If your business has never used a mobile crane before, it's possible you don't know the most important items that need to be checked before you use it. The majority of accidents involving mobile cranes deal with dropped loads due to improper training of the operator, improper rigging, or incorrect lifting device. These incidents can be minimized by doing preventative checks such as the following.
Test Run
Before you put the crane to use on a job, you need to run it through a test to ensure it is in good working order. This means you should test the crane through the full length of the runway and bridge span. You need to look for any obstructions that can interfere with the movement of the crane. Test the crane's motion and travel speed and ensure it meets the designed specifications. Look to make sure the controls will go into neutral and make sure the brakes are in working order.
When the Crane Is Off
Once you have done a test run of the crane, shut it off and engage the hoist switch into the 'up' position. The hook should not go up while the crane is turned off, so ensure this is the case. While the crane is still off, check all other motions the crane performs to make sure there no movement on any of them. After you have completed that, turn the crane back on and raise the hook and test its upper limit reach. Look to make sure that the actual movement of the crane matches what you are telling it to do.
While you are performing these actions, look for any cracks, bending or wear in the hook and carrier structure. It's a good idea to look for weather damage as well. Check out the hoist ropes and chains and that any hoses are free of leaks and the riggers are working correctly. At the same time, check that the wire rope is not twisted or damaged and that all functions are working.
Check the Boom
You need to check that the boom is free from damage and wear and is working safely and properly. Check all indicators in the cabin to make sure that they are functioning and lighting when they should be. Take a look at the load capacity rating, end connectors, and load attachments, and keep an eye out for damage and wear.
Finally, make sure that the operator's manual is located in the truck for easy reference. Make sure you give any operator proper training on the equipment before allowing them to work on their own. Contact a company like Radius Projects to learn more.
