However, passenger vehicles such as cars do not need or can not install power balls on the steering wheel. All power balls are added later. The decoration of power ball on car has more significance, less practical significance, and even affects driving safety. Because compared with the engineering vehicle, the rotation of the car is different. Friends who have driven cars, especially cars and engineering vehicles (agricultural vehicles), will have the following feelings: the steering wheel of cars is sensitive, it can be filled up in two and a half circles, the steering wheel can change the angle of the steering wheel with a slight displacement, and the vehicle direction will change accordingly. However, when driving engineering vehicles, it will be found that the steering wheel is relatively insensitive, and the number of full turns of steering wheel is much higher than that of cars. When the steering wheel is displaced, the steering wheel angle changes at a smaller angle. In fact, this is caused by the different rotation of the steering machine.

The operation or level problems of forklift drivers will inevitably result in the damage of guardrails, brackets and pallets. The damage is caused by scraping off plastic powder and hitting heavy shelves.How to select and configure the shelves and forkliftsA protective cover is added to the leg or guardrail, but the method can reduce the damage of forklift to the pallet and shelf, but the technical level provided to the driver is not high, which makes it difficult for the management personnel to judge the operation level of the driver.When planning the warehouse, the shelf manufacturer can be required to appropriately increase the width of the feeding shelf channel, and reserve a certain safety distance for the driver in advance to reduce the impact of forklift on the bracket.

In the traditional management of forklift fleet, there are some management difficulties that make people very headache, such as: the speed problem of forklift driving, the problem of over height and over weight of goods carried by forklift, the problem of forklift maintenance, the problem of forklift anti-collision, the problem of forklift leasing, data analysis and so on. If there are only a few trucks, it doesn't need to spend a lot of effort to manage, but a forklift fleet is basically composed of dozens, hundreds or even more forklifts. To achieve effective management, improve management efficiency and forklift utilization, it is necessary to manage forklifts with the help of forklift fleet management system.

Forklift plays a very important role in the logistics system of an enterprise, and it is the main force in the material handling equipment. At present, there are many forklift brands available in the market, with complex models. Each forklift has its typical operating conditions. Powered forklift trucks can generally be divided into three categories:Internal combustion forklift, electric forklift and storage forklift. Diesel, gasoline, liquefied petroleum gas or natural gas engines are generally used as power for ordinary internal-combustion forklift trucks, with a load capacity of 1.2-8.0 tons and a width of 3.5-5.0 meters. Considering the exhaust emission and noise problems, they are usually used outdoors, in workshops or other places without special requirements for exhaust emission and noise. Due to the convenience of fuel replenishment, it can realize long-term continuous operation, and it can be competent to work in harsh environment (such as rainy day).The electric forklift is powered by an electric motor and powered by a battery. The bearing capacity is 1.0-4.8 tons, and the width of operation channel is generally 3.5-5.0 meters. Because there is no pollution and low noise, it is widely used in the environment, such as medicine, food and other industries. Since each battery needs to be charged after about 8 hours of operation, it needs to be equipped with backup battery for multi shift working conditions.Storage forklift is mainly designed for goods handling in the warehouse. Except for a few warehouse forklifts (such as manual pallet forklifts), which are driven by manpower, others are all driven by electric motor. Because of its compact body, flexible movement, light weight and good environmental protection performance, they are widely used in the warehouse industry. In multi shift operation, the storage forklift driven by electric motor needs to have backup battery. In urban logistics distribution, a large number of manual light and small forklifts are also commonly used.The basic operation functions of forklift include horizontal handling, stacking / picking, loading / unloading and picking. According to the operation function that the enterprise wants to achieve, it can be preliminarily determined from the models described above. In addition, special operation functions will affect the specific configuration of forklift, such as carrying paper roll, molten iron, etc., which requires forklift installation accessories to complete special functions. In the application of forklift, there are certain requirements for pallet or cargo specification, lifting height, width of operation channel, climbing degree, etc., as well as requirements for operation efficiency (different models have different efficiency), operation habits (such as habitual driving or standing driving), etc. Warehouse environment has requirements on noise or exhaust emission and other environmental protection aspects. Generally, warehouse forklift is selected. In cold storage or explosion-proof environment, the configuration of forklift should also be cold storage or explosion-proof. The superior performance of high-quality forklift is often reflected in * * rate, low cost, high reliability, good ergonomic design and convenient service. **Rate does not only mean high speed (driving, lifting, lowering speed), it also means that the operator needs a short time to complete a working cycle, and can maintain this efficiency throughout the working time. Low cost refers to the total annual cost * * of purchasing and using forklift. The use cost of forklift includes: ① purchase cost; ② maintenance cost; ③ energy consumption cost; ④ labor cost;High safety, easy to operate, comfortable, easy to maintain is also an important indicator of forklift use. Enterprises need to purchase forklifts according to the requirements of economy and * * rate according to the operating environment of forklifts, the weight of handled items, operating frequency, storage mode and other factors.

With the development of science and technology, electric vehicle becomes a new means of transportation, and electric forklift will replace the traditional forklift with its advantages of energy conservation, environmental protection, high-speed intelligence, and become the main force of industrial development.From January to March, the output of electric forklift reached 7757 in Zhejiang Province, followed by 5437 in Shandong Province. In the figure, the cumulative output of other regions from January to march is relatively close, but the output of Anhui province increased by * more than the same period of last year, reaching 20.27%. On the whole, the growth trend of these regions is not very big, relatively stable, and generally increasing. At the same time, the production of electric forklifts in China has also been significantly improved: in March 2014, the production of electric forklifts in China was 18516, the same as that of Anhui Province It is 13.78% higher than the previous year, and the cumulative output from January to march is 36547 units, with a cumulative year-on-year growth of 2.24%The steady growth of electric forklift production from January to March 2014 fully shows that the electric forklift industry in China is moving forward steadily, with large market demand and broad development prospects. However, due to the late start of the industry, there is still a certain gap with developed countries such as Europe and the United States in the level of development. In the future, the industry needs to continue to strengthen the adjustment of industrial structure and the transformation and upgrading of technology, strengthen independent research and development, vigorously develop intelligent high-end electric forklifts, improve its market competitiveness, seize the international market share, and lead the industry to a higher level as the industry matures.
