Hi Goodie,
Based on all the discussions, do agree that it is not a good idea to have a man-down truck for 13 meters. Usually, a person vision and judgement is good up to 6 meters.
And if you want order picking, then a man-up will be the best. Operator goes up to 13 meters, pick up the goods and then he can go to another location to pick other items.
PAPA is right Jungheinrich had not sell a single ETX515.
