CRANE LIFT HOW TO

Safety is a team effort that requires both the operator and management working with the same safety objectives. Knowing what to look for is a good start to a safer job site. Load charts may have become more complex, but the key information provided has not changed significantly. And, donвЂ™t think twice about challenging what you are told. Items such as load blocks, extensions, jibs, and rigging must be added to the weight of the load to determine the total load imposed on the crane.ДonвЂ™t hesitate to ask a crane operator for clarification. Load chart notes provide critical information relating to the operation, set up, configuration, and restrictions.ДЇinally, you must account for all accessory weights. Mobile Crane Load Chart Crane capacity chartД®qually important to the load ratings shown on the chart are the load chart notes. You cannot assume that taking load values from the next longer boom length is safe. Keep in mind that a shorter boom length may have a lesser rating. When boom length and/or radius is between the values printed on the load chart you must select the boom length and/or radii with the least load rating. To determine how much load the crane can safely handle you must also know the length of the boom (hydraulic cranes show boom lengths in a row at the top of the load chart), and the load radius of the suspended load (hydraulic cranes show radius in a column on the left side of the load chart). capacity for a two-part reeving will require more reeving prior to making a lift that exceeds 28,000 lbs. A reeving chart which indicates 28,000 lbs. How to calculate crane load capacity?Дoes the crane have sufficient load hoist reeving? Reeving charts indicate the type of wire rope and the number of parts of wire rope required to lift loads. The combined information to this point will lead you to one or more pages within a load chart. Make certain you know the area where the load will be lifted from, the area the load will pass through, and the area the load will be placed.Д«ase lifting capacities on the area with the least load rating according to the working area chart. Over what operating areas will the load be handled? Working Area charts define specific areas of the crane that relate to loading ratings.ДЄreas such as Over the Side, Over the Rear, Over the Front, and 360-degree Rotation lead you to specific load charts. What are the boom and jib/extension configurations? If the lift will be made with an extension or jib you must locate the load chart that provides ratings for these accessory devices.How much counterweight is installed on the crane?.How is the crane configured? Are the outriggers fully extended and set, partially extended and set, or will the lift be made on rubber tires?.There is specific information you must obtain prior to attempting to lift a load. Load charts have become increasingly complex. The crane load chart in the mobile crane industry is long past the days of a single page load chart. You just have to know what youвЂ™re looking for. Similarly, certain information will always be located within a craneвЂ™s load rating chart and notes. You do this because you know these controls must exist to operate safely. You locate the speedometer and fuel gauge, then locate windshield wiper, outside mirror, and seat adjustment controls. Just as you may expect to find certain information when you enter an unfamiliar automobile.
