Backhoe loader, is an engineering vehicle belong to construction machinery/construction equipment
Description of Backhoe Loader:Backhoe loader, also known as a loader backhoe, is an engineering vehicle belong to 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 WZ30-25:1. Equipped with reliable genuine Cummins engine2. 4 forward & 4 reverse synchromesh mechanical shift transmission3. Combined seal cylinder obtains high seal performance and more reliability4. Improved loader and backhoe performance5. CARRARO wet type rear axle with multi-disc brake& CARRARO front axle6. New-type cab with more space, increases comfort and visibility7. With 2 wheel driving or 4 wheel driving for optionApplications of Backhoe Loader WZ30-25: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 WZ30-25: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.
