Manitowoc is launching a successor to the hugely popular Grove GMK6300L all terrain crane, which has been available since 2010

The new 300t model is the GMK6300L-1, and it will continue, says the company, its predecessor’s legacy, bringing new levels of performance to the six-axle category.

Changes to the structural strength of the crane have improved load charts by over 7% compared to the GMK6300L. Improvements at height are even greater: the advantage is over 16% in the boom length range of 70–80m.

Maximum tip height is now 120m when working with its full main boom and 37 m of jib. The main boom can lift up to 14t at full height and can handle this within a 14–28m working radius, offering a flexible range for such applications as tower crane rigging.

The GMK6300L-1 is more fuel efficient. It is powered by a 430kW Mercedes Benz (Euromot 4/EPA Tier 4 final) engine in the carrier paired with an Allison torque converter transmission. A 210kW Mercedes Benz engine powers the superstructure.

Like its predecessor, the GMK6300L-1 features Megatrak suspension and Manitowoc’s standard all-wheel steering. Its counterweight slabs and auxiliary hoist are interchangeable with other GMK models, making it an attractive investment for existing Grove customers.

“The GMK6300L effectively helped kick-start a new era of Grove all-terrain cranes” said Andreas Cremer, Manitowoc’s global product director for all-terrain cranes.  “To date more than 400 have been delivered. With its significantly improved load charts and specifications, we expect the GMK6300L-1 to prove just as popular.”
