I have 3 very heavy duty dollies that are approx. 40" x 50" and capable of carrying thousands of pounds. I use them to store my heavy tractor implements for my New Holland 45 HP tractor. Standard wood pallets fit nicely on them. They are close to 100 years old from the old Torrington Co. They would make a great Coffee Table with a piece of thick plexiglass or safety glass, sealed with a clear poly finish or painted or even as is. They are made with welded angle iron frame and thick oak boards and steel wheels 2 of which swivel. The price is for each one.
