How to prepare for a third-party crane inspection


Most crane inspections are done on an hourly basis.  Therefore, it pays to be prepared.  Have more than one unit to inspect, if possible, so that the cost of mobilization is amortized over more than one unit.

1.     Have a multi-sheave hook block reeved on the main hoist at least 4 parts, so that all of the wire rope can be inspected by putting it in the air.

2.     Have the machine(s) set up in an area where the boom can be lowered to the ground, so that it can be fully inspected. 

3.     Have a test weight of 3 to 5 tons.  The test weight should be something easy to rig, such as a Jersey Barrier, Concrete Deadman, Crane Counterweight, Air Compressor, etc.  These items have known weights, so that the inspector can not only check the winch/hoist & brake, but also the calibration of the LMI/RCI or whatever load indication device is present.

4.     Make sure that the machines have their Logbooks, Operators Manuals, Fire Extinguisher (10BC), and Capacity Charts on the rig(s).

5.     Have the operator familiar with the machine available to run it. 

6.     Have both hoist lines out if it is a two line machine. 

7.     If the inspection is scheduled to inspect at a new job-site where the crane is being erected, try to time the inspector's arrival for when the boom is together, but not put into the air.  It will again save time and your cost will be lower.
