“…Customers in China have a habit of preferring inexpensive and shorter-range microcar battery electric automobiles, yet plug-in hybrid SUVs. In contrast, United States customers desire cars for both battery electric vehicles as well as plug-in hybrid vehicles [22]. The top battery electric vehicle models are apt to have a longer scope, and plug-in hybrid vehicles tend to have a diminutive allelectronic scope in the United States compared to China.…”

Fuel cell vehicle machinery has substantial repercussions for energy policy and ecological protection. In the last era, China and the US have shown diverse progress in fuel cell vehicle manufacturing as the management's strategy issuances and enterprise's manufacture. Conversely, there are still roughly technical and expense difficulties impeding the commercialization of fuel cell automobiles. In this research, the position of China and the US fuel electric vehicles research method is analyzed comprehensively from various perspectives. Furthermore, the results of the fuel-electric vehicles are discussed and compared. The unique features and major concerns of each manufacturing segment are highlighted. Additionally, the performances of fuel cell electric vehicles perspective are reviewed on pre-existing works and information. With the combination of the fuel cell vehicle of business status and machinery performances, it is emphasized those technological developments in fuel cells and the optimization of the production methods for fuel cell structures are vital in manufacturing fuel cell vehicles.

“…Currently, the front end of a forklift is commonly equipped with a one-piece cantilever beam structure (overhanging beam) [5~8] , which is particularly prone to cause major safety accidents when the forklift is moving in the non-carrying state, such as stab wounds by the front fork to the head of pedestrians. As the market share of forklifts increases continuously, reports of safety accidents caused by the front fork unit are often seen [9,10] . The front fork unit has become a main cause of major safety accidents in the freight transportation industry.…”

In this paper, a detachable front fork unit is designed in response to major physical safety accidents caused by the forklift's overhanging end. The front fork in this unit is attached to the fork base by the screw-thread connection. When the forklift is traveling in a non-carrying state, the overhanging end can be removed to flatten the front end of the forklift, enabling the forklift to travel in a state similar to that of a car, which can greatly reduce accidental safety incidents caused by the forklift to pedestrians. The mechanical finite element of the front safety fork is also analyzed, and the results have shown that both the maximum stress and largest deformation, in critical working conditions, appear in the lower part of the fork base that contacts the fork frame. The maximum stress can be up to 2.5×10 7 N/m 2 , lower than the yield strength of the frame material. The largest displacement occurs at the tip of the front fork, which is 1.111 mm and satisfies the design requirement. This front fork unit is mainly designed for the fittings of forklifts driven by internal combustion engines or electric motors, which has no impact on forklifts' original operating efficiency and substantially improves the safety of forklifts. The proposed front safety fork unit is of great significance in enhancing the comprehensive performance of forklifts.

“…Lili et al 5) proposed a simulation to solve the problem of effective utilization with prediction methods of power control of electric forklift with Markov chain, fuzzy neural networks and BP. Xiong et al 6) studied the work efficiency and economic test in a real factory using 3.5 tonne forklifts comparing the proton exchange membrane fuel cell (PEMFCs) and lithium-ion batteries (LIB). The results show that the work efficiency of PEMFCs powered forklift is 40.6%, a higher work efficiency than from the lithium-ion battery-powered forklift.…”

The logistics industry has a vital role in supply chain management, which is considered an important industrial sector. Warehouse performance is a very important element in business. The forklift has a materials handling support activity, which affects warehouse efficiency. Specifically, we focus on the importance of forklifts in materials handling and their impact on warehouse efficiency. The objective of this work is to investigate warehouse operations by improving and solving forklift efficiency problems using the ECRS (Eliminate, Combine, Rearrange, Simplify) approach. In this case study, the warehouse manager identified three processes to enhance forklift tasks, aiming to reduce waste and minimize the total number of forklifts in the warehouse. Before the implementation of the ECRS technique in 2021, the warehouse had 30 forklift units with an efficiency usage rate of 49%. After the implementation in 2022, the total number of forklifts was reduced to 27 units, a decrease of 3 units. Additionally, the forklift efficiency usage significantly increased to approximately 66%. The implementation of the ECRS technique not only resulted in improved forklift efficiency, but also had a substantial impact on logistics cost. The company in the case study was able to save 504,000 THB per year in forklift rental expenses due to the reduction in the number of forklifts and the enhanced efficiency of their usage.
