The document is a lifting plan checklist for lifting a pipe rack structure weighing up to 2,270 kg using a STC250 mobile crane. It details the load description, type of crane and lifting gear to be used including slings, shackles, and main line below the boom. The total weight of rigging and scaffolding is calculated as 700 kg, bringing the dynamic load to 4,453 kg which is within the crane's lifting capacity of 5,000 kg at a safety factor of 1.4 and 71% of its safe working load. The prepared plan was approved.
