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. How to identify quadrants of operation from load chart dataĪ crane load chart is a vital tool that managers and operators need to understand fully.How to identify structural and stability values in load capacity charts.How to determine gross and net capacities.In this article you will be able to learn the following : In addition to safety, there are several other reasons you need to know how to read and use the crane load chart. If this is the case, it may not be safe to lift the pipe from the truck and place it in or next to the trench. One example of this is if you have a truck full of pipe located too far from the crane being used.

Factors That Reduce Load Capacities Production Operations.Load Charts Ensure Proper Use and Safe Operation.Understanding the Crane Load Chart is Mandated by OSHA.Are roads and entrances able to accommodate?Īll these factors are essential to the process of selecting a crane for a safe and successful job. Establish how the crane will access and leave the site.Ensure whether the ground can support the crane.Consider what boom length will be required.Discern whether specialized rigging equipment will be needed to avoid removing critical plant equipment during the lift.Verify if the crane will need to work around obstructions during set up.Determine if obstructions will impede the counterweight when swinging.Allow for the distance from jib head to the hook.Consider the hook height required with lifting equipment.Allow for the height of obstructions between crane and load.Determine clearance issues, either height under ceiling or overhead obstructions.If not known, consider consulting an engineering professional. Calculate the maximum radius from the center of pin.Should it be a heavy lift crane? Boom truck crane? Rough Terrain crane? Weight and size of load, location, reach, obstructions, and other factors must be determined before choosing crane. To properly size and select a crane for a job many factors must be considered to determine the right type of crane and corresponding capacity.
