Description of Backhoe Loader

Backhoe loader, also called a loader backhoe or backhoe, is an engineering vehicle belonging to construction machinery or construction equipment. Generally, the backhoe loader composes a tractor, fitted with a shovel/bucket on the front and a small backhoe on the back.

Features of Backhoe Loader

1. Equipped with reliable WD Duetz engine;
2. 4 forward & 4 reverse synchromesh mechanical shift transmission;
3. Combined seal cylinder;
4. CARRARO wet type rear axle with multi-disc brake& CARRARO front axle;
5. Spacious cab for more comfort and visibility;
6. With 2 wheel driving or 4 wheel driving for option;

Applications of Backhoe Loader

Backhoe loader is commonly used in urban engineering and small construction projects (such as building a small house, fixing city roads etc.).
