Grove GMK6400 - MSG

MSG from Kehl (DE) used this Grove GMK6400 in Ravensburg (DE) by the disassembly of two tower cranes. MSG means Mohr, Scholpp and Gutmann - three well known names in the German crane- and transport world.

It is a 400 tonne crane on a 6 axle crane carrier. The GMK6400 was introduced on the Bauma 2010 for the first time in the MSG colors.

The outrigger base measures 8.7 x 8.5, or half 8.7 x 6.3 meters.

The crane carrier is powered by a Mercedes-Benz OM 502 LA, an 8 cylinder diesel engine with 551 hp. 4 of the 6 axles are driven, all axles are steerable.

Packed has the crane a 17.3 meter length, a 3 meter breadth and a 4 meter height. The transport mass is around 72 tonnes.

The crane was here erected with 95 tonnes of counterweight, existing out of a 15 tonne base plate and 8 slabs with each 10 tonnes. The full counterweight weights 135 tonnes. The counterweight has a 5.86 meter tailswing.

The main boom of the crane has a 15.39 meter base length and extends four times to a 60 meter length. Optionally this crane can be used with a sideway superlift boom guying system (Grove mentions it MWL). The crane can put the boom guying system in one lift onto the crane carrier and can install it himself to the main boom.

The crane was used here with a 55 meter luffing jib. The luffing jib has a 25 meter base length and can be increased in 6 meter steps to a full length of 79 meters.

Typical Grove; the execution of the luffing jib with a single strut and the boom foot with the kink.

Here is the 256 HC base tower section of the Liebherr 280 EC-H lifted out of the building. This tower section weights 7.8 tonnes.

The main boom of the Grove is here 30.1 meters extended.

A very sharp crane!
