But which one do you want?

Hello to all car fans I would have asked you a question, and I am looking for a good shear cart lifter but which is good from the quality, I had already tried a Heyner with 2 tons but the tilts too easily and has too much room for manoeuvre in the joints although the one is praised so high at Amazon but that is so bad that the thing is dangerous. I have seen on the Internet of SW Stahl there is a shear cart lifter but does what, the shear cart lifter should hal t so about 40cm can lift the vehicle up. Would be grateful for a reply. Greetings Amiwagen
