The largest crane of Mayer from Burgberg (DE) is this sharp Tadano ATF 400G-6, this was the first crane of this type to be deliverd to the client in the world and has year of manufacture 2011. In the begining of 2020, this crane was replaced by a newer crane of the same type.
The undercarriage is powered by a Mercedes-Benz OM 502 LA, an 8-cylinder diesel engine with a power of 480 kW (653 hp). The crane has a 12 x 8 x 12 drive line, four axles are driven and all axles are steerable.
However this the first deliverd crane is, has the crane serial number 2. The crane with number 1 was used for many factory tests and was sold later to Romania.
The crane has in transport mode a length of 17.9 meters, a 3 meter breadth and a 4 meter height. The transport mass is around 72 tonnes.
The counterweight frame remains here to the superstructure. This is the easy version, the crane has no luffing jib.
A few weeks later I could take more photos of the crane from the other side on Mayer's yard.
The 5-part main boom has a 15 meter base length and extends four times to a total length of 60 meters. Later models of the ATF 400G-6 could be fitted with a boom guying system.
The outrigger base measures 8.9 x 8.5 meters.
The first counterweight, outrigger pads and some lifting gear is transported on this modified 3-axle tipper trailer. the trailer is pulled by various trucks, like here by the Iveco Stralis 560.
The maximum counterweight weights 138 tonnes and has a 5.6 meter tailswing. 80 tonnes of these 138 tonnes, do exist out of these 10-tonne slabs which are stacked in two towers.
Mayer only owns 12 meters of fixed jib, that was during taking these photos only used once.
A very sharp and tough crane, that is mainly used in the southern part of Germany in the Allgäu region.
