29.04.2010 New Grove GMK6400 for Bauma

Manitowoc presented the world’s most powerful six-axle all terrain crane at Bauma 2010, the Grove GMK6400. The 400t capacity all terrain has a maximum main boom length of 60m and a maximum tip height of 136m. The Grove GMK6400 all terrain crane can be equipped with a Mega Wing Lift capacity-enhancing attachment, which allows the crane to offer significant lift capabilities, which are up to 35% stronger than similar cranes. The mega wing lift attachment provides extra support to the boom. A new Mega Wing Lift – superlift device which weighs around 10 tonnes with an overall height of 2.5 metres, transports separately from the crane.

The crane is also different from the GMK6300 in that it employs a single carrier mounted engine, unheard of on this size of crane. The Mercedes OM 502 Tier 4i (Euromot IIIB) eight-cylinder engine produces 405 kW at 1,800 rpm, powering a ZF AS Tronic 12 transmission.

The crane is equipped with a MegaDrive hybrid drive system for travelling at lower speeds. This gives the crane more efficient fuel consumption, a lower centre of gravity and longer lasting parts. MegaDrive powers the crane when it is accelerating to speeds of approximately 20km/h, and then the conventional drive takes over.
