Where's your disclaimer? "The things you are about to see are not real. These stunts are done by professional mechanics. Do not try this at home." You're either very brave or crazy!
I THINK......... -I can see the main feature of your postless hoist...........it would absorb MOST OF the motion in case of an earthquake??????????
He lives in the heart of the land of the shaking earth... It's much safer to hang something from a strong beam than it is to try and balance it on two or four shaking pedestals. Should hang it by just one of those new Ford truck bed bolts and do an "alternate" commercial for FORD!
Uh, I would be a bit afraid to stand under that...would I be covered if it fell on me...other than by the car?
those look like some fat *** cables - ***uming those are wire ropes and there is no weak link. the truck prolly weighs a ton - ton 1/2 without the motor - depending on what it is tied to - it is safe.
Spent many years in a shop with large overhead cranes, working for a power generation company making steam and nuclear boilers. I have seen cables used as large and larger than yours picking up that much weight and much more. Have also seen cables break, loads shift, and parts fall killing people. Regardless how safe it looks, how big the cables are and how well secured your beam rafters, be afraid...be very afraid. Alway used two methods to support a car at the same time. As in airplane technology... There's a reason for redundancy.
Should be safe! The wire rope we use on 24 foot long swing stage( to work on windows) is 3/8 inch, one on each end. Looks small when 20 stories up! But very strong!................OLDBEET
I get spooked out just reaching under a car to take the oil plug out with two jack stands, a jack, and a spare tire thrown underneath. EF that. My favorite jack stand is a tall curb.
Good advice for this so called tech, can't see any secondary support measures. Hopefully ayone using an idea will do so.
I couldnt have decribed my feelings any better. I seriously freak myself out sometimes doing just that reaching under to take the oil plug out.
I work on bigger constuction sites with multiple tower cranes, mobile cranes and other lifting devices. never would you see anyone work under a live load, ever. that system looks good for moving a car but not for working under even the glazer's on a swing stage wear a body harness with lanyard and rope grab to a separate line in case the swing stage support fails. I have a crane like that stacked up in my parking area waiting for ***embly in my shop. it will come in handy picking bodies off frames and unloading motors and a million other things, I plan to use the hell out of it!

Working under a suspended load is against OSHA standards. Not to mention very dangerous! Using chain to lift the load is really not a good idea because a single point failure (broken link) will cause catastrophic results. A Wire rope sling is more accepted because it does not fail in a single point. Multiple strands must break before complete failure. This is ***uming the load is within the design of the sling and the sling has been proof loaded. Build yourself some strong stanchions for the vehicle to rest on and live to enjoy the test drive.
HAHAHAHAHA.......thats ****in nuts. you couldn't pay me enough to work underneath it. if you suspend it, put some post on each corner. the kind of jacks the muffler shops use.
Allright I would'nt get uner it either its just how I have to get stuff to my workspace the crane an lift 10 tons but our cables usually fail when the have a couple thousand on them not a pretty sight!! And yes I was nervous moving my truck that way, the comination of cable, chain and old welded strongback is kinda iffy!?!?!? But it makes for good photos!
All you guys just better stay off the San Francisco-Marin Golden Gate Bridge... it's a cable suspension bridge (with cables rusting away for decades now) with hundreds of cars and trucks just waiting to plummet into the ocean! There's a cable tram outside of Albequerque New Mexico that goes 3 miles up Sandia Peak with only one pylon in the middle holding it up. The view is awesome. Stay off that too...
I don't like them one bit, but If I'm going up 16 floors, or coming down, (I have a bad knee on one leg and a cranky hip on the other and they really don't like going down stairs)... I'll risk the elevator. I have run up 16 floors though...but not in a while. I figure if you're destined to drown, you'll never hang. And while I think it's fool hardy to tempt fate, (like standing up on a moving motorcycle seat without a helmet, for instance) I figure what's going to get you is going to get you. I have acrophobia. Had it for as long as I can remember, which is since I was about two. When I was that age, if you wanted to pick me up you best be sitting down because if you were standing I'd scream and punch and scratch face until you put me down. No lie or exageration... Probably why I lower all my cars and send Wife up the ladder to fix the roof or aim the TV antenna. It's weird that those trams don't bother me, except when I have to board the car and it's swaying away from the dock and the dock is up in the air. That freaks me out. Driving on the top deck of a triple or quadruple freeway overp*** curdles my lunch too. Especially if someone else is driving and all I have to entertain me is to look over the side. What I said earlier is true for me. I don't like getting under cars that are on any kind of stand other than the wheels. Ya see, the last earthquake here felt like the house dropped out from under me about a foot. I was sitting down and the chair legs went "thump" on the floor like I was airbourne for an instant. I went outside to check the two cars I have up on stands and they were still on them but they had moved about 1/2" across the frame. If the quake had been more than one "thump" they probably would have fallen. If I had been under there working on one... That's why I'd rather be under something suspended by a KNOWN STRONG cable than something relying on gravity and a stable ground. You never know when that ground is going to become unstable around here. Plus my house is about 2 city blocks from the Long Beach Earthquake fault line. (It runs under Pacific Coast Highway, on the south side of Signal Hill, probably why it's a hill?)
