I was just wondering if anyone can explain the model numbers liebherr uses for their excavators. Most times, you can relate the model number to the weight of the machine, but with liebherr ??????? Just curious
I don't know the origins of the scheme, and it has been rather inconsistent, and dependent on where the machine was made (i.e. the Liebherr America machines of the 1970s and 1980s had a different 9x5 scheme) For the 9xx models: First digit is just 9 Second digit is size class; 0 = 20 tons, 1 = 24 tons, 2 = 27 tons, 3 = 36 tons (no current model made for this size), 4 = 40-45 tons, 5 = 50-60 tons, 6 = 67-80 tons, 7 = 85-105 tons, 8 = 120 tons Third digit is generation (kinda, they also have sub-generations): 2 = first gen, 4 = sencond gen (with sub generations denoted by a letter, current among bigger machines), 6 is the newest generation for some models Example: R 944 C is the current generation 45 tonner. There are a ton of exceptions to this rule (such as the R 900, the R 995, and the R 996), it's really inconsistent. For the 9xxx mining shovels it's much easier. The first digit is 9, and the next 3 digits are the weight in tons. Eg. R 9350 is 350 tons.
Also, for the 3xx models: The 313 is about 14 tons, and the 317 is about 18 tonnes. I have had a limited but positive experience with Liebherr machines, but they aren't too popular here, at least in Ontario. That's probably due to the rather limited dealer network - they only have one proper dealer in Ontario, that's located in Burlington. The Burlington dealer seemed helpful when I went there (once), but I wouldn't want to have to drive all the way to Burlington (and probably wait ages for parts to come from France and Germany) when things go wrong.
That's why i asked. There is a big sob 964 i think working on Rymal Road. So it must around 70 tonne, 2nd gen. huh.
Yeah, something like that. If it's a 964C, then it is the current model. Don't ask me on what the difference is between a 964C and 964B is, because I don't know, other than the fact that the C is a little newer than the B. P.S. To add the the confusion, the original 964, the 964B, and the 964C all look identical and none of them even have any mention painted on them if they are original, B, or C. They are all just labeled 964.
b= non computer control engine tier 2 c= computer control engine tier 3
In other words, place a higher value on the B models when buying used for superior reliabilty (outside of California). :Banghead
The model numbers bear absolutely no relationship to the size or weight of the machine. The final weight is determined by the build spec. They are all built to order, not for stock, and the customers needs decide the build. The same base excavator could be purpose built for demolition, rehandling,dredging etc. Models on wheels, or "rubber ducks", are built in Kirchdorf, Germany while tracked machines are built in Colmar, France. Ducks have an "A" prefix and tracked machines have an "R" prefix. Numbers fade into insignificance when you look at dozers, built in Austria, and sold in the USA as John Deere, and tracked and wheel loaders, also built in Austria. The only place in the Liebherr group where numbers have any meaning is the crane products - lifting capacity is indicated in the number. I worked for Liebherr for many years and have visited these factories on training courses.They are very impressive, especialy Colmar, where the mining machines are made.

You can order custom machines, but don't tell me that you make a 3 tonne that you call a 984 or make a 800 tonne 906. The models numbers for the are related to size (though Liebherr does like messing up the numbers and changing the scheme from time to time). Liebherr makes zillions of configurations of ever model, but all machines with the same model number are roughly around a similar size. The Liebherr website itself provides a chart relating model numbers to size and weight... see the excavator model list on Liebherr's website.
So if i wanted a 20 tonne unit for basements, and i wanted it yesterday, how long would i have to wait to get it, and what would the number be?
it is a common misconception that there is some relativity in the numbers. The numbers have NEVER bore any relationship to size. Even the earliest of the "9" series, for example, the R901, was not a 1 ton machine - it weighed about 15 tons. And the R941 weighed about 28 tons. Wheel loaders are even further from the scale. the largest - L586 weighs about 35-37 tons, depending on tyres, bucket, guards etc. PR764, their largest dozer, about about 50 tons. The same absense of logic carries through the tracked loaders and pipelayer range. I have known contractors put an R954 on to a site as a 55 ton machine, where the machine weighed 46 tons! The only clue that has any real meaning is in the LETTER designation, A being rubber duck,R being tracked excavator, PR being dozer, L being wheel loader,LR is tracked loader, LR is tracked loader (but LR is also a crawler crane type!), LTM is a mobile crane ,T is mining truck. While they seem to use no sense at all with the numbers, they put a lot of sense into the machines. They are the most advanced machines on the market, with superb build quality.
I have to agree there. I operate a 964c in se configuration, weighs about 76tons and very well built and powerful. Best built machines on the market, no monkey metal like 99% of other manufacturers
Rolo70 I have just purchased a 944c HDSL with 4500 hrs on. What's your thoughts on liebherrs as far as performance/reliability we have never run one before but the build quality looks top notch. Regards Steve
