371HP SINOTRUCK HOWO 70 tons mining dump truck, popular using in mining sites
Applications:
It is suitable for in normal roads and tough roads, to transport and unload transport, stone, ore, and others loose materials.
Competitive Advantage
1. The main reducer is reasonably designed. The support stiffness is good. The combination of forced lubrication and splash lubrication makes the service life of the reducer improve greatly.
2. The reinforced type cast axle housing is reasonably structured. Its wall thickness transits uniformly and its bearing capacity is two times that of common STEYR double axle.
3. The reinforced type drum brake with the Φ500×235 ultra-wide brake shoe is adopted. It has reliable braking performance and long service life.
4. Adopting cross-mounted arrangement, the driving bevel gear's strength and stiffness are improved substantially.
