@@impRZA I can buy chinese ramps, so can I buy chinese surgery online as well? 😄 As fore those ramps, for a Golf-sized car on hard surface, they are more than strong enough if diagonal supports are added to both pillars. I would also connect the ramps together from bottom as well, then they would be even more stable. Now the surface against the floor seems uncomfortably narrow.
@@xl000 Yeah but safer if made by a highly educated Engineer and tested many times for safety and reliability. That is the difference. Even drugs are homemade. Hence the words Clinical TRIALS. As simple humans, we basically try many things until something sticks. Many discoveries were had by failed experiments e.g., Viagra and Post it notes. I love innovation and yes, studied Engineering.
It could be a good idea if it actually was built correctly. This design shown here is perfect if you are trying to kill yourself or destroy your vehicle.
Very good use of dexion shelving! The polystyrene end stops and plasticine took tray only come with the deluxe version. But that nearly doubled the price at £21.99.
And bravo to the designer, we haven't been chased by saber-tooth tigers in the forests for a long time, and somehow we need to regulate the size of our population.
It's an isosceles triangle and the weight is pushing straight down on the two slants and the forces are trying to push the 2 bottom legs apart. There's no lower connecting strut to counter the 2 outward forces. That's how it looks to me. What do you think?
I dont think the bracing is strong enough to prevent it collapsing length ways Whilst it's pivoting those 2 front legs are taking the whole weight of the car...
Step 1: drive car on ramp. Step 2: Change underpants. 3.: Fix car. 4.: Get a friend to back the car off while you direct / pray. 5.: Say bye to friend. 😂
very good, reasonable, stable, strong and relatively lightweeight design. Perfect! The best one I have ever seen. I would recommend to everyone who is looking for the right design.
It is interesting to see this sort of ramp in action, with the way it sorta pivots in the middle. There is a used car lot near me with some, and I had never seen them in use before, always wondering how harsh and how forceful on the front legs they were. I was thinking of making a set myself. The main difference with how I would make them, would be to make them a bit wider, and join them at the ends with some pipe, possibly using a pin system to adjust the width. I would probably just make the platforms wide enough to accomedate a variety of track widths and make the spacing of the ramps fixed.
These need what I borrow from car lot elevated car ramp designs, is a front and rear interconnecting bar to stabilize movement between the two sides and hold the width alignment. Some ramps of this separate design have fallen on their owners. Very important design flaw for all you diyers. Be safe!
Funny idea but if you were to "rotate" the entry triangle upside down, you would avoid doing that whole gymnastics routine when getting up the ramp and still have the exact same height.
but that would be less fun. ramps aren't really much good for anything more than an oil change anyway, and i wouldn't even want to be swinging off a tight sump nut or oil filter under this.
The principle is really cool. They look a bit weak, but i didn't do the math. But a bit of cinderblock under each end for extra safety wouldn't harm, i guess.
No more use than the car been on the floor. What could you possibly change ? The exhaust or underseal the car? . still can't work behind the wheels or running gear ect
The ideas there, but he built it like a 3rd graders bridge project, try again with proper steel, maybe tube or angle; 5/16 thick steel angle or t bar might be more suitable
Could you please specify the height? Its looking like it would still be hard to get under there and i am trying to figure out the perfect height for making one!
This was 5 years ago. Now it is April 2024. How is it holding up any problems with it. Are you still with us? I hope you put some crosspieces in to keep it from collapsing side ways.
Good, but for strenght I see only one piece of metal between the two ramps. That seems not enough for the whole thing to be safe. I would put cross pieces on, not just for transport. It would be good if there were cross pieces when you have a car on it. To keep it from collapsing sideways. But you have been using it for 5 years now and no problem. But it only have to go wrong once and then it's lights out. If you know what I mean.
