One mistake I think. The short cables near the battery end have the wire clamps upside down. The rule is never saddle a dead horse, so the saddle side of the clamps should be on the long side of the wire rather than the short looped side. Upside down in the video but right in the rest of the clamps. Nice job ... love the dog!😃
to help prevent the tilting, use your angle iron to create a triangle where your wires converge to the winch (longest end of the triange), with the winch hook attaching to the peak of the triangle. That setup causes the load to remain centered as twist is minimized by point load making your platform more stable if not balanced.
Great build. I'm looking got do something similar in my pole barn. Well done except you may want to change out that threaded rod for a triangular design. Regardless, the design appears to be solid. Also, I just saw your links at the bottom. I just have to LOL!!! I needed a good laugh today.
One of the main changes I would make is take to short cables coming from the two ends of the rod that the winch cable is connected to and hook the winch cable to the two short cables from each end of the rod that would take the side to side motion you got from pushing down on the side out and make it so as no matter where the load is on the platform it would remain flat that and what another commented about was right never Saddle a dead horse the saddle on a cable clamp all ways goes to the side under tension other then those two small things it looks well made
There's a lot of suggestion below, but heres one more. I would have used steel pipe sections as a bushing where the wire rope goes through the osb. That should have been thicker or regular plywood but that's just me. I like the concept of hiding the pulleys. I am looking to mount a 6ft. Long circular saw cross cut jig from the ceiling to be lowered when needed. The wheels you used are garage door wheels? This must not have been a cheap project. I've been pricing components online and they are not cheap for sure.
The sketch factor is strong in this one. I like the charger on the battery. I have a winch I mount under my workbench to drag in dead cars. I have an extra battery (or two) laying around. I'll have to copy that setup.
Ya I know it seems sketchy but I wouldn't have built it if I thought it would fall. There were a good amount of calculations that went into this... I'm no engineer but I didnt want this thing falling.
Echo the comment on Saddling a dead horse. Great build I'm going to copy the design but reverse the direction of the lifting cables to the ends of the platform instead of the middle. Great idea, Keep building and filming ;-)
To fortify the lift rod I would suggest a piece of 3/4" ID pipe as a sleeve over the center section clamped by the 2 inner most nuts. Actually 1/2" all thread with 1/2" pipe sleeve would be plenty.
I would not have gone the route of a battery system for the 12 V winch, the batteries are only going to last 3 to 5 years and they always have problems, instead of a battery, I would use power supply that the CB radio guys used, plug in the wall and converts to 12 V DC that would last years and years and years and you can find them at thrift stores for next to nothing. Other than that your build is kind of nice I definitely like the garage door pulleys.
The Crosby Cable clamps are on wrong at (6:10) in the video and can slip. Always put the saddle on the live end remember "never saddle a dead horse" not trying to be critical just some things I noticed. remember Hind site is always 20/20.
How are you securing the cables on the 4 corners? Also, is it straight into the joist or is there another board running from one anchor point down to the other (with lags holding that board as well)?
Great build! Can you please make a video showing the flow of the cables along the various pulleys or consider slowing your camera movement when showing the entire system on future projects. The item I was having trouble catching was how you attached the exterior cables to the ceiling. I was eventually able to find a frame that shows it briefly. Thanks for sharing and I look forward to more content.
The static mounts on the outer sides of the ceiling are Steel Painted Corner Braces - I think they're 5.5" x 5.5". And because it's a shear load on the connectors for those points, I just used 3, 3.5" deck screws with a few fender washers to keep them in place. It's hard to tell how it all fits together - took me a few tries to sketch out the initial diagram - but hopefully this helps: - There are 8 points of contact on the ceiling: - 4 fixed on the left and right sides (2 per side) - 4 pulleys in the middle - There are 8 points of contact on the raised shelf - 1 in each corner, 4 in the middle - staggered to allow the cables to pass by each other.
Sure would be nice to have a diagram of the cable routing. I built one myself but it works like a bike lift and one end always goes up and down faster than the other so I would like to modify it
