Grove GMK – collective page of the all-terrain cranes: American maker, part of Manitowoc since 2002, lifting capacity in tonnes coded in the type name, 205 to 420 kW
This page gathers the Grove GMK range, all-terrain cranes from the American maker Grove, founded in 1947 in Shady Grove, Pennsylvania, and part of the Manitowoc Crane Group since 2002. GMK denotes the all-terrain crane range; the following number roughly gives the maximum lifting capacity in tonnes – GMK4080 about 80 tonnes, GMK5220 about 220 tonnes, GMK6400 about 400 tonnes – the suffix after the hyphen the axle-count sub-variant or development step, and L an extended-boom version.

The register lists here 48 versions with outputs from 205 to 420 kW, displacements from 6,370 to 21,900 cm³ from six- to eight-cylinders, operating weights from 23,750 to 77,000 kg against gross weights of 24,000 to 72,000 kg and widths from 2,500 to 3,000 mm; torque is recorded for a handful of entries at 580 to 2,600 Nm at 1,800 rpm.
Alongside Liebherr and Tadano, Grove is one of the leading suppliers of all-terrain cranes, and with the GMK range covers the spectrum from the compact two-axle crane to the large crane for industrial and wind-turbine assembly work; the cranes drive to the job site on public roads and then work off-road there without a separate low-loader.
On used examples, engine and crane-gear operating hours, the condition of the telescopic sections, cable drums and outriggers, the tightness of the hydraulic cylinders, and rust on the frame and boom segments all count; parts and service run through the Manitowoc-Grove network.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
