1. The market prospect of China's electric forklifts is vast The modern logistics industry has now become a pillar industry of the national economy in the new century. It not only constitutes the carrier and foundation of modern supply chain and value chain management, but also organically connects production, circulation and consumption, accelerates the process of social reproduction, and completes the commodity from the production field with the fastest speed, the best time and the optimal combination. The transfer process in the consumer sector minimizes the cost of circulation. The forklift, which is known as the "God of Handling", plays a huge role in the field of logistics. Electric forklifts will become more and more popular among users in recent years. However, in general, the market share of electric forklifts is only 21%, which is quite different from the ratio of electric forklifts in the European and American markets. This shows that China's electric forklifts have broad market prospects.
2, electric forklift has obvious advantages of energy saving and environmental protection Many advantages of electric forklifts In addition to the characteristics of low noise and no exhaust emissions, in fact, the use and maintenance costs of electric forklifts have great advantages compared with internal combustion forklifts.
Cost of use: The cost of electricity consumption is much lower than the cost of diesel or petroleum liquefied gas. If we compare a forklift with a load capacity of three tons, the diesel consumption of a diesel internal combustion forklift for each shift (according to 40 litres of diesel per shift, the vehicle consumes 5.5 litres of diesel per hour for 60 VDI cycles) The cost is about 196 yuan (4.9 yuan per liter of diesel). And if a three-ton electric forklift uses an 80-volt 500AH battery (the battery's storage capacity is 8×500=40 kWh), operate one shift (80% discharge, according to 120% supplementary charge ratio, need to consume The electric energy is about 40 degrees. The cost is about 140 yuan (calculated according to the current industrial electricity consumption of 3.5 yuan per degree). You can save 56 yuan a day, and if you calculate it for 250 working days a year, you can save 14,000 yuan in energy costs a year. If you use 5 years to calculate, you can save 70,000 yuan.
Because of its simple and flexible operation control, the electric forklift is much lighter than the internal combustion forklift. Its electric steering system, acceleration control system, hydraulic control system and brake system are all controlled by electrical signals, greatly reducing The labor intensity of the operator is very helpful for improving the efficiency of work and the accuracy of the work.
Maintenance cost: maintenance cycle, the maintenance cycle of electric forklift is two to three times longer than that of internal combustion forklift. Usually, the maintenance cycle of internal combustion forklift is up to 500 working hours, and many electric forklifts can reach more than 1000 hours. Maintenance cycle. Maintenance and maintenance, electric forklift maintenance is much easier than internal combustion forklift maintenance, usually only need to lubricate some joint activities such as gantry bearings, steering axle and other major inspection and cleaning, up to every 2000 or 3000 hours To replace the hydraulic oil, gear oil and hydraulic filter, the other materials are very limited. In addition to the lubrication of the internal combustion forklift, the engine oil and oil filter should be replaced every 500 hours (usually every 300 hours). The hydraulic oil, oil, transmission oil and these oil filters should be replaced every 1000 hours. Device. Also replace the belt (engine timing belt, generator belt, etc.). If the three-ton forklift is still used as an example, the maintenance cost of the internal combustion forklift should be 3,000-4,000 yuan (material cost only), and the maintenance cost of the electric forklift is only 1,000-1,500 yuan (material cost). .
The time required for maintenance, because the maintenance interval of the electric forklift is much longer than that of the internal combustion forklift, and the time required for each maintenance is much less than that of the internal combustion forklift, which greatly saves the labor cost required for maintenance. What is more substantial is that the downtime of the forklift is greatly shortened, so that the economic benefits brought by the improved efficiency of the forklift are difficult to calculate.
The service life of the battery of the electric forklift truck is 1500 charge and discharge cycles, which translates into a working hour of about 10,000 hours for the forklift truck. This is also equivalent to the engine overhaul of an internal combustion forklift. In this case, the battery of the electric forklift is replaced. The cost is close to the cost of overhauling the engine, but the speed of replacing the battery is much faster than the speed of overhauling the engine (or the speed of replacing the engine), and it also shows the advantage of time efficiency.
It can be seen that although we are purchasing electric forklifts for 30% more than internal combustion forklifts of the same load capacity, the total cost of use can be directly measured by data. The total cost of using an electric forklift truck is much lower than that of an internal combustion forklift. On the one hand, more and more forklifts operate indoors, so that the requirements for vehicle exhaust emissions are getting higher and higher. In Europe and the United States, strict regulations have been imposed, and internal combustion forklifts are prohibited indoors. Even though the laws and regulations in China have not yet strictly restricted the use of internal combustion forklifts indoors, the advantages of low noise and no exhaust emissions of electric vehicles have been recognized by many users compared with internal combustion forklifts. In addition, there are some technical reasons for choosing an electric forklift. The rapid development of electronic control technology makes the operation of electric forklifts more and more comfortable, the wider the scope of application, the more and more solutions to logistics, such as electric pallet trucks, electric stackers, reach trucks, three-way narrow Channel forklifts and the like are not possible with internal combustion forklifts, but electric forklifts solve these problems, especially in warehousing logistics system solutions. In terms of these aspects, the market demand for electric forklifts will grow faster and faster, and the market share of electric forklifts will also increase.
3. Electric forklifts are becoming more and more practical. The electric forklifts are driven by the vehicle power supply and driven by the motor to meet the requirements of road traffic and safety regulations. The advantage of the electric forklift is that it does not emit harmful gases that pollute the atmosphere. Even if it is converted into power plant emissions according to the electricity consumption, other pollutants are also significantly reduced in addition to sulfur and particulates, since most of the power plants are built away from dense population. The city is less harmful to humans, and the power plant is stationary, centralized discharge, easy to remove all kinds of harmful emissions, and related technologies. Since electricity can be obtained from a variety of primary sources, such as coal, nuclear power, and water power, people are worried about the depletion of oil resources. Electric forklift trucks can also make full use of the extra power charging during the evening power grid, so that power generation equipment can be fully utilized day and night, greatly improving its economic benefits. Some studies have shown that the same crude oil is refined and sent to the power plant for power generation. After being charged into the battery and then driven by the battery, the energy utilization efficiency is higher than that after being refined into gasoline and then driven by the gasoline engine, thus saving energy. And to reduce the displacement of carbon dioxide, it is these advantages that make the research and application of electric forklifts a hot spot in the forklift industry.
The difficulty of the electric forklift is that the current storage capacity of the battery is too small, and because the battery of the electric forklift is relatively expensive, and the economic scale is not formed, the purchase price is relatively expensive.
