WW: Sudden Drop

A few weeks ago, John Truempy of ALOA Institutional Locksmiths sent me a link to his library of door-related photos.  What a treat to flip through his collection – I’d love to see your door photos too!  Today’s Wordless Wednesday photos are just a few of the post-worthy ones in John’s library.  8 floors – YIKES!

    Wow, looks like a old cargo/crane lift door to get big pallets or objects up to the higher floors easily.

    At the first picture, I thought the dangerous drop referred to the overhead beam falling when the door opens.

    Lori, this door is obviously not meant for human passage. Notice the beam that passes through the head. The photo doesn’t reveal it, but there is probably a trolley or hoist that is mounted to the beam. It is meant to roll out the through the opening to hoist whatever is required for this facility. I would add one more safeguard; a removable cross bar painted safety yellow.

    It is not the fall that hurts, it is the sudden stop

    I think the owner covered any liabilities 🙂

    I wonder if it would be practical to use a dutch door constructed in such a way that unlatching the lower part would require first opening the upper part and then reaching through the opening? When the crane was being used to lift things that were short enough to fit over the lower door, it could simply be left closed, and in cases where the lower door needed to be opened the hazard would be made obvious to anyone reaching the outside latch. If the door opened outward, such a design could be dangerous if an unexpected gust of wind pulled the door open while someone was operating the latch, but since it opens inward any unexpected wind force on the door would push the operator away from the opening.
