This is the hopper inside which operatives must climb to clear out the grizzly bars
Weight not possible. It’s a floating hopper on the end of a conveyor using a 10t winchThat sort of cleaning work needs to be designed out nowadays.
Have the grizzly bars and one side of the hopper pivoting and a ram or hoist to pivot it out to clean it.
Ship To Shore Slag & Clinker for CementIf designing from scratch, I would of had a small cantilever beam welded perpendicular to the column next to handrail, that had a couple of eyes welded/bolted to it. Stand on the platform into the hopper, clip on and climb in.
I would suggest something similar, but bolt the arm to the column instead.
where’s that place Brad ? Is it a ship to shore sand plant ?
No, a 90 ton excavator on a ship unloading through the night makes short work of anything sticking out.Is there no structure well above to use a scaffolders reel. Is that at the same place where you were going to repair the mooring pillars?

This is basically what I’ve put to them. Awaiting a response.Not your problem I know but any work incorporating a fall arrest system also needs a rescue plan. I'd love to see what plan they come up with for climbing in and out of that. There also seems to be a metal walkway on the off-side of that hopper that's too close for a fall arrest to deploy so it doesn't even seem to be appropriate. Needs an inertia reel.
If I was tasked with the job of mitigating work at height risks in that location I'd be looking at a sliding handrail that can be rolled back out of the way of the digger. If it was properly designed it could be deployed in less time than it takes to put a harness on.
Bit of a nightmare, I would keep well out of the design/testing element and just weld whatever they told me to weld (in writing) and let someone else be responsible.
Just not possible.Weld a pipe handrail around the hopper. 950 from the highest standing point and no more than 470 gap.
Yeah in case you fall over the sides.Looking at it, I was under the impression that the fall arrest was in case you fell over the sides and not into it ?
Just not possible.
This operation is quite hard to understand unless you’re standing in front of it.
Hand rails are not an option really.

That’s what we call rigging for rescue in rope access.I've had to put anchor points on a machine in the past. I just put them where they wanted they were then load tested and every 6 months get inspected and re tagged. This was going back a good few years.
It a bit of a mind field doing any fall arrest as you have to risk assess everything, and have to have a rescue plan in place if the person is suspended. We use a fall arrest system where we are able to be lowered to the ground by someone else. It's a backpack incorporated in the harness. Sorry for poor description there.
