What's the difference between starting resistance and rolling resistance?
When a cart is at rest and you want to get it moving, you are working against its starting resistance. When a cart is in motion and you want to keep it going, you are working against its rolling resistance. It's usually better for starting resistance and rolling resistance to be low because that means it take less effort to move the wheeled equipment around. In general, wheels that are larger and harder have lower starting and rolling resistance.Zhongshan Zhiqingsong Automatic Machinery Co., Ltd is an efficientand technology enterprise.
