On every corner of the world, cranes facilitate the heavy work that takes place daily at job sites, making them extremely versatile machines in which it would be virtually impossible to carry out all types of construction projects.

Another less pleasant fact about cranes is the one associated with accidents. Every year, at least forty-four people die in America due to accidents that occur while managing these machines according to the U.S. Bureau of Labor Statistics. Among the most common accidents are the ones related to contact with power lines, faulty maintenance, and dropped loads. The most unfortunate part of this problem is that 90% of them are caused by human error.

While many measures can be taken to prevent these casualties, it is significant to highlight the importance of crane load chart reading and interpretation. An undeniably fundamental part of the operation of cranes lies in the correct application of the directions explained in manuals and load charts.

Crane load charts

A crane load chart basically helps the operators in charge of a crane to calculate how much weight it can lift. Thanks to the chart, it can be ensured the lifting capacity is not exceeded when cranes are in operation.

Since cranes come from different manufacturers, their load charts will differ from one another. Sometimes the differences might look subtle especially because all load charts have the same basic information, but it is crucial to understand that each one of them is unique nonetheless.

It takes some time to understand the configurations provided by load charts; however, there are a few general factors that serve as guidance to comprehend their mechanics.

General factors that serve as guidance to comprehend the load chart

• Lifting capacity, which indicates how much load a crane can lift.
• Boom angle, which contributes to the stability of a crane to avoid losing balance when lifting a weight.
• Lift range, which provides the length of the boom needed along with the lift distance and weight. 

All these elements, and some others, are given by the load chart. A crane operator must know how to read and interpret the indications illustrated in load charts. Consequently, one of the most critical steps to prevent disastrous outcomes on the work site is to have qualified personnel able to perform their tasks in an extraordinary way.
