Question:

About the load reaction?

In a crane will the load acting will me more on movement than in stationary lifting?

Answer:

Very interesting questionI've never ran into that problem but after thinking it over it reminded me when you read some recipes for making a marinade for meats or veggies that calls for any acid like vinegar or lemon juice it says to put it in glass not in a metal bowlSo that sounds like what could cause a reaction in the aluminum foil food packagesSo next time try using parchment paper food packages for acidic foods and bake it in the ovenYou just place the food on one side of the paper then fold the paper over and crimp the edgesThen poke a couple vents in it and bake on a cookie sheet.
If the load on the crane is caused, by motion of the crane, to accelerate, then that will change the effective load compared to the static load value during such acceleration.
