Introduction to the characteristics of Heli electric forklift
An electric balance forklift is a loading, unloading and handling vehicle powered by a DC power supply (battery). The rapid development of electric forklifts is mainly due to the continuous progress of electric forklift parts manufacturers. Generally speaking, the durability, reliability and applicability of electric forklifts have been significantly improved. The annual growth rate of electric forklifts is very fast, and it is expected to surpass internal combustion forklifts in about 10 years.
The following introduces the structural characteristics of the four-point electric balance forklift with the largest sales volume of Heli electric forklift:
1. The installation position of the battery of the electric forklift
The body of the forklift is the main structure of the forklift. It is generally made of steel plates above 5mm. It is characterized by no girders, high strength, and can withstand heavy loads. Regarding the placement of the battery on the forklift body, there are two different manufacturing techniques, that is, the battery is placed between the front and rear axles or on the rear axle.
Putting the battery pack on the front axle has good stability, but the available space in the car body is small, which limits the capacity of the battery. This is not prominent for forklifts with a load capacity of not more than 3t, but for those with complex movement conditions, 8h Large-tonnage forklifts with high battery capacity requirements during working hours have become serious. The use of large-capacity batteries to extend the continuous working time of electric forklifts, thereby expanding the scope of use of electric forklifts, is the common goal pursued by all forklift manufacturers.
In the second case, when the battery is arranged on the rear axle of the forklift, the center of gravity of the forklift is increased, and the stability of the whole machine is affected. As the height of the forklift increases, the driver's seat increases, so the driver has a wider vision during operation, especially It is more applicable when handling bulky goods. When the battery is placed on the rear axle, the maintenance of the motor and hydraulic pump is more convenient, because after removing the battery and pedal, the motor and hydraulic pump are clear at a glance.
At present, most of the electric forklifts produced by Chinese electric forklift companies such as Heli electric forklifts have forklift batteries arranged on the rear axle.
2. Mast of electric forklift
At present, most electric forklifts at home and abroad have adopted wide-view masts, and the lifting hydraulic cylinders have been placed in the middle instead of being placed on both sides. There are two positions for the hydraulic cylinder: one is the hydraulic cylinder behind the mast; the other is the hydraulic cylinder outside the mast. Masts are generally divided into standard type, two-section type or three-section type. The lifting height of domestic electric forklifts such as Heli electric forklifts, JAC electric forklifts, and Hangcha electric forklifts is generally between 2~5m, and most of them are 3m and below 3m. The lifting height of foreign electric forklifts is generally 2~ Between 6m.
3. The cab of an electric forklift
Since most electric forklifts are used for indoor transportation, there is generally no closed cab, and only a protective overhead guard is installed. The most advanced electric forklifts in the world are developed according to advanced ergonomics, and use comfortable hydraulic damping suspension seats, which can be adjusted according to the driver's height and weight. The dual-pedal acceleration system does not need to steer when the forklift changes the driving direction, and the inclination of the steering wheel column can be adjusted according to the driver's requirements. Therefore, these new designs greatly reduce the labor intensity of the driver.
4. Drive system of electric forklift
The drive system is one of the key components of electric forklifts. There are great differences in the structure of the drive system of various forklifts, and there are also differences in the layout of a single motor. Because it is driven by dual motors, it has good acceleration and climbing performance and large traction. The electronic full speed system is adopted to replace the original mechanical differential system, and the usability has been greatly improved.
5. Hydraulic system of electric forklift
Electric forklifts generally use a separate motor to drive a gear pump to provide hydraulic power for the lifting and tilting of its mast working system. At present, domestic forklifts do not realize the speed adjustment of the hydraulic motor. After the hydraulic motor is started, it can only rotate at a high speed. It will not automatically adjust with the change of function and pressure. The excess flow can only flow back to the tank through the overflow valve. Cause a waste of energy.
6. Braking system of electric forklift
General electric forklifts mainly use mechanical parking brakes and hydraulic service brakes. Hand brake is used for parking and foot brake for driving.
7. Electric control and self-diagnosis and LCD display system of electric forklift
Electrical control is an important factor showing the technical level of electric forklifts. Therefore, with the development of electronic technology, the electronic control of battery forklifts is becoming more and more perfect. Leadingforkliftparts is supplying electric forklift parts, such as electric forklift battery pack and axle parts and brake parts. We have been focusing on forklift parts for 22 years.
