Hello, everyone knows the , with unscrewing truck wheels the wheel nuts are usually extremely tight . If you don’t have a huge impact screw and a powerful compressor , the wheel nuts are usually very hard to unscrew . Then on the wheel nut key a 2 meter long tube is plugged up , one holds the evening-advanced construction , the other climbs up to the end of the extension tube and tries to loosen the wheel nuts by ripping . n with a loud bang and all those involved must take care not to hurt themselves. Now I have found this torque amplifier – wheel wrench when searching in a spare part/workshop catalog. Who has experience with this ? works that, the things do what and keep what they promise. Find on the Internet offers from 60,- € to 5200Nm. That should be enough to solve, or still lacks the blow. All advertise with industrial quality, At specialized retail costs 220,- € . But are not all brands like Gedore or Hazet. But as asked, a single man gets the wheel nuts loose without hurting himself. Thank you for your advice. Mathias
