National crane supplier All Erection & Crane Rental Corp. has purchased 10 Manitowoc MLC300 crawler cranes, and Manitowoc has sold 50 crawlers in its next-generation crane lineup, according to sources at the companies.
The 330-ton crane, which debuts at the CONEXPO-CON/AGG show in Las Vegas, comes with Manitowoc's next-generation Variable Position Counterweight (VPC). Actuated by rack and pinion, the patented lifting technology responds to the load on the hook by sliding the counterweights back and forth as needed to maximize lifting capacity and reduce overall tail swing.
