Lessons to be learned

The main lessons to be learned could be summarized as follows:

• 1. Always know the weight of the object before a lift is made.
• 2. Assess the Lift Plan - boom angle / radius / weight / size of crane required / number of cranes required - built in safety margin.
• 3. Select the appropriate Lift Crane/s - size - type / mobile / crawler- confined space - type of foundation - swing area - walk with the load.
• 4. Verify that Foundation is firm and capable of supporting the load being generated by the Planned Lift ¿ requirement for soil compaction test - need of crane mats / plates to be assessed.
• 5. First initial Lift made and held a half meter off the ground - thorough check of all foundation support, rigging, lift radius / plan, crane stability / track-outrigger movement.
