Since the latter can be completely covered by the former features

Even if the above steps to complete the analysis, there may be several models while still satisfying the above requirements. At this requires attention to the following aspects:
① different models, different working efficiency, the number of trucks needed, the number of different drivers, will lead to a series of cost changes, see the section of this article discusses the performance evaluation on costs.
② If the stacker in warehouse Scissor Pallet Trucks operations, different models in different channel width required to enhance the ability to have differences, which will bring about changes in the layout of the warehouse, such as cargo storage volume changes.
③ models and the number of changes, fleet management and other aspects will have an impact.
④ different models in different market holdings, its after-sales support capabilities are different, for example: low driving three-car pile high and high driving three belong to the narrow channel Stacker forklift series, can be in a very narrow channel (1.5 ~ 2.0 m) to complete the stacker / forklift, pick up. But the former can not raise the cab, so poor operating perspective, the lower the efficiency. Since the latter powered pallet trucks can be completely covered by the former features, and performance is more superior, and therefore beyond 4 to 5 times the sales in the European market, the latter than the former, in China reached more than 6 times. Therefore, most of the suppliers are focused towards the development of a high driving three cars piled high, and the low three-stacking forklift driver is only used in small-tonnage, low lift height (generally less than 6 meters) of operating conditions. In the small market sales, the number of its service engineers, engineers experience, service capabilities, such as parts inventory levels will be relatively weak.
