Description:
SD7HW bulldozer is power shift drive, semi-rigid suspended and hydraulic controls.
Applications:
It is an ideal machine used in communication, desert, oil field, power, mining etc large earth moving program.
Competitive advantage:
1.Braking system utilizes hydraulic bossting structure, which is convenient and labor-saving.
2.The final drive gear has the characteristics of large displacement coefficient value.
3.This kind of design raises bearing capacity and prolongs the useful time.
4.The equalizer bar utilizes free lubricating structure to decrease service cost.
