Thank you soooo much for this... it is *exactly* what I wanted. I want to make a dumbwaiter to bring up groceries, send down snack trays for my family while they watch football... I have to tailor it a bit to fit a stairwell/was thinking of way to cover it w a panel then have a dropdown tray that fits a groove in adjoining wall. That should be easy to tailor, just so it does not tip going up and down. P.S. Nerdy High School kid is my 16 yr old son!! THANKS and will send pics:)
Nice design except one important thing, preventing it from passing code. E-stops or Emergency Stop Buttons are NEVER WIRED THROUGH THE PLC!!!! They are always wired directly to the MCR or power source feeding the potential energy source, in this case, the hoist motor. Things fail and sometimes it's in the PLC or the ladder logic (ever program something wrong?) . when that happens, the E stops might accidentally be bypassed. This could be a dangerous device causing injury or death.
I forgot to mention, there is nothing locking the access doors when the cab in not in front of a door. I see there are door interlocks that stop the motion, once a door is open, but when the cat is not in front of a door, and the door is then open, there is a vertical shaft that presents a hazard. its all a bout the safety when designing dumb waiters and elevators!!!!
I think it is not that bad in video: at top there is existing "Over travel Limit switch" from hoist for stopping if top e-stop fails. And emergency button is also not wired to PLC in video. About access door locking I agree - this is missing and not good!
@@weltraumkuh it wouldn't be hard to wire a lock with power to open and connect it to the on floor signal lamp. He probably told his family to only open the door only if the light is on which is fair enough... This is totally safe compared to some of the others i have seen without any interlocks to limit user error.
Very impressive! The welded frames and heavy duty bearing rollers as guides are a seriously nice touch. Do you have the plans posted anywhere else in a static format? I'd love to lay these up against the plans I came up with, and getting usable screen shots out of a a you tube video ain't easy... :)
Nice job, this is what DIY instructional SHOULD look like. Not the shaky camera, poor lighting, even poorer verbal descriptions posted all over UA-cam. You must be an engineer with a few tech writing classes under your belt. On a scale of 1 to 10...9.5. Boring music...1/2 point deduction.
To save money,time, and still get a little exercise, use a manual rope and pulley system. It does not require much strength, and it is easier for the DIY people. It can handle quite a bit of weight and it works when the powers off, that is if you can see it.
for 2 floors, it is a little over engineered, but if it were 3 floors, this would be a great starting point. the logic required for the 3rd floor increases quite a bit.
All good until someone get there hand cut off, or gets killed. And that is highly illegal. For the time and money spend built that death machine you could have bought a real dumbwaiter or a VRC
Nice! Seriously slick project.
Great video, lots of ideas! well done

I like the music - extra credit 5 points plus :)
Windows XP installation music xD nice. Cool vid
That was awesome!!!
Good Job! Gives me lots of ideas.

I'm building this thing now...
Cool.. the company I work for built a lot of automation direct.. I noticed one of your components was made by them

Very well explained.
Also, I've been listening to that music for years now on peoples "on-hold" telephone music. What is it?
mrmattandmrchay Windows XP introduction or setup music.
Great clip burnedcoal. Any chance of getting the schematic drawings link please.,as am currently seeking a DW. musics very soothing by the way. lol

Has anyone found the download he spoke of for the component's?
where to find the link to download the manual
can i find the manual
How loud or quiet is it?
Hello, can I ask you what ZIP link model is being shown in video and cable ? thanks
Its a tidy way of having the PLC I/O's in another location so he can branch them out to where they need to be. Like a multicore on audio setups.
Like popular mechanics!
Whats it for i was never tougjt

This seems way to over engineered,especially if it is only two floors.

A good lawyer would tear your disclaimer apart.
