Moin, we want to buy a better tyre montage machine in our hobby workshop, because the current maximum 19-hours spans from the outside and also has no auxiliary arms. We have more frequent low-cross section tyres with which we really torture ourselves or sometimes runflats with which we then have to drive again to another workshop. However, there is no daily mass handling planned and we don’t want to spend more than 2,000, – we also don’t want to. Found I needed hardly anything and new in the Price range the 3 following: – Twin Busch TWX 98 – DEMA BL 505 – Trainsway ZH 650 (would be used in the surrounding area cheaper) The Twin Busch has 2 auxiliary arms with their own pneumatics, but the mounting head goes away to the side. The other two look very similar from the equipment of the Twin Busch TWX 36, which however costs at TB 750,- Euro more. Of course, all are produced in China, but at Twin Busch I somehow go from the best spare parts supply g. Does one know these devices here and are there possibly any qualitative differences? Or are the actually all the same and possibly needed spare parts also available everywhere on the free market? Experience with such devices I do not yet have yet. Which kind is better when working? The ones from TH with 2 individual auxiliary arms or the ones with only 1 arm on which but more aids are installed? With the TB you could also plug on the 2nd arm and with adapters the rim runt Squeeze or just lift the tire. Greetings, Lars
