Features

This 90 t capacity taxi crane has the strongest taxi load chart in its class and can easily manoeuvre on narrow job sites due to its compact design.

The GMK4090 crane features the new MAXbase outrigger system that expands options for crane set up on the job site.

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.

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

The new taxi model also offers excellent roadability and travel features. The GMK4090 can travel with a maximum 18.3 t counterweight, and within 12 t /axle it can transport up to 9.1 t 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.

The crane features compact dimensions, with a narrow 2.88 m width on 20.5 tyres, so it can easily access and manoeuvre within the tightest of job sites. It has a minimum tailswing of only 3.53 m 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 new 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.
