The Manitowoc 16000 lattice-boom crawler crane, with a standard rated lift capacity of 440 tons, is now available with the company's MAX-ER attachment, which can provide up to 256 tons of counterweight for the machine. The MAX-ER allows longer boom lengths and added capacity at any given radius, says Manitowoc. Standard boom length for the 16000 is 315 feet, but the MAX-ER allows 394 feet of main boom.
