Electric forklift technical characteristics and purchase points

[DIG-DOG]

Electric forkliftis a loading, unloading and handling vehicle powered by DC power supply (battery). According to foreign statistics, the output of electric forkliftin Japan has exceeded 1/3 of the total number of internal combustion forklift. In some Western European countries such as Germany and Italy, the proportion of electric forklifts reaches about 50%.

The rapid development of electric forkliftis mainly due to the continuous progress of various manufacturers. Most of the product shape adopts streamlined design, and the shape is more beautiful. The main manufacturers have realized large-scale production and specialized production of parts and assembly lines.

Machining accuracy and automation have been improved. In terms of new materials and new processes, an important embodiment is the application of transistor controllers (SCR and MOS tubes). Its emergence has greatly improved the performance of electric forklift, in general, the durability, reliability and applicability of electric forklifthave been significantly improved, and it can compete with internal combustion forklifts. This paper mainly reviews the structural characteristics and development of four fulcrum electric balanced forklift trucks with large sales volume in the market.

1, the car body is the main structure of the forklift truck, generally made of more than 5mm steel plate, which is characterized by no girder, high strength of the car body, can withstand heavy loads. There are two different manufacturing techniques in terms of the placement of the battery on the forkliftbody, that is, the battery is placed between the front and rear axle or above the rear axle. These two technologies represent the two choices of forkliftdesign, and each has advantages and disadvantages, good stability, but the available space in the body of the car is small, so it limits the capacity of the battery, which is not prominent for the forkliftwith a load of no more than 3t, but for those who have complex movements and large tonnage forkliftwith high battery capacity requirements during 8h working hours, it becomes serious.

2, the use of large-capacity batteries to extend the continuous working time of electric forklift, so as to expand the scope of use of electric forklifts, which is the common pursuit of forklift manufacturers. In the second case, when the battery is arranged on the rear axle of the forklifttruck, the center of gravity of the forklift truck is increased, the stability of the whole machine is affected, because the height of the forklifttruck is increased, the driver's seat is improved, and the driver has a wider vision during operation, especially when handling large goods, it is more suitable. When the battery is placed on the rear axle, the maintenance of the motor and hydraulic pump is more convenient, because the motor and hydraulic pump are immediately visible after the battery and pedal are removed. At present, most of the electric forklifts produced by domestic enterprises use the second technology, while foreign enterprises have both cases.

3, door frame At present, most of the electric forkliftat home and abroad have adopted a wide vision door frame, and the lifting hydraulic cylinder is placed on both sides from the middle. There are two positions for the hydraulic cylinder: one is that the hydraulic cylinder is located behind the door frame; The other is that the hydraulic cylinder is located outside the door frame. The gantry is generally divided into standard type, two-section type or three-section type. The lifting height of domestic forklifts is generally between 2-5m, and the majority of them are 3m and below, while the lifting height of foreign electric forklifts is generally between 2-6m, due to the high degree of three-dimensional warehouse, so the lifting height of 3m or more, the demand for electric forkliftis much higher than that of domestic forklifts.

Electric forkliftpurchase points

In the general description of electric forklifttruck, although the choice of forklift truck model and configuration is introduced, due to different use environments, different workloads, the size of the volume of the transported goods, the height of the goods, the size of the channel, the load size and other factors are variable, determining the selection of electric forklift truck is a complex and comprehensive work, it is understood that some users due to improper selection, The device cannot be put into use, resulting in idle equipment waste. So how to choose a relatively matching forklift truck? The following is a supplement to the selection of electric forklift trucks:

1, pay attention to the working environment: electric stacker, electric truck on the ground requirements, must be hard ground use, the ground flatness can not be too big, if the ground is grease, paint the ground, choose forklifttruck must buy non-slip type stacker.

2, pay attention to the workload: different workload to choose a relatively matched battery, the user must be explained when ordering, production can be selected according to the user's workload matched battery.

3, pay attention to the volume of the goods: the size of the transported goods is related to the load center of the fork, the length of the fork is related to the carrying capacity of the forklift, and the choice of the relative fork and forkliftis particularly important.

4, pay attention to the lifting height of the goods: according to the height of the transported goods, the selection of forkliftgenerally refers to 1.6 meters, every rise of 200mm, the load weight drops 50kg, so as to calculate.

5, pay attention to the size of the channel: the size of the channel is related to the transformation radius of the electric forklift, and it must be explained when purchasing the forklift.

6, how to choose a relatively matching forklift: single-sided pallet, double-sided pallet, with or without a fixed leg forklift, the length of the slope, the degree of the slope, the length of the forklift truck requirements, the tonnage of the loaded and unloaded goods to the top weight, the transported goods such as sideways, forward, backward, etc.
