How to read a forklift load capacity chart
Find the load centre, match the lift height and check the permitted load step by step.
Read the labels before the numbers
A load capacity chart links the load and lifting conditions to the permitted capacity. Before looking for a number, read the title, labels and units. Identify the lift height and the distance to the load centre. Similar information may appear in a table or graph. Do not automatically use the layout of the previous question, even when two diagrams look similar. The labels tell you how this particular diagram works.
Extract only the information actually given in the question. Separate mass, length and height. Do not add conditions that are absent from the text or picture. Open a small image at full size. A misread unit can change your answer even when you understand the method.
Find the length along the forks
In a typical exercise with a uniformly distributed load, the load centre distance is half the load length measured along the forks. The direction matters. The width you see from the front may be a different measurement. First picture how the load sits on the forks, then identify the length in that direction. Only after that should you find the distance needed for the chart.
For example, a uniform load one metre long along the forks gives a half-metre distance for this exercise. This illustrates the reasoning, rather than providing a value for every load. If the mass is distributed differently, do not assume the same relationship without checking. Real work requires information about the actual load and equipment.
Match distance and lift height
Find the lift height stated in the question. Read the permitted capacity for both that height and the identified load centre distance. The biggest number anywhere on the chart is not automatically the answer. In a table, the value may sit where a row and column meet. In a graph, you must select the appropriate curve or area and check the labels carefully.
Imagine two questions with the same load but different lifting heights. Read the correct chart position again for each question. Do not carry the first result into the second from memory. If an exact parameter is missing, do not invent an intermediate value. In study, review the explanation. At work, consult the equipment documentation and clarify the uncertainty with the responsible person.
Check and practise the full sequence
Compare the stated load mass with the permitted value you read. Check the units, height and distance again. Explain in one sentence where the result came from. If you cannot point to that place on the chart, return to the labels before selecting an answer. Remembering a letter or the colour of a box does not teach you to interpret a new diagram.
Practise different illustrations using the same sequence: question data, direction of length, load centre, lift height, matching value and comparison. When you make a mistake, note the missed step. Return later without checking your earlier answer. Bank illustrations help you practise the reading method. They do not replace the instructions and capacity plate for the actual forklift you will use.
