At lower volume levels the hand truck method has lower costs because of low fixed costs. As volume increases, cost differences decrease until, at a volume of about 34,000 hundredweights (at the low output rate), costs for the two methods are equal. For the high output rate, this point is reached at about 78,000 hundredweights. Beyond these points costs are lower for the conveyor method. The fork truck method has higher costs at all volume levels.
