I purchased this cart for my furniture store. We sell a lot of heavy stone products. This cart is designed for up to 3,330 lb, according to the factory as I recall. After assembly I believe that rating is fair. I need a cart that can move a $ 5,000 stone table safely, that weighs 330 lbs. I chose this cart because it's much stronger than what I need, and other carts rate themselves higher than reality. The little amount I paid for the cart is much less than what I stand to lose if the table top is damaged. I am very happy with the quality of this product. It's well made with large strong wheels for any size job.
