At Bauma 2019 Manitowoc launched an impressive new unit in the five-axle category and two new three-axle models. Andreas Cremer, global product director for all-terrain cranes at Manitowoc, said the launch of the new models underlines the company’s increased speed of product development under The Manitowoc Way and its ongoing commitment to building cranes that offer outstanding return on investment.

With its 78.5 m boom the GMK5250XL-1 has the longest main boom of any five-axle all-terrain crane and combines that with the best lifting capabilities in the industry. As with all Grove all-terrain cranes, it features Megatrak suspension and the Twin-Lock boom pinning system. It is also available with the MAXbase variable outrigger function for added versatility on the jobsite.

Options for the GMK5250XL-1 include the VIAB turbo retarder clutch, which first featured on the original GMK5250L. The VIAB unit enables wear-free starting and braking, enhancing maneuverability and operator comfort. In addition to its high-performance features, the crane delivers a compact footprint, making it ideal for use in crowded or urban areas.

Rule of three
In the three-axle category, the GMK3060L sets new standards of excellence and includes a powerful, seven-section MEGAFORM boom with 48 m of main boom and a maximum tip height of 65 m when working with its full jib. For consistency and control, the 60 t crane features Manitowoc’s Crane Control System with boom configurator for fast and efficient set-up. With its compact carrier, the GMK3060L can squeeze into tight locations, again making it a great option for downtown job sites or congested projects.

Next to the GMK3060L is the new GMK3050-2, an update of Grove’s long-running three-axle offering, the GMK3050-1. It offers a 40 m main boom, fast operating speeds and a single counterweight configuration for ease of use. It’s engine and design have also been updated to meet the latest requirements of Euromot 5 (which also covers both Tier 4 Final and Tier 3 regulations in the U.S. and the rest of the world).

Both the GMK5250XL-1 and GMK3060L offer the most compact footprint in their class, and both have best-in-class load charts when configured in taxi-mode, at 12t per axle.
