What is a Crane Load Chart?
A crane load chart is a graphical representation of the maximum weight that a crane can lift at various boom lengths and boom angles. It is an essential tool for crane operators to determine the safe working load for different lifting configurations.
The load chart typically consists of a series of tables and graphs that provide information about the crane’s lifting capacity. It includes data such as the boom length, boom angle, and the corresponding maximum lifting capacity. The chart may also include information about the crane’s counterweight, which affects its lifting capacity.
The load chart is crucial for ensuring safe and efficient crane operations. By consulting the load chart, crane operators can determine the maximum weight they can lift without exceeding the crane’s capacity. This helps prevent accidents and equipment damage due to overloading.
Cranes come in different types and sizes, and each has its own load chart. The load chart is specific to the crane model and must be provided by the manufacturer. It is important for crane operators to be familiar with the load chart of the crane they are operating and to use it as a reference when planning and executing lifts.
Overall, a crane load chart is an indispensable tool for crane operators. It allows them to make informed decisions about load handling and ensure the safety of operations. By following the load chart guidelines, operators can maximize the crane’s lifting capacity while minimizing the risk of accidents.
The Importance of Crane Load Chart Practice
Crane load chart practice is essential for anyone operating or working with cranes.

Regular practice with load charts ensures that crane operators are well-equipped to handle lifting operations effectively and safely.
How to Read a Crane Load Chart
Reading a crane load chart is an essential skill for crane operators and anyone involved in lifting operations. A load chart provides crucial information about the crane’s lifting capacity, allowing operators to determine the maximum weight that can be safely lifted at different boom lengths and angles.
Here are the key steps to effectively read a crane load chart:
1. Understand the Terminology
Before diving into the load chart, it’s important to familiarize yourself with the terminology used. Some key terms include:
- Capacity: This refers to the crane’s maximum lifting capacity, usually measured in tons.
- Boom Length: The length of the crane’s boom, which can be adjusted to reach different heights.
- Boom Angle: The angle at which the boom is extended, affecting the crane’s lifting capacity.
- Radius: The horizontal distance between the crane’s center of rotation and the center of the load being lifted.
2. Locate the Load Chart
The load chart is typically located near the operator’s cabin or in the crane’s manual. It is important to have easy access to this chart before starting any lifting operation.
3. Determine the Boom Length and Angle
Once you know the boom length and angle required for your lifting operation, locate these values on the load chart. The chart will usually have a series of rows and columns with different boom lengths and angles.
4. Find the Lifting Capacity
To find the lifting capacity at a specific boom length and angle, locate the corresponding cell on the load chart. This cell will display the maximum weight that the crane can safely lift at that configuration.
5. Consider Other Factors
While the load chart provides valuable information, it is important to consider other factors that may affect the crane’s lifting capacity, such as the radius, wind speed, ground conditions, and the presence of any obstacles. These additional factors should be taken into account to ensure safe and successful lifting operations.
By following these steps and carefully reading the crane load chart, operators can confidently determine the crane’s lifting capacity and execute lifting operations safely and efficiently.
Common Types of Crane Load Charts
A crane load chart is a graphical representation of a crane’s safe lifting capacity at various radii and boom angles. It is an essential tool for crane operators to determine the maximum weight that can be safely lifted and the ideal boom length and angle for a specific lift. There are several types of crane load charts that are commonly used in the industry:
1. Static Load Chart
The static load chart provides the maximum lifting capacity of a crane at various boom lengths and radii. It takes into account the crane’s stability and the maximum allowable stresses on the crane’s structure. Operators refer to the static load chart to determine the maximum weight that can be safely lifted under normal operating conditions.
2. Dynamic Load Chart
The dynamic load chart is used to determine the crane’s lifting capacity when performing dynamic lifts, such as lifting a load that is moving or subjected to external forces. It considers the crane’s ability to handle sudden changes in load and movement, providing operators with a more accurate lifting capacity for dynamic lifting situations.
3. Load Moment Indicator (LMI) Chart
The Load Moment Indicator (LMI) is a device installed on cranes that displays the crane’s safe lifting capacity in real-time. The LMI chart is typically displayed on the crane’s control panel and provides operators with continuous feedback on the crane’s current lifting capacity. It takes into account factors such as boom length, angle, load radius, and wind conditions to provide accurate and up-to-date information.
4. Outrigger Load Chart
The outrigger load chart is specific to cranes equipped with outriggers, which are used to provide extra stability during lifting operations. This chart indicates the maximum allowable load based on the crane’s outrigger configuration, including the number of outriggers deployed and their extension length. Operators refer to this chart to ensure that the crane is set up correctly and operating within safe limits.
In conclusion, crane load charts are vital tools for crane operators to ensure safe and efficient lifting operations. By understanding and interpreting these charts accurately, operators can make informed decisions about the maximum safe lifting capacity of the crane, reduce the risk of accidents, and ensure the successful completion of lifting tasks.
