Anchor plate for garage

[mudpaws]

Hey folks,

I have a 30-odd foot driveway that slopes upward from the street. What I'm looking to do is attach an anchored plate to the floor in the center rear of the garage. That way, I can winch or "come-along" any vehicle up the driveway, into the garage if it's immobile or without an engine. Please give me any ideas about the plate thickness and width, the type of hoop to weld to it, anchoring to cement ideas, and maybe the chain hoist (come-along) load capacity. The biggest vehicle will probably be a full-size Ford or Chevy pickup, FJ55s, 60s, 80s....Thanks!!!

I could have used an anchor point like this a few times. Subscribed.

get a big gnarly eye and hilti it somewhere secure. My dad has a similar set up.

More info needed. Are you planning to dig into the floor and attach to the rebar already there? Are you planning on driling holes and sinking, say for instance, 1/2 inch by 8 inch bolts? If you are planning on attaching to the back wall I would suggest through bolts with equal size plates on each side.

To "foreal", that's exactly what I was thinking!!! I just have to find a big enough "closed eye" with a long threaded bottom, say, minumum 3/4" thickness...and borrow a Hilti, drill the hole and sink a concrete anchor. I could basically drill one hole for the "eye" and sink into an expanding anchor; or get a rectangular welded plate made with an eye or similar welded to it; then attach that plate to my garage slab with 4 bolts & washers into holes containing expanding concrete anchors. I would think the latter is overkill, but then maybe that's what I'm after! What do you think?

Check with a trailer supply place for a closed eye with the correct capacity rating.

The winch points I've seen "in the wild" were sealed into the rock with some kind of epoxy.

if you don't care about removing the thing, you could just drill a big vertical hole in the slab (if it's thick enough - check first) and simply anchor it in place with some expanding cement. The force will be horizontal or down so it's not going to come out so readily. Finding a large strong anchor to bolt a big eye in won't be so easy or cheap, though, if you want it removable.

Or, any large pintle hook or lunette with 4 bolts should work too and probably easier to deal with too. A quick look at tables with the shear strength of bolts should tell you readily what size you'll need.

Either way, this will require some care and thought to avoid trouble in case something lets loose while winching up.

I have a grinder stand on the far edge of the garage and it is bolted to the floor with four concrete anchor bolts. The base of this stand is use to pull a dead vehicle into the garage using a pulley block (and a winch) or a hand winch (not preferable)). My driveway is not on a slope so not a lot of dead weight is being pulled but you prolly will need larger anchor bolts.

I would drill four holes and epoxy in 4 threaded stainless steal rods, then bolt down a plate. I would make the holes 8-12" apart to spread the force. I would use 1/2 threaded rod to give the epoxy more bonding area. Should hold anything you throw at it.

I wouldn't use anchoring bolts since as you cycle the hardware the stress will damage the concrete holding them in.

i drilled 1 and 1/8 hole through the floor 18'' deep .the put a 1" black iron pipe flush with the floor the bottom was welded shut. i welded a ring to a1''dumbell bar and drop it in the hole when i need it.

Pictures?

shelfboy1 has the right idea. It's there when you need it, and not in the way. I don't have as much weight to drag around, so I have a couple lag bolts in the 8x8 vertical support timber in my barn that hold a plate on there with an eye bolt. It's strong enough to hook a winch line to pull the truck out of the snow when stuck in front of the barn.

You need a fairlead at the front of the garage

If you have much of a slope and you mount the winch low, you could tear the heck out of your winch line and/or concrete floor if you don't have something to act as a fairlead at the front lip of the garage. I used a long (~11') heavy piece of 2x12 and had some helpers stand on the ends. The first time I did this I was using synthetic winch line so I was focused on protecting the line. The 2nd time I used the wire rope and cut some nice grooves in the board. If I make this a regular practice, I might rig a roller and use the 2x12 as a baseplate.

PS - I was using a vehicle mounted winch so I had a snatch block anchored at the back of the garage, not the winch.
