The guy climbing the towers life depended on the hydrolic pipes not bursting.The last one , would it not be better it they just built a sloped ramp if they do this regularly .While the tower is impressive the last one on the coal cart is the real deal. The tower was built to climb and the machine had locking points added to climb it. Don't get me wrong, still needed balls of steel but the coal was real world where they could have built a better loading deck but that would cost more so use this that's just enough and when you get to the top just climb over that last lip 15 feet in the air, you'll be fine, it's not like steel on steel slides sometimes.
