The new Grove GMK4090 all-terrain crane from Manitowoc features a compact design and was built to be road-ready and maneuverable. The 100-ton crane was developed in response to a need for a lightweight taxi crane. It is a generational update to the GMK4080-1/GMK4100B.
Andreas Cremer, global product director of Grove all-terrain cranes, said the crane’s load chart and compact footprint make it ideal for a variety of jobs, including 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,” he added.
The GMK4090 offers a 167-foot, six-section MEGAFORM boom that uses Grove’s TWIN-LOCK pinning system. Boosting its overall reach is a 49-foot, bi-fold swingaway jib that can be extended with a 20-foot boom extension for a total jib length of 69 feet.
The GMK4090 can travel with a maximum 20.2 tons of counterweight, and within 13 tons per axle, it can transport up to 10 tons to the jobsite without the need for an additional transport truck.
The crane features compact dimensions, with a narrow 8.37-foot width. Its minimum tailswing of 11.58 feet keeps it 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, when erecting on irregular jobsite grounds, and 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.
Manitowoc also has introduced the 90-ton GMK4080-2, which will not be available in North America. It has less counterweight to match the load chart of its predecessor, the GMK4080-1/GMK4100B.
