    Wire Rope Damage

    You are correct and this is typically how the manufacturer specifies this termination be configured. There are manufacturer and model, specific tolerances for wedge protrusion below the socket, length of rope tail and distance between that short piece and the bottom of the socket. When done...

    Wire Rope Damage

    I think its more likely that the socket head recess in the drum anchorage clip bolts were damaged (stripped) rendering them nearly impossible to remove with an Allen wrench. I have experienced this very scenario with these hoists. Alternative measures would be needed to extract the bolts (use...

    Wire Rope Damage

    I am leaning towards installation error. If the rope was installed by paying directly off a shipping reel, any twist in the rope would remain in the system and work its way back toward the end termination. Often times this kind of twist is observed immediately after the initial run test and the...

    30 T overhead crane with a binding problem

    Ok, I was under the impression that only one drive was controlling both motors. Sounds like you have a handle on things. If you have any input and flexibility in the purchase, I highly recommend replacing with Power Electronics drives. They are very robust and user friendly with great tech...

    30 T overhead crane with a binding problem

    Is the problem limited to any localized area of the runway? If so, disable the brakes from the motors and test bridge through that localized area. Observe the bridge wheels and how the wheel flanges interact with the rail. Never assume that because rails are "perfectly straight", they are within...

    Extending boom while under load.

    Extending boom while under load.

    Why not use the overhead crane and do a Planned Engineered Lift? The 23T load (46,000lb.) is within the allowable 125% (50,000lbs.) of the 20T crane load rating. It appears this load will only be handled twice, setting it in the test stand and then removing it from the test stand, also meeting...

    Can anyone identify this crane?

    Whatever kind of home, shop or business that intends to use the crane will likely have to be insured. Insurance costs are the driving factor in keeping things safe and on the up & up at home or around the shop. An insurance audit whether it be for home, business or otherwise is going to raise a...

    Can anyone identify this crane?

    You might need to take a closer look at the structure to determine if this is indeed a manufactured product or simply something designed and constructed by the owner. If it were made by a manufacturer, my guess is it could be an early, Alfred E. Box Company model (commonly known now as Shaw-Box...

    Crane Certification

    My understanding is it depends on what your doing... these excerpts from NCCCO FQA: OSHA 1926.1400 covers cranes in construction only. For crane work in general industry, refer to OSHA 1910.180. There are no federal operator certification requirements at this moment in general industry [§...

    Cable lube

    I prefer Crosby Vitalife 400. It penetrates well and is not tacky. Best of all it is transparent and allows continued visual inspection of the rope. https://www.thecrosbygroup.com/products/wire-rope-lubricant/vitalife-400-wire-rope-lubricant-standard/
