Electric trucks have become the market-oriented storage equipment. Now, in the storage equipment, the original market pattern is quietly changing. The original handling equipment, mainly manual trucks and internal-combustion forklifts, is widely used in the market. But now, with the continuous development and progress of science and technology, there is a kind of energy-saving, environmental protection, low noise, pollution-free, stable and fast market The electric transporter has greatly impacted the original market pattern. In addition, in recent years, the manual carrier is facing the fierce competition of the same industry and the further narrowing of market profits. The cost of after-sales service is gradually increasing, and manufacturers are under more and more pressure.In the face of the fact that the internal-combustion forklift truck still maintains a certain market share in the market and the market sales increase slightly, the development of internal-combustion forklift truck will be saturated in the future from the perspective of the whole trend. Although the internal-combustion forklift truck has strong power and strong mobility, it can work continuously in a complex environment, but it is noisy and emits pollution gas, and the market competition is also increasing, and the market profit is increasing Gradually shrink, only a few powerful manufacturers can maintain certain advantages.However, the emergence of electric trucks has brought great impact on the two kinds of forklift trucks, which eventually led to changes in the market pattern.Electric carrier is developed gradually according to the changing market demand and the continuous progress of technology. In the face of increasingly serious environmental problems and the concept of energy conservation and environmental protection, the R & D and manufacturing of electric carrier has emerged, greatly leveraging the entire market of moving materials! According to the relevant data, in developed economies such as Europe, the United States and Japan, electric trucks are gradually replacing internal-combustion forklifts in relevant industries, and the market share is gradually increasing. However, in developing countries, this development trend is also gradually formed. It is inevitable that electric trucks will become the leading equipment in the future market.The electric carrier mainly relies on the battery as the power, DC motor drive, hydraulic power unit lifting, centralized control of the control handle, convenient operation, stable, fast, suitable for heavy load and long-term cargo transfer and loading, compared with the manual carrier, it greatly improves the cargo handling efficiency and reduces the labor intensity, but the price is relatively high. In some warehouses and distribution centers, because there are certain requirements for indoor cargo handling environment, the selection of electric trucks for cargo handling and no impact on efficiency can meet the relevant environmental requirements. Compared with the internal combustion forklift, the price is equivalent, which is * * in the handling equipment!

The transporter is the storage and logistics equipment for carrying goods. Now as a new type of electric logistics equipment, the all electric transporter has a place in the vast market. It is reported that with the increasing number of enterprises using electric vehicles in the market, people are increasingly worried about the failure of electric vehicles in the use process, so effectively avoiding or removing the hidden trouble has become the concern of the enterprise owners. In this regard, the small edition collected and summarized some problems that are easy to occur in the application process of electric carriers and how to solve these problems.Troubleshooting:1、 Shivering as you ascend1. There is air in the lifting cylinder, which can be solved by multiple loading and lifting methods,2.

At present, there are 2 forklift production units and 349 forklift use units in Ninghai County, Zhejiang Province. The MIS system of Ningbo special equipment comprehensive management shows that the total number of registered forklifts is 590, of which 566 are in use. The results of daily inspection and special inspection of forklift safety show that different forklift users have different characteristics in the process of using forklift, and there are certain problems, while the problems also show a variety of characteristics. From the specific details, the quality and safety problems in the use process are mainly reflected in two aspects:First, there are general problems in the use of forklift. Some users have not signed the letter of commitment for safe use of forklift, the main responsibility for safety has not been well implemented, and the "three two one one" safety management system is not sound or effectively implemented. The forklift operators drive without license, the forklift fails to be inspected after the expiration of the time limit, and the forklift is still in use even if it fails to pass the inspection.Second, there are some special problems in the use of forklift. Forklifts are special equipment only when they are working in the field (factory), and they are not special equipment when they are working out of the field (factory). Moreover, as a kind of special equipment, forklift is different from general special equipment. It has strong mobility, and can be operated in different fields (factories). Some forklifts are sold many times and rented temporarily, so random data can not be found. However, some used forklift equipment has some faults, which can barely pass the inspection after maintenance. Once there are undocumented operators to operate it, the so-called safety risk prevention and control system will be in vain, the safety supervision measures cannot be implemented in time and effectively, and the accident rate and the probability of injury and death will increase.In recent years, forklift accidents are high and the situation of safety production is severe. In order to effectively reduce safety risks and give full play to innovative practices, it is necessary to focus on the following work:First, strengthen the "one-stop" supervision of forklift safety. "One-stop" supervision refers to all-round and full process supervision from forklift design, manufacturing, operation, use, transformation, maintenance, inspection to scrapping, etc., which is required to be linked to achieve closed-loop management. Further study and adjust the forklift management methods, further standardize the forklift and its driver management, strengthen the supervision of forklift business units, and carry out the supervision and inspection of forklift maintenance and repair. For different degrees of illegal acts, serious punishment shall be made in accordance with the provisions of laws and regulations. If the circumstances are serious, they shall be transferred to the public security and judicial organs for handling, and they shall not be tolerated.Second, accelerate the transformation of forklift safety supervision mode. The forklift for mobile operation is similar to the motor vehicle to some extent. In order to avoid the supervision responsibility effectively, we should realize the transformation from "nanny" supervision mode to "police" supervision mode as soon as possible. On the one hand, we can learn from some good practices and measures of traffic police department in motor vehicle supervision to effectively implement the main responsibility of forklift users; on the other hand, we suggest that the higher level government should implement the safety supervision responsibility of special equipment in towns (streets) as soon as possible, increase the training of township quality supervisors, and require the towns (streets) to focus on the filing of special equipment in enterprises Do a good job of forklift archives, and achieve the goal of special plane driving and special file management.

In the state of no one to operate, a carrier can easily complete a series of "heavy manual work" such as loading, transportation, unloading, etc.On the afternoon of September 26, the unmanned carrier developed by Professor Huang Yumei, vice president of Xi'an University of science and technology and head of National Key Laboratory, demonstrated on the spot at the "intelligent innovation Salon of mechanical equipment" activity held in Keqiao science and technology innovation building, attracting many participants to stop and watch.It is understood that the "intelligent innovation Salon of mechanical equipment" is mainly aimed at the textile equipment manufacturing enterprises. However, the reporter saw at the scene that many heads of textile printing and dyeing enterprises such as Huadong printing and dyeing Co., Ltd. and Meisheng Industrial Co., Ltd. also came."Mainly come to the market." Wang Xudong, head of East China printing and dyeing Co., Ltd. from Binhai Industrial Zone, told reporters that when enterprises purchase equipment, they will consider more intelligent equipment, which can not only improve production, but also reduce labor. It is understood that the enterprise has 18 porters, and the labor cost is 900000 yuan based on 50000 yuan annual salary. And because of the labor intensity of porters, they are often difficult positions for enterprises to recruit. "If this driverless truck can be used in the printing and dyeing workshop, our enterprise will not have to worry about the lack of porters." Wang said.Printing and dyeing enterprises have a daily circulation of 10 tons of grey cloth, but the actual transportation volume is more than 40 or 50 tons. Why does the carrying capacity of goods double? "Logistics information docking is not smooth, there is unnecessary return to transport." A printing and dyeing business operator said."The high intelligent unmanned handling vehicle can not only replace the labor force completely, but also connect every program seamlessly to improve the work efficiency." Professor Huang Yumei pointed out that intelligent and automatic equipment will become the development direction of advanced manufacturing equipment and application in the future. According to reports, the intelligent self-control 2-DOF unmanned carrier developed by Professor Huang Yumei's team will be used in the workshops of red, green and blue printing and dyeing enterprises at the end of the year.
