I know there is the requirement to have a latch and it must be operating correctly etc but what if the latch causes more risk than not having it?
If it is risk assessed and documented why it is safer to not have a latch at all, is it acceptable?
Has anyone had experience of different designs of hook, where the latch can be released from a distance?
Thanks
Chris

I assume that your posting about lifting chains and hooks etc. If this is the case as you state. Why not buy some lifting gear that doesn't have a latch on. Basically speaking , PUWER and LOLER state suitable kit and equipment

Hi Toecap,
Thanks for the reply, Just to confirm as i was not very clear, ideally i dont want to bring additional pieces of equipment into the equavion. Its just something else to go wrong. Currently the crane hook attaches direct to the ladle with no chains, and that is the way i would like to keep it.
I have seen the chains with "C" hooks and also "safety hooks" where the latch opens outwards but is held tight against the hook body when lifted. Ideally i would like replacement hook for the crane but i expect this is going to be hard to find which is why i was asking about the risk assessment route and the removal of the latch.

Would you not consider using a shackle? I recall in the early days hooks were moused. This was a practice of placing some string to close the opening of a hook. This prevented any attachments on the hook being displaced.

A shackle would not help as you would still need to release the latch on the hook from the shackle, as with mousing, you still have to be over the molten metal to do it.

I believe what you are asking for is the "C" type hook, it has no safety catch and is a slightly different shape to other hooks and it looks like a "C" at the top of the hook curls down further which prevents slings, etc from coming out, you should be able to find them at any supplier of marine related lifting equipment.

Some hooks, for straight lift only do not have a safety latch fitted, i.e. gantry cranes in steel works lifting molten metal vats. What you have to be sure of is that it cannot be used for other purposes...

I believe that the hooks with a latch on have a slightly wider 'mouth' than those without and also a slightly different shape so if you want a hook without a latch on it then you will need to buy a hook without a latch. You can't simply remove the latch from the one you already have.

The only other option is to consult with a lifting gear special company. There has to be something out there

You cant remove the latch or you are changing the construction of the hook to its design This would then make the Test Cert null and void. As previously stated replace with a C Hook if it can do the job then you will also have a New Test Cert supplied.
Good Luck
