Caterpillar Launches Block Challenge

When Caterpillar plays blocks, they play BIG. "Stack" pits five Cat machines, including excavators and telehandlers, against a mountain of massive wood blocks. The object of the game is for heavy equipment operators to remove blocks one at a time from a stack of 27 and balance them on top of the tower for maximum height, without toppling the structure--using only their Cat® machines and attachments. #BuiltForIt
