The characteristics of construction rubber track undercarriage
1. High cost.
2. Heavy weight,big load capacity.
3. Drive device,big load capacity equipment generally is composed of hydraulic motor,gear-box,brake, valve bank .small volume,heavy weight,big driving force,and two rubber tracks can turn at the same time, and the turning radius is small.
4. Rubber track is special for construction machinery,there are many kinds models in market,different load capacity use different pitch.Construction rubber track is thicker than agricultural rubber track,Wear-resisting, good tensile strength, can walk in complex conditions.
5. Wheel roller in good-seal, free maintenance in life, high machining accuracy, good cooperation, durable use.
6. Tension device is composed of oil cylinder,spring and other parts.By injecting butter into the cylinder, the shaft can reach the purpose of tightening, which has a cushioning effect. It has a small impact on the parts, and it is not easy to remove.
7. Truck frame is strong,heavy weight,big load capacity,good impact resistance.
