A crane’s load chart is the most important resource a crane operator should know for ensuring crane safety, and for determining what a particular crane is capable of lifting at any given time. With all of the different crane manufacturers out there, it is imperative that the crane’s load chart be well understood.
A load chart of a crane specifies the crane’s capabilities, detailing its features and how its lift capacity varies when considering distance, angle and length.
Before a crane is rented, transported, employed or purchased, the crane chart must be consulted to determine the best crane suitable for the task at hand.
How to use the load chart of your crane to determine your crane load capacity
It is pertinent to note that only load charts that are found in the equipment operation manual or posted by the manufacturer in the equipment should be used. The load charts are specific to the make, model and configuration of a specific piece of equipment, therefore any load chart do not apply to any lifting equipment.
Don’t forget to include adjustments for buckets, boom extensions, load blocks, hoisting rope and other attachments that will alter the lifting capacity of the crane or equipment used to perform the lift. For example, the weights of hooks, blocks, buckets, slings and other handling devices must be added to the load or deducted from the equipment lift capacity.
