Grove GMK5225

Mobile Crane

Manitowoc rolled out to a North American audience the GMK5225 during Conexpo-Con/Agg 2008. Specifically designated in North America to reflect their maximum rated lift capacities in 225 U.S. tons, the GMK5225 can achieve tip heights of 331 feet. The GMK5225 featured the standard Mercedes engine, but a Cummins engine option is available. The option is to appeal to crane owners in the U.S., as will the optimum on-road/off-road performance that comes from the engine combined with the Allison transmission and two-speed transfer case.
