Backhoe Loader

Features of Backhoe Loader

1. A central hinged frame, featured by small turning radius, flexible trafficability and excellent lateral stability, is convenient for operations in narrows sites.
2. The design of loading attachment exterior refers to the 3CX structure of JCB Corporation inUK, while the exterior of excavating gear refers to the 310SE structure of John Diehl. By using this advanced technology, the overall appearance of the backhoe loader seems more attractive. And the cab, with large turning glass in front and rear, has good lighting and wide visual field.
3. The brake system of the backhoe loader is safe and reliable by adopting air-over-oil caliper disc type foot brake system and drum-type hand brake.
4. The hydraulic mechanical drive system enhances the reliability of the drive system.
5. The backhoe loader adopts full-hydraulic steering, power-shift and hydraulic control to a working device, which ensures the light and flexible operation and stable and reliable movement.
6. Low-voltage wide-base engineering tyres and rear axle with manual swing are adopted to reach excellent cross-country ability and trafficability.
7. The digging device with the property of lateral sliding enables a wider application range of the backhoe loader.
8. The machine uses suspending damping chair with handrail and seat belt, which improve the security and comfort.
9. It is easy to observe the oil level for the convenient position of the fuel tank.
10. TOPMAC is an ISO 9001 accredited backhoe loader supplier inChina.
