A used crane can be one of the best investments you’ve ever made if you are careful in the selection. The following guidelines may be a useful checklist to carry with you when you are in the market:
- Look for cables with flat spots or broken strands.
- Check all pins and bushings for any loose or “sloppy” operation.
- Extend crane to its limits and observe the smoothness of the extension. Binding could indicate a bent tube. Do a visual inspection for the same.
- Check for any ewear on top of the main tube or first slider. Also look for worn ladder rungs which may indicate a bent tube.
- Check crane’s rotation for sloppiness or loose operation.
- Check the gear pack for sharp edges on the teeth or bent shafts.
- Look for brass dust or shavings in the base. Boom up to 85 degrees and watch for movement in base pedestal. Either indicates a worn rotational mechanism.
- Check all mounting bolts on crane base. Loose mounting hardware will cause cracks in base plate and/or can bend the truck chassis.
- Check packing seals around hydraulic cylinders for leaks. Also check hydraulic hoses for worn or weathered conditions.
- Check all outriggers to see if they are bent. Bent outriggers almost always indicate that the crane has been abused.
- Remove safety covers and check all belts and bearings.
- Careful observation of the above items may save you thousands of dollars in potential repairs.
