I think that the biggest misunderstanding in this business is forklift de-rating. I believe that if a typical customer asks for a quote on a vanilla 5,000# pneumatic with a 189" triple mast and side shifter then they will be quoted on a base 5,000# capacity truck. Well most trucks that I know that are equipped that way de-rate to about 3700# capacity.
What I want to know is how does it get explained away when the truck is delivered and the customer looks at the capacity plate? The only things that I can figure is either the customer doesn't care, the customer doesn't understand or the dealership tells the customer that the 3700# capacity is only at full lift height and that it is OK to lift 5,000# at lower heights.
