The top two modes of overhead crane and hoist failure, per research from noted former P&H engineer Charle Totten, are wire rope and rigging issues related to cowboy operators and bridge/long travel (along the runway) machinery resulting from out-of-tolerance rails and runways. I can help you find site services and components to make any aspect of your overhead cranes work better and safer. Finally, if there are irreconcilable differences or a casualty, I perform expert witness work and can help settle legal disputes arising from these problems.
