The Gedore 7 R XL ratcheting wrenches are made in Germany and go up to 36mm. The 638mm long wrench must pass the relevant DIN standard. What makes you think the well proven UR20 ratcheting mechanism can't handle the torque ?
Gedore actually doesn't advertise what industry std their ratchet wrenches meet. If they met DIN 899/ISO 1711-1, that would be impressive indeed. But they are single pawl fine tooth ratchets.
As has been said many many times before, I think it's wise to not use these wrenches to break fasteners free. Use a proper box wrench. In smaller sizes, I think you can generally "get away" with breaking stuff free with your ratchet wrench. But the recommended tightening torque (let alone the actual reverse torque reqd) is SO high for large fasteners, no ratchet wrench, no matter how well made, can meet that requirement. And I think mnanufacturers generally feel that if a tool fits on a fastener, it should be strong enough to loosen that fastener, or tighten it to the std industry torque. Repeating myself, this is why we don't see 19mm 1/4" drive sockets. The 1/4" drive would shear off before the req'd torque was achieved.
Just so no one thinks I'm bashing Gedore, I got to read up on their ratchet wrenches. While I think Snap On (in the US anyway) offers better value for money (finer ratchet, very likely stronger due to dual pawl arrangement, option for flank drive plus open end, super long std pattern), the Gedore feature a very tight open end, very good quality steel, and what looks to be a very easy to repair ratchet mechanism. This last point is a serious selling point since some other wrenches, Snap On's high performance series for example, are not user serviceable.
So if you believe what I'm saying to be true (essentially, ratcheting box wrenches are inherently weak) one would be well served to get ratchet wrenches under a functionable warranty or with easily replaced guts.
