I live on a hill and there is a small flat pad before going into the garage, the garage houses more important things than cars like Kayaks and fishing gear along with plex server and lots of other things.

When I back the trailer up to the pad I cant unhitch the trailer due to the car pointing down, I did consider changing the coupling but put it in the too hard basket as I have a two hole hitch and most others are four hole and need plates and other things welded on to make it work.

I can push the trailer up the driveway if it is empty, but add a kayak and gear and it is getting a bit heavy and dangerous.

So I bought a hoist and mounted it to the ceiling ( I could not find a 230V winch )

I tried it out today and when we try and pull the trailer up the driveway the angel of the cable trips the safety switch.

SO, to get the cable running straight up and down I need to anchor a pulley to the garage floor.

My first thought was a larger version of this, but I cant find one.

https://www.bunnings.co.nz/ramset-8-x-45mm-zinc-plated-dynabolt-eye-bolt_p0777766

The down side it is a toe stub hazard, the upside is when we leave ( were house hunting for a flat section due to Mrs Sattv having poor mobility ) it is unscrew and leave.

My next thought was a larger version of this ( does not need to be stainless )

https://www.bunnings.co.nz/zenith-12mm-stainless-steel-square-eye-plate_p4220813

The down side is my toe is still going to find it and it will be harder to remove and reinstate, but the up side is it should be stronger as it has four anchoring points.

So if anyone knows where I can get larger versions preferably in Auckland so I can have a look and make an informed decision that would be awesome.

The hoist is rated to 250KG but I dont think the trailer is that heavy as I can push it up the hill on my own with difficulty.

Cheers

You can get recessed ring mounts. You'd need to make the recess for it to sit in but they're cheap enough to leave in place.

I just saw the same thing in Bunnings, great idea but how do I create the recess?

If I was pouring a new slab I would put one in.

you can chisel concrete easy enough.

however i would check if you have rib raft flooring. if you have, the concrete may be to thin in places.

I have just googled rib raft flooring and I dont think we will have that, we were built in 1966.

You do need to check the weight of your trailer (plus the weight of any load on it) before proceeding any further.

If the trailer is a commercially made one the manufacturer should be able to tell you.

I haven't seen your trailer but they can be quite heavy.

The last thing you want is it taking off on you.

Do you have an angle grinder? You can get diamond cutting blades for these for trimming tiles/concrete etc, and a few shallow slices into the concrete with this and then some careful chisel action would work to make a relatively tidy recess.

…. or if you have (or can hire or borrow) a renovator/multi tool, with a masonry blade to make close cuts, then clean it up with a small coal chisel as per Mehrts.

Sometimes I just sit and think. Other times I just sit.

Install a Ramset Dynaset drop in anchor. It’s essentially a female thread that will sit recessed into the concrete. Only a few bucks at mitre 10, M12 size would be plenty.

Then just screw in an M12 eye bolt (also only a few bucks) and you are sorted. No trip hazards, the eyeball unscrews easily when you need it 👍

Brilliant, I did not know they existed, I saw the the eye bolt earlier but wrote that off as I did not know of a floor socket.

I will look at this tomorrow.

The instructions say that it does not have to be deep either.

The tool should not be expensive but to be honest I dont think the proper tool is probably required for a one off home job.

You’re welcome

No special tools are required. You need a hammer drill to make the hole in the concrete, and to set the anchor ask you need is a hammer and a pin punch or a piece of metal that can fit down inside the threaded part and push the expander down

While you're in Mitre 10, buy a grub screw or a dome-headed bolt that is the correct size it fit inside your anchor bolt. When you don't have the eyelet in, put the bolt in so that it doesn't fill up with dust/dirt/anything else on your shed floor, and make difficult to get the eyelet in next time.
If you use a domehead or grub screw as opposed to a standard bolt, you're much less likely to find it with your toe.

Thanks, I did not think of that, the grub screw is an outstanding idea.

There's a couple of things you should look into. Assuming that you are converting an upward pull from a hoist to horizontal this multiplies the load on the redirect point. https://www.exploringoverland.com/overland-tech-travel/2020/4/19/not-so-simple-the-simple-redirected-winch-pull and whether the anchor point can take sideways loading. It may be that your load is so far within the capacity of your anchor that these don't matter but you should at least factor it in.
