Hello Preben1991,
the axles you are asking for are reinforced indeed. The main difference between them and the previous ones is the structure of the cast iron. The old version is made from cast iron in which the graphite has a lamellar structure. Because of the notch effect at the end of the lamellea this structure typ is not that strong and it does break brittle. The GGG stands for "Globularer Grauguss" what means nodular cast iron. The european standard is "GJS", "GGG" is the old German standard. The main difference is that the graphite has an spheric structure and therefore it has no notch effect what makes it ductile. So as a result they really are stronger and they have a different fracture behaviour. When they did come up exactly I can't say, at least the last build years should have them. Weak axles are some problem at the bigger A-Series, such as the A60 on which the axles break some times. For me I have to say I own an A55 first series, Number 267, build year 1973. It has done around 11.000 operating hours with a massive frontloader which is reinforced by some 8mm steel plates. I can promise you this thing had lifted some tons. It still has the original axles and they never got a crack somewhere. The main problem are the gears in the gantry and trust me the pivot is on long term the much weaker part.. I hope you got what it's on with it, Just ask if you want to know more. Greetings from Germany Julian

Very interesting, thank you.
I know the axles was a problem on the a55 here in Norway, with all the forestry equipment back in the day.
