New Grove AT, GMK4080-1

Grove's latest all terrain crane model, the new GMK 4100, will replace the existing four-axle model GMK4075-1. While retaining some of the design features of its predecessor, the GMK4100 will pick 7.3 tons with its six-section, Twin-Lock Megaform boom fully extended to 167 feet and set at a radius of 65.6 feet. With a hydraulic luffing jib and 19.7 foot extension, maximum tip height is 246 feet. This new model comes on the heels of Grove's launch of the GMK5275 in late November.

The GMK4100 can be configured in 'Taxi' or 'Maxi'modes. In 'Taxi' mode, the crane is within 13.2 tons per axle with 10.2 tons of counterweight, 49.2 foot hydraulic swing away, and 17.6 ton hook block. In 'Maxi' configuration, capability is increased by an extra 19.7 foot hydraulic swing away insert and counterweight to a maximum of 21.2 tons. Eight counterweight configurations are possible.

“The four-axle AT market is a busy one and, as always, we respond to market needs with continuous product development,” said Philippe Cohet, executive vice president of Manitowoc Crane Group's EMEA region. “The GMK4100 is very versatile, with compact dimensions, and is complemented with an excellent lifting chart and impressive reach.”

The new GMK4100 features a driveline modified from the older model, including the same ZF ASTRONIC transmission and 389 HP Mercedes-Benz OM 501 LA engine. However, the GMK4100 includes a two-step transfer case, to allow better agility at lower speeds.

The GMK4100 has a front overhang of only 5.9 feet, making it 10.3 inches shorter than the GMK4075-1. Total lengThis 43 feet.

The crane's air-conditioned cab is tiltable to an incline of 20 degrees, and its multi-function remote control allows for convenient operation of the outriggers and swing away jib. Other standard features include all-wheel drive and steer, MEGATRAK suspension, Grove's ECOS operating system and an EKS5 Light, load moment indicator.

A number of GMK4100s (known as the GMK4080-1 outside of the US) have been ordered by European customers, with the first two destined for Grohmann, a German haulage firm, according to MCG.
