WZ30-25 Backhoe loader
**Main Performance:
1. Backhoe loaders exclusive use chassis, compact structure, rationally distributed.
2. Equipped with totally enclosed cab with broad vision and attractive outline design, It is comfort and reasonable to control the machine with its full range and humanization design in control system.
3. Adopt the Weichai DEUTZ engine, which is green environmental protection, high power, less fuel consumption, high working efficiency, low use cost.
4. The imported professional digging/loading transmission system from Italy, and Chinese top brand hydraulic systems enable the high stability, and the machines performance could reach the international advanced level.
5. Excellent digging/loading performance brings the best return on customers investment.
6. The imported driving axle with differential lock and wet-type brake ensure the hauling ability and safety performance. Big steering angle and big oscillating angle of swing steering axle ensure the high steering ability. Driving brake and parking brake system adopt the self-regulating, full-regulating wet-type brake with free-maintenance.
7. Optional two-wheel drive or four-wheel drive could meet customers requirement.
8. Various optional tools could be equipped according to customers requirement.
**Loading Performance
Mono lever controls booms rise and fall overturn of the loading bucket and the clutchs shift.
Automatic leveling system of loading bucket avoids material drops out, automatic reposition after dumping.
In-line arrangement double cylinder of the loading system has the superior breakout force. The loading bucket could completely turnover.
Digging Performance:
Spread wing style outriggers and MID-type excavating gear, with superior working stability.
Attached with different attachment, it could accomplish different operations, such as excavating, crumbling, skiving, etc.
Excavating control valve with six jumper valves, special designed buffer system, ensure the working process smoother and steadier.
