1. Great intensity： Heavy-duty rack, thicken steel tubes with high intensity,large section are adopted. One-piece frame with high manufacturability, high rigidity and great intensity.

2. Deep working depth: 65MN discs (760mm diameter, 8mm thickness) are strictly treated by heating process which ensures wear-proof and strong tenacity.

3. Small resistance：Built-in anti-friction bearing；mechanical seal；small tractive resistance；easy to operate, repair and maintain.

4. Stable：forged axle with large diameters and big nut., which ensures intensity.

5. Easy to transfer: hydraulic folded plastic tires. Wide tire improves efficiency and service time. 

6. Heavy-duty: total weight exceeds 2400kg, ensuring deep working depth.
