Electric forklift structural features and technical characteristics

 Electric forklift jacks is a DC power (battery) powered handling and transportation vehicles. According to foreign statistics, the Japanese electric forklift truck production has exceeded the total amount of 1/3. In Germany, Italy and some other Western European countries, the proportion of electric forklift reach about 50%. Electric forklift mainly due to the rapid development of the continuous progress of the manufacturers. Product appearance mostly with a streamlined design, modeling more beautiful. Major manufacturers realized the scale specialized production and spare parts production and assembly line operations. Precision, the degree of automation have increased. In the new materials, new technology, the most important manifestation of the transistor controller (SCR and MOS tube) applications. It appears that the use of electric forklift performance is greatly improved, generally speaking, electric forklift durability, reliability and applicability have been significantly improved, can compete with the internal combustion forklifts. This article comments on the market sales of larger four-wheel electric forklift balanced structural characteristics and development.
1, truck body is the main structure of the body, usually from the more than 5mm steel plate, which features a monocoque, body strength, can withstand overloads. On the forklift battery placement on the body, there are two different manufacturing techniques, namely the battery placed in or between the front and rear axles on the rear axle. Both technologies represent two Optimal truck design choice, and their advantages and disadvantages, good stability, but the car body of the available space is small, thus limiting the capacity of the battery, which does not exceed the carrying capacity of 3t forklift is not prominent, but for those sports complicated, 8h working hours, battery capacity demanding large-tonnage truck becomes serious.
Using a large capacity battery to extend the continuous electric forklift working hours, thereby expanding the use of electric forklifts, forklift manufacturer which is the common goal. The second case, when the battery is disposed in the rear axle truck, the truck's center of gravity improves, machine stability affected due to increase in the height of the truck, the driver's seat to improve, so the driver when operating a broader perspective, especially cargo handling large volume even apply. When the battery is placed in the rear axle, motor and hydraulic pump maintenance more convenient because the battery and take the pedals removed, the motor and pump it at a glance. At present, the domestic production of electric forklift, is the second most used technology, and foreign enterprises both.
2, the door frame at present, domestic electric forklift has been largely adopted wide view mast, lifting hydraulic cylinders are placed in the middle instead placed on both sides. Placement of hydraulic cylinders, there are two: one is the hydraulic cylinder located behind the door frame; another hydraulic cylinder is measured outside of the door frame. Mast is generally divided into standard, two or three type type. Domestic forklift lifting height is generally between 2 ~ 5m and 3m and 3m to the following of the majority, and foreign electric forklift lifting height is generally between 2 ~ 6m, because a high degree of three-dimensional warehouse, thus lifting height of 3m above, electric forklifts are much higher than domestic demand.
