Certified Crane Care Tech Tip Training Video: Pre-Operational Hoist Check
Please take the time to watch this excellent instructional video on how to conduct a pre-operational hoist inspection. Every operator should inspect their hoist pre-operation before EVERY use to ensure they are operating a safe unit. All operators should follow these steps before engaging a hoist for their own safety and the safety of those working around them. From visual inspection of the hook and chain to testing the limit switch and brake, this checklist will keep your equipment running properly and make a safe work environment. This video was created by the Columbus McKinnon Training Department.
Recap of Pre-Operational Hoist Inspections:
1) Inspect warning label, check for "Out of Service" tag
2) Check pendant for cracks, loose wires, frayed wires, and proper button markings
3) Test the "Up" and "Down" functions
4) Inspect the hook and make sure there is a latch (unless it constitutes a hazard), look for heat damage, stretches, excessive wear, nicks, & gouges.
5) Make sure the locking pin is properly secure and that the hook can swivel on its base
6) Run the hoist hook up and listen for unusual noises, look for leaks, make sure its mounted properly and that the hoist is properly reeved.
7) Run the hoist up until you trigger the Limit Switch, to ensure it was set-up properly and to prevent two-blocking
8) Repeat step 7 moving in the opposite direction until your limit switch is engaged. While performing this task, you can do a link by link inspection of the chain, looking for nicks, gouges, cuts, abrasions, wear, heat damage, and weld splatter.
9) Should anything concern you or whomever is operating the hoist, immediately stop using the hoist & take it out of service by tagging the hoist with an "Out of Service" tag.
10) Run the hoist down until the lower limit kicks in kicks in and the power kicks out, ensuring that the lower limit is set properly.
11) To test brake function, use a load of 50 lb. per strand of chain. Move the weight into position and attach your hook to your weight.
12) Raise the weight slightly, stop, and observe. If you don't see the weight moving at all or drifting downwards, this ensures your brake is operating properly.
13) Lower the weight back down and remove the hook from the test weight.
14) Finally, observe your environment and remove and obvious safety hazards.
