With this, an operator can figure out the angle the boom needs to be at to make sure they are positioned directly over the load. The use of a crane load chart makes this easier. If the load is being lifted from a point that is higher than ground level, knowing this height is also necessary. This rule isn’t always applicable to excavators.īefore making a lift safely, the operator needs to know the load’s weight and how far the load is from the boom’s turntable. While the basic concepts are similar, there are some essential differences.įor example, the closer a crane is located to the load, and the higher the boom angle is, the more lifting capacity the crane has. Load Charts Ensure Proper Use and Safe OperationĬrane load charts are unique from the backhoe and excavator load charts. This is necessary for each crane type the operator is using. To pass the certification, operators must demonstrate their ability to use modern load charts. Understanding the Crane Load Chart is Mandated by OSHAĪccording to the OSHA Crane Standard – subpart N mandates that all crane operators be certified. With this knowledge, they can safely operate any crane while ensuring the safety of others on the worksite.
