Blast Proof???
Blast Proof???
(OP)
I had a customer ask me if our cranes are design to be explosion or blast proof.
I am sure there is classification system, and code that would relate to cranes, would anyone have any information on this?
Thank you
JD

We made trolleys & storage racks/pallets etc for stores at a previous employer. At one point we were looking into making some of them blast resistant to help meet IM requirements. I don't remember the racks or trolleys having to meet some recognized standard by themselves.
There were I think maybe grades of how insensitive a munition is, which could include packaging effects, but that's not directly applicable to you.
There are standards for bomb shelters etc but I don't know that they would pertain to cranes.
Either way, based on your second post it seems that your products weren't intentionally designed to be explosion proof.

RE: Blast Proof???
But its really an interesting subject that I would like to learn more about.
RE: Blast Proof???
If your crane is shipborne it might fall under these.

RE: Blast Proof???
To give you some idea, my former companies expert summarized it like this.
All ship equipment was designed to survive a level of shock that would kill (or at least severely injure) just about everyone on board. Essentially after the shock the Navy would 'sweep off' the old crew and install a new crew, the ship itself would be funtional.

Gymmeh,
Are you certain that your customer wasn't referring to equipment that doesn't cause explosions? I know there's a class of electrical equipment that's rated to not cause explosions in explosive atmospheres.
Otherwise, the crane would need to be made from unobtainium. Consider the difference between an MRAP and a HMMWV. A crane built along the lines of an MRAP would have trouble raising itself, much less carry a load.

RE: Blast Proof???
The two cases being
The electricity causing explosion proof, which user can get air or hydraulic driven system (having a remote line run from a safe location)
or the crane is in a location which is volatile and needs to withstand blasts.
I guess I will never know.
RE: Blast Proof???
This test can be applied to subsystems on the crane. We had to comply to this method with some of our airborne computer equipment.

RE: Blast Proof???
503.13 is specific for cranes and hoists in Cl 3 (ignitable fibers or flyings), Div 1 & 2 hazarodous areas.
Specific enclosures are designed and rated for "Explosion proof".

RE: Blast Proof???
Next time someone calls asking for anything dealing with exploding cranes I will know what going on.
RE: Blast Proof???
I can't recall the details but there are standards for this, certainly as relates to electrical equipment.

Electrical apparatus for potentially explosive atmospheres. Flameproof enclosure 'd'
In mining its called flameproof equipment - try searching for that term theres lots of info.
