We can help in this process by helping to create a lift plan with you whether it is a standard lift, non-standard lift, or an engineered (critical) lift. We want to make sure you have a successful lift and that starts with proper planning. Even the most standard lift needs a simple lift plan to make sure that the lift is within the limits of the equipment and is accomplished safely.

Some of these require a Professional Engineer to review and approve.

Pre-lift meeting with all personnel involved with the liftĪ critical/engineered lift is considered the riskiest and usually involves many documents to ensure everything about the lift has been considered.Gross load is equal to or greater than 25 tons but less than 50 tons.Īt a minimum a non-standard lift plan should include:.Gross load is less than 75 percent of the crane manufacturer’s load chart rating at the working radius.Īt a minimum a standard lift plan should include:Ī non-standard lift is slightly riskier than a standard lift and there are a few more items to include:.An example of this may be unloading a load of secondary structural beams from a truck with a rough terrain hydraulic crane.Ī standard lift could be considered any lift that is not a non-standard or a critical/engineered lift. It is something that is lighter in weight, doesn’t take up much capacity of the crane, and is typically a common lift. Many accidents occur during the erection and dismantling of the crane so this should not be overlooked.Ī standard lift is usually deemed a low risk lift. There should also be an assembly and disassembly plan for the crane. A survey of underground infrastructure should also be completed prior to lifting operations to make sure the crane isn’t set up over an item that could rupture beneath it. It shall also be set up on proper matting as required on firm, level ground. In all cases, the crane shall be set up properly according to the manufacturer specifications. We should note below that gross load means all of the load acting on the boom or jib tip and any other deductions that need to be taken into account. We will walk thru some criteria that could be set forth for a standard lift, a non-standard lift, and a critical/engineered lift. Some organizations just have two levels of lift plans: standard or critical/engineered. Another example could be a standard lift, a critical lift and an engineered lift. Each of these has criteria that build off of each other. One example of this setup is having a standard lift, non-standard lift, and a critical lift. Most organizations have created certain levels of lift plans based on the level of risk involved with the lift. To mitigate this risk, it is best to create a lift plan to help vet out the risks involved and make everyone involved aware of the risks. When completing lifting operations, there is always a level of risk involved.
