Backhoe Loader WZC20
Description of Backhoe Loader:
The backhoe loader is a kind of construction machinery/construction equipment which consist of a tractor with a bucket in front and a backhoe on the back . Backhoe loaders are very common and can be used for a wide variety of tasks: construction, light transportation of building materials, powering building equipment, digging holes/excavating, landscaping, breaking asphalt, and paving roads.
Features of Backhoe Loader WZC20:
1. Equipped with reliable genuine Cummins engine
2. 4 forward & 4 reverse synchromesh mechanical shift transmission
3. Fullclosed ROP/FOPS Cab with more space, increases comfort and visibility
5. 4 wheel driving and CARRARO wet-type rear axle with multi-disc brake & CARRARO front axle
5. Multi-purpose 4 in. 1 bucket has extended application range including loading, scraping, shoving, blade, clamping, paving and lifting.
6. The bucket is controlled through electrical- hydraulic mode.
7. Adopted Pilot valve controlling loader and backhoe valve, easy and flexible operation.
8. Extendible dipper upgrades productivity by reducing the number of travel movements.
9. The mechanical quick coupler attachment is available.
Applications of Backhoe Loader WZC20:
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.
