Default Fastening winch to concrete wall?

I have 3 jet skis on a trailer and have a difficult time getting them into my garage. There is not enough room to use my SUV to back the trailer in and pushing the trailer and skis is hard, especially up the slight incline and 2.5" lip to get into the garage. I am planning on putting a winch on the wall opposite of the garage door and use the winch to help me get the trailer into the garage, Anyway, I thought about an ac powered winch or even a dc powered winch with a converter but think I will go with an old fashioned hand crank. I need to fasten the winch on the wall which is concrete. Any recommendations on how to screw the winch into the concrete wall. It's need to be a pretty sturdy connection.

Thanks.

Thru bolts with a big backing plate... Easy peasy.

Can't go all the way through the concrete wall or the backing plate will be on the outside of my garage wall! Guess I will look for a screw/bolt that will anchor in concrete and hold a decent load.

Tapcon screws should work.They should come with a bit.

I am not a construction type guy you you can get bolts that have collars that are for concrete. I know you have seen them. Drill an oversized hole, insert collar and bolt into the collar. I expands and holds tight. They use similar for installing car lifts in the floors. As a safeguard, I would mount the winch on a plate, bolt the plate to the wall and use some square tubing angled from the plate to the floor as support against forward pressure. Does that make sense?

I wouldn't put it into the wall unless it was solid concrete (not block). I would put a 1/2" eye bolt into the concrete floor near the wall, mount a winch on a plate so you could remove it easily when not in use. I have seen mounts in 4x4 magazines to be just slipped over a trailer ball.

Hook to the eyebolt (or better, the one I described above)


Add one of these 2000lb winches for $69 at Nothern


Put it on a shelf when not in use

SIMPSON makes a tapcon on steroids..2000# pullout, 1/2" diameter. Drill a hole, screw it in. You can also drill a hole and epoxy all thread into it.

You need to be using an epoxy anchor of some sort.

Hilti HY150 and some threaded rod should do the trick. Follow the directions for proper embedment & cure time and you will never have to worry about pull out.

The larger the steel plate is the more spread out the four anchor bolts become. The benefit of having the four anchor bolts spread apart as much as possible is the force applied to each individual anchor bolt is more of a diagonal pull apposed to a direct straight out pull. The more the diagonal pull you can apply to your anchor bolts the stronger the hold will be to the wall.

What kind of "concrete" wall do you have? Is it poured in place, precast, or cinder block? You would be much better off putting the anchor in the floor. Use the expansion bolts kingair posted without epoxy the two are not meant to be used together. Dont use tapcons they dont have the holding power for what your looking for. You could use the hilti HY150 and allthread. But if I remember right the Hy150 is kinda pricy and if you ever want to remove the anchors you'll have to grind off the top, with the expansion anchors (usually only a couple of bucks each) you can usually just pound them down into the concrete if you drill the hole deep enough. By putting the anchors on the wall youll be pulling inline and depending on the material you could easily pull them out. Before a major career change several years ago I worked for a precast concrete company building parking decks as a field project manager working with the engineers to figure out repair details which always meant anchoring something in concrete to hold something else usually weighing many many tons so I have a little bit of experience in the subject.

Do the Wedge bolts that have been shown, and mount it to the floor right at the wall like Afish suggested. It'll put everything in shear, and increase the weight you can pull.
There is also a plug, threaded on the inside, that works like the wedge bolt, that sets in the hole, and then is seated when you thread a bolt into it and tighten it. I used these in the boat shed for the eye bolts I have for tie downs. When I don't need it, I can unscrew the eye bolt, and thread in a bolt to keep the crud out of the hole. The eye bolts were supposed to hold alot(thousands of pounds) if I remember correctly. I drilled a 5/8" hole for the piece that stays in the concrete.

The punch set anchors katkt suggested would be excellant just make sure you dont drill to deep you want the end of the anchor flush with the concrete if there going to be used in a shear connection. Also if you use them make sure you get the right length bolt because the bolts only go in so deep. I dont know if Home Depot or Lowes carries them though you may have to check graingers or some other supply house.

So is there a problem using the two of them together? Why are they not meant to be used together?

Good thread... We're all suggesting stuff that'll pull his 31 Bert up a hill and into the shop when all he wants to do is drag a little trailer over a 2" lip in the concrete
