The Dock Platform
It could be the case that there are several different vehicles with varying dimensions at your distribution centre and they all need the same loading bay. Special transport like refrigerated trucks, will be higher for example due to the overhead refrigeration units and at the same time it could be the case that you are receiving goods from tankers, city vans you name it of course all variations are possible. A general rule is to determine the average floor height of both the lowest and the highest loaded vehicle. Also take into consideration the frequency of the different types of vehicles. Make your plans based on the 80:20 rule.