Quite a Lot of Work\ Effort, Hope it's serving you Well. *CAUTION!* 'NEVER Saddle a dead horse' 6:08 *8{|* Hope you Changed them around. - other side connections too. 7:44; 8:04 R; 8:17; 8:27 i mention, cause wish others would tell me when i goof & Helps Me Remember. CHEERS!
haha, the wood is going to fail before anything else fails.. 2 min later the threaded rod is almost bent in half. there is no way I would trust that above my head. Just a simple mistake like you made, If you had not noticed that it would have killed you.. The fact that you added a safety on it at least is a little bit better. I hope your safety doesn't have the same issue!! Looks cool though. I want to build one also for a 4ft by 4ft platform for taking stuff to the attic and will fit between the ceiling joists but 1inch bots are being put in from the joist to the platform as safety pins also it's only holding the weight of the platform when at rest so like 100lbs!!
I noticed the rods bending. I suggest replacing the all thread rod with 1-5/8 (41.275 MM) slotted Unistrut. then use eye bolts. Like they did in this video th-cam.com/video/af6NA_BRjyQ/w-d-xo.html .
Your design is not bad, but there are several failure points that you built into the system. Just because you say, “That’ll be fine”, doesn’t mean it’ll be fine.
@@bayfire9982 , I like the overall design, but you suggest here that you did 'calculations', yet speaking as an engineer I can immediately see several failure points and modes that have clearly been guessed at rather than calculated. The bent rod is just one of the telling points (and the first one bent with almost no load on the platform!), and I shudder to think about the sudden failures that are actually quire likely with this rig is you happen to load the platform oddly, or carelessly removes load at one side or end (or somebody else in the household removed part of the load or adds more)....even that beefed up draw bar is not as strong as you think.....It should be replaced with some kind of structure that can better deal with the offset loads and which will not bend as that rod can do.
Ya it does look sketchy, but I didn't guess at anything. The video would be pretty boring if I went through every calculation I did to put up the lift. I took into account the weight of the platform itself (static and dynamic - although the dynamic load isn't much different front static in this case) , max weight of any items on top, distributed weight across 8 contact points (1/8" aircraft cable working and breaking strength, garage door pulley tolerances, sheer strength of 3/8" carriage bolts). Also included the modulus of elasticity of the 2x4's across the spans between the pulleys to ensure the platform wouldn't bend. I then calculated the withdrawal force of the lag bolts and wood screws in the ceiling and walls. Then calculated the bending force of all my angle brackets and shear stress on the wood screws holding them in. There's no way I'd hang multiple hundreds of pounds of material over my head while I'm working every day if I wasn't 100% confident that it wasn't going to fall. And yes, it tilts a bit. I don't care, it works great and all my calculations are well above the maximum weight capacities I built it for. Thanks for watching!
@@bayfire9982 I love your build, I trust your calculations. I do have questions though. How did you determine the load capacity of the ceiling mounting point? Are you “U” bolting onto joists? Are they trusses? I ask because I have trusses, the mfr specifies no load. I would like to do something like what you did.
Why didn't you use a hoist instead of a winch? Hoist has built in brake and is 110vac, no security cables needed or battery with charger. Would have saved a lot of time and money and obviously getting that heavy battery up there.
"There's a little bit of give in this but all of the connecting are strong enough", famous last words.

Awesome idea! The twisting really isn't that bad, and if I used this more I'd definitely add this idea.

If you ran the power for the trickle charger why didn’t you just plug it in? Just curious.

Your cable clamps need to be reversed. The loose end should be on the u of the clamp not on the saddle side.
Good call, I'll be fixing that in the coming days
Cable clamps on wrong Yikes...
Your design is not bad, but there are several failure points that you built into the system. Just because you say, “That’ll be fine”, doesn’t mean it’ll be fine.
Sure, anything hanging from a ceiling has failure points, but based on my load, stresses and other calculations I have nothing to worry about.

Hard to take anyone very seriously who keeps calling 3/8 carriage bolts 5/8 lag bolts.
Accident waiting to happen.
It's been up for over a year, I've winched it up and down dozens of times with full loads and it's going strong. Thanks for watching!
@@bayfire9982 it is an accident waiting to happen. Someone commented on your cable clamps being on backward and he is right. Hope you fixed it.
