There are many different factors which would affect the amount of weight that the branches of a tree could support; a maple tree has a stronger branch than a pine tree, for example, and a larger tree has stronger branches than a smaller tree. If we were to examine a particularly large, strong tree, the branches could support thousands of pounds.
