What's the length and weight of the door?

Can somebody help which size must I buy uplift 600w x4 solar panels

How many Nm ???

it's a really good video, but what name of this Linear Actuator, can you give me the buy link so I can buy it 🥰🥰

I also suggest the emergency disconnect with the pull pin, too. Saves you from having to cut open the door. I would keep your switches, not using the momentary switches, but add a limit switch on the closing function. The LA has its own limit switches and it LOOKS like you installed it such that it is at its full extension when completely lowered. A limit switch when closing will let you press the "Close" side of the circuit without having to stand there while it closes.

Where from did you buy the actuator? Any link?

My suggestion to you is to NOT use that DPDT switch. Use two Momentary SPDT switches and 2 Relays. One SPDT downstairs and one upstairs. Not only can you control from both places but you can control the position. Only drawback is that is not just a one click operation, but you have to press and hold. Like in my video. Except for timers you use SPDT switches. ruclips.net/video/-HLkvI-oJ1A/видео.html Also wrap a pool noodle around it. Makes it quieter. Last if you have a good WiFi connection you could always use a 2CH or 4Ch relay smart switch. It have to be 60 below for it to start affecting it. Besides running the wire in some aluminum flex conduit and boxes, you can always replace the pin in the actuator mounting bracket with a pull pin. The kind that have a little ball bearing at the end. Get a length of steel wire rope and run it to somewhere you can yank on it. Or make a hole next to the mount the size of one of those cable hole covers. The type that are on desks that cover the holes that are meant for cables. And that becomes an access port to pull the pin.

what is the speed

noisy.

Looks good except that if you don't stop via flipping switch to cut power, you'll rip it off the door due to the loft door being fully closed while not at the fully closed limit switch on actuator. I'd either add a arduino controller to be able to stop power at the actual closed loft door position( also being Ble to use it remotely this way)...or figure out some anti binding linkage, slip area up top towards closed. Great job and inspiring me for my project...adding a linear actuator to a giant exhaust wall with the intent of controller the exhaust flow remotely via wifi and remote desktop.

when installing an linear actuator to a window or door like that what are the tricks to install them? by that I mean do you fully extend the actuator if door open and fully retracted if door closed? your hatch opens 90 degs; if I need to open it only 45 degs how do I install it? What advices can you give me, please? Thanks!

I have a 42mm and oh my I cannot get the blade out!! It’s wedged in extremely tight.

The big vertical kanji is "Kakuri Industries, Co." roughly, on the plate is: Shyoushigen Shingashi (resource conservation, White oak heartwood) "Traditionally, this part of the area was rarely used because it was not white. But the quality is not inferior, so this part is now used in order to make the best use of it." Shingashi seems to be the name of this model planer

To remove the blade, they tell you to not strike the plane in the center, you will crack it but on the corners

thats neat how the chip breaker doubles as the wedge. Pretty clever

You could also fit a NE555 Timer Circuit upstairs with Relay, using the same 12v supply, so that it would switch the 240v lighting on/off a few seconds after closing the hatch. Either way, you inspired me to be inventive!

What happens when there is no power ?

How many amps is your 12v power supply?

xD

I foresee many a new actuator replacements in ur future.

Well, you won't be able to sneak any dead bodies into that attic in the middle of the night, that's for sure.

Where did you buy the actuator?

what is the actual actuator you ve used

How many times did you hit the top of the door you need to open/close when you lower/raise the loft hatch...? Why place the switch there and not in the hall way where you have better control of what is open and what is not before lowering the hatch.

You absolutely need to build an enclosure that’s soundproofed with dead-matting and sound proofing glue between two layers of 5/8 drywall for that actuator! That must be 70+ decibels, in a hallway no less! Yikes

Wallace and Grommet 😂

WHISPER QUIET

kiss ass

Cool, but super super loud.

You suck!!!!! You didn’t show the building process....

The mounting location of the actuator is critical, no discussion about that. Seems that the actuator did not reach the full retract position which could actually stress or break off the brackets. A faster actuator might have been a better choice.

Nice! In its simplicity, this is still expandable. A robust Micro-Switch in the Frame could control the light coming on or off. As also mentioned, there are further _Remote_ possibilities with this where you could either change or add a Wireless Module to allow control by Key-Fob. I'm currently replacing the threaded bar in a Scissor Lift, to motorise a platform that I use for Laser Etching. It isn't a necessity but its much nicer pressing one or 2 buttons than cranking a handle! Esp in 2020!!

You could have installed a wireless command and it would have been perfect ! 😉

After you added your ten pounds of noise killing padding around that thing - did you realize that what you really needed was a gas strut - like in your mini-van? Silence is golden - at all hours but especially when children are asleep - and you can't get into the loft!

Friend, No remote required。 we have developed a Linear Actuator controlled by a mobile phone. www.aliexpress.com/item/4000857118404.html?spm=2114.12010612.8148356.53.54fc5b9dZdvRbD

I'm looking for a way to mechanically raise a section of our deck where a dormer use to sit over the exterior steps to the basement. For 10 years I've been lifting that heavy thing, but we're going to sell the house, and I'm sure the next family won't want to deal with the labor of that. This is the closest thing, although opposite and much lighter, that I've found that's even close to what I'm needing. Thanks.

Where can I find the hardware

I can still hear it.

Pretty cool, but a gas piston would do the same thing and be silent.

Attention produit non étanche même au éclaboussure, ne pas sen servir à l extérieur,,,,,!!!

Hi evry good pleas iam from Saudi and am looking for. This pruduct where do you think i can find one Thanks

I love it!

Muito barulhento👂

Why did you reverse the mounting of the actuator?

I have 2 issues with this idea, at least from installing it in my loft. 1 is that the actuator would have to operate in very cold weather and 2, what happens if I need to get into the loft but the actuator is broken! Or a rat or raccoon chewed through an electrical cord up top? There would have to be some kind of emergency release at the bottom.

If you had a small solar panel and a motorbike battery that would save a lot of wiring.

nice idea..what size of this actuator and how big is this port ???

what is the stroke length? Weight (Kg) pull strength? 12V/24V ? Please post such technical information with your post comments.

I do not think you should have been doing this review?you don't seem to know much about planes or how they work.this was pretty much,useless.
