Manitowoc has announced that it will launch a follow-up to the popular Grove GMK6300L all-terrain crane, which launched in 2010.The new 350-ton capacity model is the GMK6300L-1, and it will continue its predecessor’s legacy. In line with other Grove launches of recent years, the GMK6300L-1 offers innovations and capabilities. Several improvements have been made to the structural strength of the crane, which have improved load charts when compared with the GMK6300L. Customers will be especially pleased with the increased capacity when working at height, with improvements of up to 16 percent in the boom length ranges of 226 to 263 feet.

The GMK6300L-1 includes significantly enhanced load charts and Euromot 4/EPA Tier 4 final engines in the carrier and superstructure.

It features a maximum tip height of 394 feet when working with its full 263-foot main boom and 121 feet of jib. When lifting with the main boom, it can lift up to 15.4-ton at full height and can handle this within a 46 to 90-foot working radius, offering a flexible range for such applications as tower crane rigging. Overall capacities on the long boom will set a new benchmark for the industry.

The GMK6300L-1 is powered by a 580 HP Mercedes Benz (Euromot 4/EPA Tier 4 final) engine in the carrier that features improved fuel economy over its predecessor. This is paired with a reliable Allison torque converter transmission. A 280 HP Mercedes Benz (Euromot 4/EPA Tier 4 final) engine powers the superstructure.

Andreas Cremer, Manitowoc’s global product director for all-terrain cranes, took a moment to look ahead at the launch of the GMK6300L-1 while reflecting on the success of the GMK6300L.

“The GMK6300L, along with the GMK6400, effectively kick-started a new era of Grove all-terrain cranes, setting unprecedented industry standards in terms of reach, capacity and mobility,” he said. “The GMK6300L raced to sales of 100 units in just two years and 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.”

Like its predecessor, the GMK6300L-1 features Megatrak suspension, along with Manitowoc’s standard all-wheel steering. Its counterweight slabs and auxiliary hoist are interchangeable with the GMK5180-1, GMK5200-1, GMK5250L and GMK6300L, making it a particularly attractive investment for existing Grove customers.
