Grove launches new best-in-class GMK4090 all-terrain taxi crane


Responding to customer demand for a lightweight, flexible taxi crane, Manitowoc has introduced the best-in-class Grove GMK4090 for purchase across the globe.

The GMK4090 is an upgrade of the GMK4080-1/GMK4100B – a popular all-terrain crane in Europe, due to its versatility in applications.

The new crane has a 51m (167ft), six-section Megaform boom that utilizes Grove’s Win-Lock pinning system. Boosting its overall reach is a 15 m (49ft) bi-fold swing-away jib that can be extended with a 6m (20ft) boom extension for a total jib length of 21m (69ft).

The GMK4090 also has compact dimensions. It boats a narrow width of 2.55m (8.37ft), so it can easily access and maneuver in confined spaces within applications. It has a minimum tailswing of 3.53m (11.58ft), so it stays within the maximum outrigger width.

The crane also offers the new Maxbase feature as an option. Maxbase is a variable outrigger setting that gives the crane more setup flexibility in its working environment, especially when it is being erected on irregular jobsite grounds.

The new GMK4090 crane is strong, and thanks to its excellent roadability and travel features, it can keep transport costs low. It can travel with a maximum of 18.3 metric tons (20.2 US tons) counterweight, and within 12 metric tons (13 US tons)/axle, it can transport up to 9.1 metric tons (10 US tons) to the jobsite without the need for an additional transport truck.

In addition, the new model features Manitowoc’s Crane Control System (CCS), an easy-to-use operating interface that is standardized across the company’s crane product line, and is featured on every new model.

Manitowoc has also released the GMK4080-2, a similar crane with an 80 metric ton (90 US ton) capacity. Unlike the GMK4090, the GMK4080-2 will not 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, to match the load chart of its predecessor, the GMK4080-1/GMK4100B.

“The GMK4090 has been designed with flexibility and maneuverability as main focuses,” he said. “With its best-in-class taxi load chart and compact footprints, this crane will be ideal for a variety of jobs, such as general construction and plant maintenance work. Various counterweight options also give it versatility in roading, which can increase efficiency and return on investment for many owners.”
