Structural parts are more durable
- Install large and small arms with heavy loads with better durability, use cast steel to improve strength and improve durability by 1.5 times;
- The walking and rotating motors are designed by Hyundai Heavy Industries to enhance durability;
- Increased lower support ring thickness and 20% lower frame welding strength;
