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.

causing the safety factor is small

 broken rope accident

     Accident is the broken rope hoisting rope or hoisting rope breaking weight loss caused by the accident . Broken rope is a common one accident. Broken rope pull off mostly overloaded lifting rope ; ceiling switch failure caused from excessive volume pull off the rope ; bias caused by pulling the rope hanging oblique squeezed off ; or because of the continued use of the rope over the standard retirement caused by broken rope .

     In addition, due to the lifting wire rope buckle fracture caused by such accidents are very common. powered pallet trucks  with Shengkou rope buckle fracture mainly because inappropriate choice of specification , causing the safety factor is small ; Shengkou angle caused by too much or lifting its tension exceeds its limit and breaking pull off ; or rope buckle with heavy angular plus gasket between unprotected edges cut the rope caused by heavy buckle . Hoisting rope breaking caused mainly due mostly lifting angle is too large (> 120 °) so that the tensile strength exceeds the limit while hoisting rope to pull off .

     Hanging crane fall accident occurs mainly in the lifting mechanism extract winding system , in addition to rope off , decoupling, off the ropes and off the hook , but each hoisting rope is fixed at both ends is also very important , such as safety rope on the drum circle number is guaranteed over three laps , rope wedge plate fixed or fixed structure on the reel is safe reasonable. Another rope off the tank, off the wheel accidents also cause loss accident.
