How do you calculate a Loading Meter (LDM)?

2022-6-1 · So how do we calculate a loading meter? To do this, we take the following formula: length of the good X width of the good / width of the truck . As a default, we take a truck width of 2,4 meters. Loading meter calculation: An example. A pallet of goods is 0,80 X 1,20. This means we multiply 0,80 X 1,20 = 9.600 divided by 2,40 gives 0,4 loading ...
