Manitowoc launchs the Grove GMK6400-1

Following in the footsteps of its popular predecessor, the new crane retains the much-loved features of the original and adds notable new technologies for a stronger overall offering.

“The GMK6400-1’s predecessor, the GMK6400 was hugely successful and broke the mold for what was possible with a six-axle crane in terms of lifting power. So, with the new and upgraded model, we’ve kept that power that customers love and added more speed and flexibility. Visitors to bauma 2022 saw that for themselves and could fully appreciate the expanded capabilities of the new crane.”: so Andreas Cremer, Vice President of Product Management for all-Terrain Cranes at Manitowoc explained at the launch of the new GMK6400-1.

Like the GMK6400, the new GMK6400-1 has a maximum capacity of 400 t and a main boom of 60 m. Manitowoc has packed the GMK6400-1 with new innovations, including an improved hydraulic system with faster flow to provide quicker operating speeds and even smoother movement. Also added to the new 400 t machine is the Crane Control System (CCS) and MAXbase variable outrigger positioning system. 

“We knew we wanted to add CCS and MAXbase in the 400 t class and our Voice of the Customer discussions confirmed this,” said Andreas Cremer. “It was a complex process to incorporate these upgrades into the new design, along with the latest emissions-compliant engine. The result is an impressive heavyweight performer that delivers greater productivity and profitability for our customers.” 

The new engine on the GMK6400-1 conforms to the latest requirements for both Tier 4 Final Emissions Standards and EUROMOT 5. Driving both on and off-road is efficient, thanks to a best-in-class driveline that features a MEGATRAK suspension system and MegaDrive hydrostatic drive. As with the original GMK6400, the new GMK6400-1 includes the optional capacity-enhancing MegaWingLift. This self-rigging attachment can be deployed in less than 20 minutes and does not require an assist crane. It increases lift capacity by up to 70% on the main boom and by up to 400% when using the luffing jib. It makes the crane well-suited to applications such as bridge construction, wind farm work, or tower crane assembly. Manitowoc expects the crane to prove popular in infrastructure, general construction, energy, and industrial projects.

Maximum tip height for the GMK6400-1 is 136 m when fitted with its full complement of jib. With its impressive capacity and reach, the GMK6400-1 outperforms the competition in every category. Like the GMK6400, the GMK6400-1 can take on jobs that usually require a seven-axle (or even eight-axle) crane but inside a smaller overall footprint. It is an all-terrain crane that can lift up to 64 t on its 60 m main boom with MegaWingLift. This delivers a clear competitive advantage and ensures an accelerated return on investment for owners.
