Mining Dozer
Scroll down
The STONE development team has developed a series of high-quality OEM chassis components specifically for mining machines, such as Caterpillar, Komatsu, Hitachi, Liebherr and other mainstream brands. including but not limited to track groups, track rollers, carrier rollers, the drive sprocket, and idlers with supports.
Undercarriage spare parts for mining excavators.
The bulldozer undercarriage's service life has been significantly extended by enhancing pin and bushing retention.
Developed to original factory specifications, we effectively reduce axial play and precisely control seal movement.
This engineering approach significantly improves pin/bushing wear resistance.
+ Up to 25% longer service life compared to general purpose (GD) + 15–30% lower operating costs compared to General Purpose (GD)
+ Industry-leading performance
+ Pin and bushing coatings extend seal life
