Grove launches GMK4090 taxi crane

6 November 2017 by Sotiris Kanaris


Manitowoc has introduced a new all terrain taxi crane, the Grove GMK4090, in response to customer demand for lightweight taxi cranes in the 90t (100USt) capacity class. It represents a generational upgrade over the previous GMK4080-1/GMK4100B.

The GMK4090 offers a 51m (16 ft), six-section Megaform boom that utilizes Grove’s Twin-Lock pinning system. Boosting its overall reach is a 9/15m (49ft) bi-fold swing-away jib that can be extended with a 6m (20 ft) boom extension for a total jib length of 21m (69 ft).

The new taxi model can travel with a maximum 18.3t (20.2USt) counterweight, and within 12t (13USt)/axle it can transport up to 9.1t (10USt) to the job site without the need for an additional transport truck. “The result is a taxi crane with a strong capacity that can keep transport costs low,” said Manitowoc.

The crane features compact dimensions, with a narrow 2.55m (8.37ft) width, so it can easily access and maneuver within the tightest of job sites. It has a minimum tailswing of 3.53m (11.58ft), so it stays within the maximum outrigger width.

The new crane also features Manitowoc’s Crane Control System (CCS), while the MAXbase feature is optional.  

Manitowoc has also introduced the GMK4080-2, a similar crane with 80t (90USt) capacity. The GMK4090 will be released globally, whereas the GMK4080-2 won’t be available in North America.

Andreas Cremer, global product director of Grove all-terrain cranes, said the GMK4090 and the GMK4080-2 models are essentially the same crane, but the GMK4080-2 carries less counterweight.
