Mobile Crane Safety & Critical Lift Planning (Aramco GI 7.027)

Heavy lifts exceeding 40 tons or executed within operating petrochemical plants are classified as Critical Lifts in Saudi Arabia. Under **Saudi Aramco General Instruction GI 7.027**, a critical lift plan must be prepared, reviewed, and signed before outriggers are set.

When is a Lift Classified as Critical? A lift plan is designated critical under any of the following parameters: - The load exceeds 85% of the crane's rated capacity at specified radius. - The lift involves two or more cranes in a tandem lift arrangement. - The lift takes place over operating hydrocarbon pipelines, live electrical lines, or occupied structures. - The lift involves personnel hoisting or blind pick-and-carry maneuvers.

Key Elements of an Approved Critical Lift Plan 1. **Ground Bearing Capacity & Outrigger Matting**: Verification that outrigger pad pressure does not exceed soil bearing limits, utilizing heavy hardwood or steel crane mats. 2. **Rigging Tackle Certification**: All shackles, wire rope slings, spreader bars, and synthetic web slings must possess valid TPI load test certificates and color-code tags. 3. **Certified Rigger Level 1 Sign-Off**: The lift plan drawing must be checked, stamped, and signed by a certified Master Rigger Level 1.
