The mod envelope from the author Meric was taken as a basis and completely redone by me.
All errors in the mod have been eliminated, new folding and unfolding animations have been updated, the sound has been updated, support for any bulk materials has been enabled, the mod allows you to overload not only concrete, but also any other materials (the material is poured from behind into a special container, and then we select using an arrow where this reload material).
The mod is very convenient when loading trucks in quarries / when extracting various bulk materials, when the loading point of the material shifts depending on the location of the material being mined, and the autodrive or course route remains in the same place (along with a parking space for the trucks).
Completely clean log without errors.
