All shipping containers, one -trip or used, could be exposed to some degree of deterioration in some of their components.
Doors are one of them.
They are normally attached to the rear corner posts, each with 4-5 drop-forged steel hinge blades per door. The hinge pins must be lined up correctly for the doors to be free to fully open and close. The blades allow 270-degree opening which allows the doors to swing back against the container sidewall, doors should be aligned and level, both top, and bottom, and if somehow they receive a blow they may become bent or twisted and out of shape, in these cases where the container frame is racked, the door gear will not operate correctly, extra strength would be necessary to open them with a great possibility of injury for the operator,
Opn-Bar, designed and manufactured a safety leverage bar, a door latch handle extender, the perfect instrument for opening and closing of shipping container doors and locking mechanisms found on conventional style (side by side) doors, making this task to be a great deal easier.
Great for opening shipping and cargo containers doors hard to open because iced over! or any of the situations explained above.
Door gaskets or seals
Rubber gaskets are fitted to the container doors during the manufacturing process and prevent water ingress.
Door gaskets are designed to present two or more fins against the structure or adjacent door.
These are generally flexible but when the gasket is damaged, they may become hard or blocked thus jamming the door closed, or preventing it being closed.)
You might think that all shipping container doors were equal but according to these amounts of different rubber gaskets, I don’t think so, take a look
The lockbox is a steel box welded to the right-hand door which overlaps a staple welded to the left-hand door. A padlock, normally type CISA type 285 66 can then be attached inside the lockbox through the staple and is then protected from direct attack, hindering attempts to gain entry to the container.
