The load center distance is crucial in the specific application of forklifts because it directly impacts the stability and balance of the forklift. The load center distance is defined as the horizontal distance from the center of gravity of the load to the vertical face of the forks' front wall. This parameter is vital for determining the stability and balance of the forklift when handling goods.

In forklift design, the load center distance is a key parameter that helps designers ensure that goods can be balanced and stabilized correctly without exceeding the forklift's maximum lifting height. For instance, if a forklift's load center distance is 500mm, it means that the center of gravity of the goods should be located 500mm from the root of the fork to the vertical face of the fork's front wall to ensure that the goods do not cause instability or overturning by exceeding the specified load center distance.

Additionally, the load center distance is also related to other technical parameters of the forklift, such as its rated lifting capacity and maximum lifting height. These parameters collectively determine the performance and safety of the forklift. Therefore, in practical applications such as the design of electric forklifts, it is essential to ensure that all these parameters comply with national standards and industry best practices to guarantee operational safety and efficiency.

In summary, the importance of the load center distance in forklifts lies in its direct impact on the stability and balance of the forklift and how it interacts with other key technical parameters to ensure the forklift's performance and safety under various operating conditions.

Calculating the load center of a forklift mainly involves the following steps:

1. Determine the center of gravity of the load: Firstly, you need to know the position of the center of gravity of the load. This typically refers to the horizontal distance T from the center of gravity of the load to the vertical face of the forks' front wall when standard cargo is placed on the forks. This distance is measured in millimeters (mm).

2. Consider the weight of the forklift: When calculating the load center, you also need to consider the weight of the forklift itself to ensure safe operation.

3. Apply the calculation formula: The calculation formula for determining the load center of a forklift usually involves determining the horizontal distance from the face of the forks to the center of gravity of the load. Here is a more specific formula:

Load center distance = (Length of the load) * (Percentage of load center)

Notes:
(1) Length of the load: The length of the carried goods.
(2) Percentage of load center: The percentage of the manufacturer's specified load length used as the load center. Common percentages are 50%, 60%, or 70%.

How to accurately measure the center of gravity of the load?

To accurately measure the center of gravity of the load, several methods can be used:

1. Moment balance principle: This is the most basic and widely used method. By measuring the weight of the load at different positions and calculating the distance from these points to the overall center of gravity of the load, the position of the center of gravity can be determined using the moment balance principle. This method is suitable for goods of various shapes and sizes.

2. Three-point tilting force method: This method is particularly suitable for irregular or non-homogeneous goods. By applying forces at three different positions on the load and measuring their effects on the load, the position of the center of gravity of the load can be determined. This method can more accurately handle complex-shaped goods.

3. Static method: This is a simple and intuitive method that determines the balance of machinery or goods by measuring the position of the center of gravity when they are in different positions. It is usually possible to install gravity sensors or use devices such as spirit levels.

4. Digital technology: Using speckle image processing technology can improve the accuracy and sensitivity of center of gravity detection. This method calculates the coordinates of the center of gravity by analyzing the distribution of bright spots in the image and is suitable for situations requiring high precision.

5. Suspension method and traction method: These are more traditional manual methods that estimate the position of the center of gravity through physical operations. For example, suspending an object and drawing corresponding lines to estimate the position of the center of gravity through the intersection of these lines.

In conclusion, choosing the appropriate method depends on the type, shape, and required accuracy of the goods.

What are the differences in the standard load center distances of different types of forklifts?

There are certain differences in the standard load center distances of different types of forklifts. The following points can be observed:

1. For forklifts ranging from 1 ton to 4 tons, the specified load center distance is 500mm.

2. In specific forklift models, we can see different load center distances:
(1) The load center distance of LTMG diesel forklift FD30 is 500mm, FD200 is 900mm, and FD320 is 1220mm.
(2) The load center distance of LTMG 4-way Electric Reach Truck FRB20 is 500mm.
(3) For some other forklifts, such as the 12-ton side-loading forklift FDS120, the load center distance is 600mm.

From the above data, it can be seen that different types of forklifts consider their usage scenarios and operational requirements during design, hence the differences in load center distances. For instance, larger models of forklifts, such as FD320, have longer load center distances, which may be to accommodate larger loads and improve stability. On the other hand, smaller or medium-sized forklifts, such as the four-way forklift FRB20, typically have shorter load center distances to facilitate operation in narrow spaces.
