The actual CAT 587T Pipelayer is beast of a machine, weighing in at a whopping 117,000 pounds. The boom reaches over 30 feet into the air to lift up to an ever-greater 202,000 pounds! There's a whole list of the specifications here, which I found very interesting.
The piece that you'd be ordering comes in 1/50 scale, a more manageable size. Manufactured by Norscot, it's sure to be a great quality piece.
