Vibes

TRB. I did have some trouble with trolley 38 in that from time to time, the two back wheels got into a vibration which made it more or less impossible to continue to move forward. One had to stop and let the vibration die down before pushing on.

A combination, I should imagine, of not being able to have stays as the trolleys need to stack and the legs being a little too thin. Perhaps Sainsbury's, as part of its drive for green points, asked Wanzl to economise on the steel.

I need to check the record to be sure, but I had thought that Sainsbury's did not use Wanzl for trolleys, while Marks and Spencer did. See reference 3. Did the Sainsbury's trolley contract come up for renewal? Did their purchasing people get all kinds of jollies to Germany on the strength of that renewal? Perhaps to gmaps 48.4449735,10.2112013?

The telephone does seem to be quite good at close-ups - see reference 1 for another example. But it did wobble a bit with the shot of trolley 38 at reference 2. Of the twenty shots, only about a third had the trolley in reasonably sharp focus. Perhaps instead of the licking picking suggested in the previous post, I should spend the time reading the camera chapter of the telephone user guide, such as it is.

PS: reverse engineering the gmaps reference back to Wanzl is left as an exercise for the reader. As is working out why the nearby Danube has been given its Rumanian name - the Dunărea - in the middle of Germany. Sloppiness on the part of google's mapmakers or what?
