What are the main classifications of electric forklifts?

by:Staxx     2021-05-31
Electric forklifts refer to forklifts that use electricity to work, and most of them work for batteries. In the early stage of the development of electric forklifts, lead-acid batteries were the mainstay. With the development of industrial technology, lithium batteries are gradually being applied to electric forklifts. The lifting range of electric forklifts is 1-10 tons. And compared with internal combustion forklifts, the advantages of low noise and no exhaust emissions of electric vehicles have also been recognized by many users. In addition, there are some technical reasons for choosing electric forklifts. The rapid development of electronic control technology makes the operation of electric forklifts more and more comfortable, the wider the scope of application, and the more and more solutions to logistics. From these aspects, the market demand for electric forklifts will definitely grow faster and faster, and the market share of electric forklifts will also become larger and larger. Electric forklifts are driven by electricity. Compared with internal combustion forklifts, electric forklifts have the advantages of no pollution, easy operation, energy saving and high efficiency. With the development of economy and the improvement of environmental protection and energy saving requirements, electric forklifts are developing rapidly. Market sales are increasing year by year. It should be noted that lead-acid batteries should not be placed horizontally! Because the inside of the battery is generally 22-28% dilute sulfuric acid. When the battery is being placed, the electrolyte can flood the electrode plates and there is still a little space left. If the battery is placed horizontally, part of the electrode plates will be exposed to the air, which is very detrimental to the battery plate, and the observation hole of the general battery or There are vents on the top of the battery to communicate with the outside, so the battery's lateral discharge solution can easily flow out. Lead-acid battery classification Electric forklifts can be divided into: four-way electric forklifts, electric tractors, three-point electric forklifts, four-point counterbalanced forklifts, three-point mini forklifts, special electric forklifts for cold storage, electric explosion-proof forklifts, walking counterbalanced forklifts, three Pivot inserting leg stacker, station crane, four fulcrum inserting leg stacker, four fulcrum wide leg stacker, electric tractor, picking truck and other electric series material handling equipment. Principle The battery forklift uses the battery as the source of power to drive the driving motor and the hydraulic system motor to realize driving and loading and unloading operations. An electric pallet truck is a loading, unloading and handling vehicle powered by a DC power supply (battery). In terms of new materials and new processes, an important manifestation is the application of transistor controllers (SCR and MOS tubes). Controllers are becoming more and more intelligent with the growth of technology. Its appearance has greatly improved the performance of electric forklifts. Generally speaking, the durability, reliability and applicability of electric forklifts have been significantly improved, and they can completely compete with internal combustion engine forklifts. Daily operating procedures 1. Maintain a proper starting speed when starting, and should not be too violent. 2. Pay attention to the voltage of the voltmeter. If it is lower than the limit voltage, the forklift should stop running immediately. 3. When the forklift is moving, it is not allowed to flip the direction switch to change the direction of travel to prevent burning of electrical components and damage to the gears. 4. Driving and lifting should not be carried out at the same time. 5. Pay attention to whether the sound of the driving system and steering system is normal. If abnormal sound is found, troubleshoot the fault in time. It is strictly forbidden to work with illness. 6. Slow down in advance when changing. 7. When working on poor road conditions, its importance should be appropriately reduced, and the driving speed should be reduced. Note 1. The weight of the goods must be known before lifting, and the weight of the goods must not exceed the rated lifting capacity of the forklift. 2. When lifting and packaging goods, pay attention to whether the goods are tightly wrapped. 3. Adjust the spacing of the forks according to the size of the goods, so that the goods are evenly distributed between the two forks to avoid partial load. 4. The mast should be tilted forward when the goods are inserted into the stack. After the goods are loaded into the fork, the mast should be tilted backwards so that the goods are close to the fork wall, and the goods should be lowered as much as possible before driving. 5. When lifting goods, they should generally be carried out in a vertical position. 6. During manual loading and unloading, the hand brake must be used to stabilize the fork. 7. Simultaneous operation of walking and lifting is not allowed. 8. When carrying goods on a steeply sloped road, if something falls in accidentally when adding electrolyte, do not use metal to fish, use wooden rods to pick out impurities; if iron or copper wire is used to fish, metal molecules will Under the corrosion of sulfuric acid, it enters the battery to form self-discharge and damage the battery. If the vehicle is stopped for more than 20 days, the negative wire of the battery should be removed to avoid leakage accidents!
