Grove GMK4090 Specifications

The Grove GMK4090 All Terrain Crane is a 100-ton (90-ton metric) lifting capacity taxi crane with an exceptionally strong load chart and can easily maneuver on narrow job sites due to its compact design.  

This model crane replaces the GMK4080-1 / GMK4100B and boosts more modern and efficient features that ensure a better return on investment for crane owners and was designed in response to customer demands for a lightweight, flexible taxi crane in this capacity class. The GMK4090 crane features the new MAXbase outrigger system that expands options for crane setup on the job site.

Additional Features:

• Best taxi load charts
• Compact dimensions
• Five-section MEGAFORM boom design
• Single engine concept with new Tier 4 Final Engine
• New comfortable carrier cabin
• Crane Control System CCS
• Swingaway & boom extension
• MEGATRAK suspension
• TWIN-LOCK boom pinning system

This crane is a popular all-terrain crane in Europe, and North America due to its versatility in applications, especially with rental companies.

The GMK4090 offers a 51 m (167 ft), six-section MEGAFORM boom that utilizes Grove’s TWIN-LOCK pinning system. Boosting its overall reach is a 9/15 m (49 ft) bi-fold swing-away jib that can be extended with a 6 m (20 ft) boom extension for a total jib length of 21 m (69 ft).

 The GMK4090 can travel with a maximum 18.3 t (20.2 USt) counterweight, and within 12 t (13 USt)/axle it can transport up to 9.1 t (10 USt) to the job site without the need for an additional transport truck. The result is a roadable crane with a strong load chart that also keeps transport costs low.

The crane features compact dimensions, with a narrow 2.55 m (8.37 ft) width, so it can easily access and maneuver within the tightest of job sites. It has a minimum tail swing of only 3.53 m (11.58 ft), so it stays within the maximum outrigger width. The GMK4090 also offers the new MAXbase feature as an option — this variable outrigger setting gives the crane more setup flexibility on the job site, especially when erecting it on irregular job site grounds, and also more capacity when compared with the 360° standard load chart.

The crane also features Manitowoc’s Crane Control System (CCS), an easy-to-use operating interface that has now been standardized across the company’s crane offerings and is featured on every new model.

This model is no longer in production and was replaced by the latest Grove GMK4090-1.
