track group,we can offer stable quality and competitive prices

1. Have wide choice range,the chain and oil chain are applicable to special model of crawler type excavators and bulldozer from 0.8T to 100T. It’s widely applied in bulldozers and excavator pf Caterpillar, Komatsu,Hitachi,Kobelco and hyundai etc;

2. Made of special steel material,pin and bush go through special heat treatment,so the wear-resistance is improved to maximum extent;

3. Chain inside is spread with lubrication oil and equipped with polyurethane dust seal and further prolong life time;

4. All chains are assembled with the high precision design and manufacturing parts.

   High-degree inductive harden surface;

5. The chain through thermal refining first, and then its chain rail surface undertakes medium frequency induction.All the heat treatment ensure chain strength and wear-resisting property greatly;

6. The bushing is done the carbonization, ensure the reasonable hardness of core and abrasion resistance of internal and external surfaces;

7. The pin is done the tempering and the surface medium-frequency quenching treatment,which ensures the sufficicnt hardness of core and abrasion resistance of external surfaces.
