Heavy objects, such as bagged cement or sand, are filled into the weight bins to complete the adjustment of the center of gravity. When the trailer is towing the towing mechanism, the trailer will not roll over due to the shift of the center of gravity of the towing mechanism, thereby further improving the stability of towing.
