects such as railway tunnel, road tunnel and water & electricity division tunnel with explosive mixture such as gas and coal dust
