Introduction
As a forklift operator, knowing your forklift’s capability is critical. A forklift’s capacity is not simply the weight it can lift. In fact, a forklift’s weight capacity is not even constant. There are several parameters that you have to consider before loading a forklift. These parameters are written in the load capacity chart. If any of the parameters are exceeded, it can cause accidents like overturning, falling load, and pedestrian collision. In the following actions, we will learn about how to understand the parameters in a load capacity chart. Knowing the load capacity chart will help you to avoid those accidents.
Forklift data tagTo understand forklift load capacity, you must understand the forklift data tag. A forklift data tag or data plate is a metal plate or sticker that contains important information about the forklift, including the load capacity chart. Usually, you will find it in a very accessible place, such as near the instrument panel, on the side of the forklift, or the back.
Data tags are OSHA requirements and must be visible on all working forklifts. It should contain information tested by an approved testing laboratory. If you want to make modifications that change the parameters on the tag, you will need written approval from the manufacturer.
Usually, all the parameters are mentioned in metric and imperial (British) units. Your forklift's rated capacity parameters are given in a table within this data tag. Understanding load parametersIn the load capacity chart, there are three parameters:
Load Capacity: Load Capacity is simply the weight your forklift can lift. However, it does not stay the same. Depending on the other two parameters, load capacity changes. Lift Height: Lift Height is the height up to which your forklift can lift the rated weight. With increasing height, the forklift becomes more unstable.
Load Center: The Load Center is the measurement of the balancing point of the load. Load Center can be horizontal, vertical, or lateral. The Horizontal Load Center is the distance between the load center and the fork surface. Similarly, Vertical Load Center is the distance between the load center and the load backrest. The Lateral Load Center is the distance between the fork and load centers. When the load center increases, the balancing point moves far from the fork surface or the load backrest, making it less stable. How to read forklift load capacity chart
Let’s consider this forklift data plate:
The load capacity chart shows values in both metric and British units, and you can choose any one of them. According to the chart, this particular Toyota forklift can lift 10000 lbs at a maximum lift height of 147.5 inches when the load center is 24 inches. However, if you want to carry a bigger object with a load center of 30 inches, the maximum weight capacity decreases to 8850 lbs. Please note that the lateral load center always needs to be zero. In other words, a load should be properly balanced across the forks. An unbalanced load may cause the forklift to tip over to the left or right. The load capacity chart may vary across different makes, models, and types of forklifts.
For example, the above data tag is from a normal forklift with no provision for side shifting. An order-picker forklift will have a slightly different load capacity chart with data for side shifting allowance. In the following video, a different load capacity chart is explained in detail:
Our recommendationFor a forklift operator, knowing the load capacity chart is absolutely important. However, even after being careful, accidents do happen sometimes. We recommend equipping your forklift with proper safety attachments if an accident happens. In most cases of load imbalance, the forklift will overturn. In a rollover, a seatbelt can prevent the operator from being crushed under the forklift. Also, an external camera in the fork will help balance the weight during loading, which will avoid accidents.
