The person who delivers bottled products such as beverages or liquor carries hundreds of boxes a day by truck. We recognized the situation in which delivery people stack heavy boxes up one by one on the cart even with their busy schedule and wheel the cart with one hand but without the other hand which is used to hold the boxes not to be collapsed. Fork Cart & Box loads boxes on the cart using the shape that forklift truck loads goods on itself as motif. Using this function, delivery person don't have to stack boxes one by one. Also the boxes don't slide from the cart, and it gives them balance and security.
