Front Steering Axle of 12 Ton Wheeled Excavator
1.The main gearbox with quasi-hyperbolic spiral gear provides high efficiency, stable operation, and low noise level.
2.The planetary gearbox type NGW has a rational and compact design.
3.The hydraulic drum brake guarantees reliability and safety in braking.
4.The hydraulic steering system provides smooth control.
5.The steel cast axle body has high load-bearing capacity and rigidity.
6.The oil seals of the bearings and key components are made from imported components from well-known brands, which ensures a long service life.
7. Suitable for wheeled excavators with a load capacity of 8–12 tons.
MAIN CHARACTERISTICS:
The rear axle of the 12-ton wheeled excavator is matched with the 8-12 ton wheeled excavator. The axle housing is made of cast steel, while the główn gear unit adopts a hypoid spiral bevel gear that meets the requirements of a precision drive system. The wheel nut implements a planetary reducing mécanism of the NGW type. For braking systems, hydraulically actuated normally open standard wheel brakes are used, which provide reliable braking performance and lightning-fast design.
