Backhoe Loader WZ30-25C
Description of Backhoe Loader:
Backhoe loader, commonly shortened to backhoe, is a type of construction machinery/construction equipment. The backhoe loader commonly composes a tractor, fitted with a shovel/bucket on the front and a small backhoe on the back.
Features of Backhoe Loader WZ30-25C:
1. Equipped with WD DETUZ engine
2. 4 forward & 4 reverse synchromesh mechanical shift transmission
3. Combined seal cylinder obtains high seal performance and more reliability
4. Improved loader and backhoe performance
5. CARRARO wet type rear axle with multi-disc brake& CARRARO front axle
6. New-type cab with more space, increases comfort and visibility
7. With 2 wheel driving or 4 wheel driving for option
Applications of Backhoe Loader WZ30-25C:
The backhoe loaders’ versatility and compact size makes them one of the most popular construction machinery/construction equipment. These backhoe loaders are widely used for larger projects such as building a house, fixing city roads, mining, etc.
Working principle of Backhoe Loader WZ30-25C:
Because the design of backhoe loaders is top-heavy and the swinging weight of the backhoe could cause the vehicle to tip, backhoe loaders use hydraulic outriggers when digging and lower the loader bucket for additional stability.
