Important Parameter of Crane Lift Permit

As the construction of heavy industry developed the load limiting or moving equipment usage became indispensable - we saw cran on construction sites on all four sides operating day night. To ensure safe operation of the crane lift permit is the most efficient tool used on site, and it helps employers and works to avoid undue accidents due to misuse of the machine. Below are the important parameters of crane lit permit applicable for all types of cranes and can be a helpful tool for an effective crane lift permit.

Crane Specification

• Date
• Description of Load
• Model of Crane
• Weight of Load
• Boom of Length
• Weight of Rigging and Crane Block
• Jib Length
• Total Erection
• Load Maximum
• Radius of Lift
• Percent Crane Capacity at Maximum Lift Radius
• Crane Capacity at Maximum Radius of Lift radius
• Non-Engineered Lift
• Engineered Lift
• Attach important documents including supporting rigging Study, drawings and lift plan for all Type ‘B’ And Type ‘C’ engineered lifts.

RIGGING TOOLS REQUIRED – SIZE AND CAPACITY

• Shackles
• Spreader
• Slings
• Tailing Hook-Up

LOAD AND LIFTING LUG

1. Does the weight of the load have been documented or accurately calculated?
2. Are all items that will be lifted with the equipment included in the weight?
3. Do the lifting lugs that will be used to lift the load be designed for that purpose?
4. Will the correct shackle with the lifting lugs be used?
5. Will only in the strong direction(s) of the lugs are considered for lifting lugs be loaded?
6. Do the lifting lugs are free from any detectable defects or damage?
7. Do the load is checked for loose or unsecured items, which might fall off during the lift?
8. Will the crane hook be over the center of gravity at the initial pick for a one-crane lift?

RIGGING TOOL

1. Have the capacities of the slings and shackles been checked for the load?
2. Have the slings and shackles been visually inspected for defects or damage?
3. Do the sling angles are considered when checking the capacity of the shackles & slings ?
4. Does the center of gravity is considered when checking the capacities of the shackles & slings? 
5. CRANE Is the Load indicator with load cut- off installed on the crane and is it less than 90% of allowed crane capacity?
6. For a crane with no Load indicator the load is it less than 80% of allowed crane capacity?
7. Do the operators perform daily inspection and operational checks of the crane? Does the crane set up according to the manufacturer’s specifications?
8. Is the crane supported by approved crane mats? If the lift employs more than one crane, do both cranes load as per their safety capacity limit?
9. Has the soil been inspected and determined to be adequate?
10. LIFT Has the rigger/signaller checked the radius of the lift?
11. Is the lift area cleare and free of all types of hazards, equipment, live electric wires, or any material stack?
12. Is everyone warned to stay away from the lift area and also barricade the area with proper indicators/signs?
13. Is the wind less than 32 km per hour?
14. Do risk assessment of collision between boom and equipment is done - is there any mapping or has the rigging layout been made?
15. Is there a dedicated designated “Signalman-in-Charge” for the lift?

NOTE! All questions should be answered yes, no, or N/A (not applicable). The Rigging lead must approve any checklist item answered by “no”.
