This might cheer you up; )

I see that none of their ropeshovels have been posted, gotta change that! ;)

This old 475 was displayed at a vintage machinery meeting in Sweden last summer.

Another 475, this one with the hydraulic dipper tilt being shown at a machinery exhibit in Stockholm about 1997.

The first ropeshovel made by Åkerman, the model 300 was a 3/8 cu.yd brought out in 1939. The first version of it was more or less a copy of the Rapier 4½0. This is a later version with the style of undercarriage that all Åkerman ropeshovels would sport.

Thank you very much Jeremy! :D

I have had this sick and twisted urge to collect mostly everything that I could when it comes to ropeshovels :mrgreen:

These two pictures were taken at the Skyttorp machinery museum in Sweden last summer. About a dozen different shovels and bulldozers were driven during the day. The largest piece of machinery being a 54-R&B that is being refurbished(Yes I have footage of the Ruston engine :mrgreen: )

"Within their weight classes I never knew anything that could out-dig them in hard ground. The H series were often referred to as slow but that depended on the material type. On an easy dig Cat's 200 series would run rings round em but get into something that required real muscle and it was very much the other way round. H25 was the worst in the range in terms of reliability but it could dig material that a 245 could barely touch"


I'm afraid that in my experience, in terms off digging power there was never the clear water between Ackerman and the rest that diehard Ackerman men always claim. What Ackermans did have were better designed buckets which seemed better in some conditions. As for run rings round the equivalent 200 series, that would be more down to the operator rather than the machine. IMHO.

Saying that though, I did like the Ackermans to operate. The first one I got to pilot was a H14 with a quick hitch. This quick hitch was operated by a toggle on top of the right hand console, somewhere near your elbow and easy to knock. Which I did on one occasion, and put a full bucket of hogging into an eight legger, bucket and all.

Both very interesting posts. Operator is key of course and the importance of bucket design often underestimated.

I don’t know if All Akerman models offered greater digging power than Cat’s 200, or that all 200s offered faster cycle times than the equivalent H-Series.

A company I used to work for was a big 200-Series user. We didn’t have 229 or 231, but did run 215, 225, 235 and 245. These proved to be good machines and some very good. For example, 235B was better than the C and D best of all, at least for us.

Akermans offered to demonstrate their H16D and taken for a week on a site with a couple of 235s, both with approx. 2.4cu.m, albeit different in design as Cat and Akerman buckets always were. That H16 had lost before it even arrived. Our operators simply weren’t interested in it and neither was the boss really, and only took it to have a free machine. His words were on the lines of, 'You might not notice it being slower than the 235, but at the end of the day the 235 will move more'. Key words there are you might not notice, because it certainly wasn’t obvious.

I think the H16 and 235 were fine machines in their day, but very different products.

H16 was more powerful than a 235, but it’s all relative because although I would never say that a 200-Series couldn’t dig, in all fairness, none of them was a real heavy hitter. How powerful an H16 was in comparison to for example, an O&K RH20, I don’t know.

At 65t, not much got in the way of 245, but certain competitors – including the H25C/D – could out dig it in difficult to extract materials. In easier ground, the H25 was for a given operator, slower.

The 215's and 225's weren't embarrassingly slow by today's standards, but the 235's were quite slow cycling. However on a short stick, even with a big bucket they had some fierce breakout. I suppose the Ackerman vs the rest debate will never be definitively answered. Interesting you mention O & K, their construction sized machines were never common over here, but they were a solid machine, with good breakout. The mistake Ackerman made, IMO, and bearing in mind that they did sell well at the time, was thinking that breakout was everything, and as with most other things, the Japs started building the machines that the majority wanted.

Came across this today it was at the same place as the 580BT that I stripped the bits off; I think she is an H3? The owner said that she had been modified for use in a forest, the undercarriage had been raised and he had added the extension to the dipper arm, a lovely little machine that he started and gave Julian and myself a demonstration. :thumbup:
