New all terrain crane from Grove features compact design for easy road travel
Manitowoc has introduced a new all terrain crane, the GMK4090. Dubbed a “taxi crane,” it features a compact design that emphasizes roadability and maneuverability.
“The GMK4090 has been designed with flexibility and maneuverability as main focuses in accordance with our customers’ needs,” said Andreas Cremer, global product director of Grove all-terrain cranes. “With its best-in-class taxi load chart and compact footprint, this crane will be ideal for a variety of applications. 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 meter (167 foot), six-section MEGAFORM boom that utilizes Grove’s TWIN-LOCK pinning system. Boosting its overall reach is a 15 meter (49 foot) bi-fold swing-away jib that can be extended with a 6 meter (20 foot) boom extension for a total jib length of 21 meters (69 feet). It can travel with a maximum 18.3 metric tons (20.2 US tons) of counterweight, and within 12 metric tons (13 US tons) per axle, it can transport up to 9.1 metric tons (10 US tons) to the jobsite without the need for an additional transport truck. The distance between the front and rear axle groups was extended beyond the 2.4 meter (8 foot) minimum requirement for U.S. bridge laws.
The crane features compact dimensions, with a narrow width of 2.55 meters (8.4 feet). It has a minimum tail swing of only 3.5 meters (11.6 feet), so it stays within the maximum outrigger width, unlike other cranes in this segment that require extended tail-swing clearance. 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. MAXbase also offers greater capacity when compared with the 360° standard load chart.
The GMK4090 features Manitowoc’s Crane Control System (CCS) that has been standardized across the company’s crane offerings and is featured on every new model.
The crane was introduced to customers and dealers at the company’s Crane Days events in June.
